1.3 description OMAP-L137 low-power applications processor sprs563a ? september 2008 ? revised october 2008 www.ti.com the OMAP-L137 is a low-power applications processor based on an arm926ej-s? and a c674x? dsp core. it provides significantly lower power than other members of the tms320c6000? platform of dsps. the OMAP-L137 enables oems and odms to quickly bring to market devices featuring robust operating systems support, rich user interfaces, and high processing performance life through the maximum flexibility of a fully integrated mixed processor solution. the dual-core architecture of the OMAP-L137 provides benefits of both dsp and reduced instruction set computer (risc) technologies, incorporating a high-performance tms320c674x dsp core and an arm926ej-s core. the arm926ej-s is a 32-bit risc processor core that performs 32-bit or 16-bit instructions and processes 32-bit, 16-bit, or 8-bit data. the core uses pipelining so that all parts of the processor and memory system can operate continuously. the arm core has a coprocessor 15 (cp15), protection module, and data and program memory management units (mmus) with table look-aside buffers. it has separate 16k-byte instruction and 16k-byte data caches. both are four-way associative with virtual index virtual tag (vivt). the arm core also has a 8kb ram (vector table) and 64kb rom. the OMAP-L137 dsp core uses a two-level cache-based architecture. the level 1 program cache (l1p) is a 32kb direct mapped cache and the level 1 data cache (l1d) is a 32kb 2-way set-associative cache. the level 2 program cache (l2p) consists of a 256kb memory space that is shared between program and data space. l2 also has a 1024kb rom. l2 memory can be configured as mapped memory, cache, or combinations of the two. although the dsp l2 is accessible by arm and other hosts in the system, an additional 128kb ram shared memory is available for use by other hosts without affecting dsp performance. the peripheral set includes: a 10/100 mb/s ethernet mac (emac) with a management data input/output (mdio) module; two inter-integrated circuit (i2c) bus interfaces; 3 multichannel audio serial port (mcasp) with 16/12/4 serializers and fifo buffers; 2 64-bit general-purpose timers each configurable (one configurable as watchdog); a configurable 16-bit host port interface (hpi); up to 8 banks of 16 pins of general-purpose input/output (gpio) with programmable interrupt/event generation modes, multiplexed with other peripherals; 3 uart interfaces (one with rts and cts); 3 enhanced high-resolution pulse width modulator (ehrpwm) peripherals; 3 32-bit enhanced capture (ecap) module peripherals which can be configured as 3 capture inputs or 3 auxiliary pulse width modulator (apwm) outputs; 2 32-bit enhanced quadrature pulse (eqep) peripherals; and 2 external memory interfaces: an asynchronous and sdram external memory interface (emifa) for slower memories or peripherals, and a higher speed memory interface (emifb) for sdram. the ethernet media access controller (emac) provides an efficient interface between the OMAP-L137 and the network. the emac supports both 10base-t and 100base-tx, or 10 mbits/second (mbps) and 100 mbps in either half- or full-duplex mode. additionally an management data input/output (mdio) interface is available for phy configuration. the hpi, i2c, spi, usb1.1 and usb2.0 ports allow the OMAP-L137 to easily control peripheral devices and/or communicate with host processors. the rich peripheral set provides the ability to control external peripheral devices and communicate with external processors. for details on each of the peripherals, see the related sections later in this document and the associated peripheral reference guides. the OMAP-L137 has a complete set of development tools for both the arm and dsp. these include c compilers, a dsp assembly optimizer to simplify programming and scheduling, and a windows? debugger interface for visibility into source code execution.

3.4.1 c674x dsp cpu description OMAP-L137 low-power applications processor www.ti.com sprs563a ? september 2008 ? revised october 2008 the c674x central processing unit (cpu) consists of eight functional units, two register files, and two data paths as shown in figure 3-2 . the two general-purpose register files (a and b) each contain 32 32-bit registers for a total of 64 registers. the general-purpose registers can be used for data or can be data address pointers. the data types supported include packed 8-bit data, packed 16-bit data, 32-bit data, 40-bit data, and 64-bit data. values larger than 32 bits, such as 40-bit-long or 64-bit-long values are stored in register pairs, with the 32 lsbs of data placed in an even register and the remaining 8 or 32 msbs in the next upper register (which is always an odd-numbered register). the eight functional units (.m1, .l1, .d1, .s1, .m2, .l2, .d2, and .s2) are each capable of executing one instruction every clock cycle. the .m functional units perform all multiply operations. the .s and .l units perform a general set of arithmetic, logical, and branch functions. the .d units primarily load data from memory to the register file and store results from the register file into memory. the c674x cpu combines the performance of the c64x+ core with the floating-point capabilities of the c67x core. each c674x .m unit can perform one of the following each clock cycle: one 32 x 32 bit multiply, one 16 x 32 bit multiply, two 16 x 16 bit multiplies, two 16 x 32 bit multiplies, two 16 x 16 bit multiplies with add/subtract capabilities, four 8 x 8 bit multiplies, four 8 x 8 bit multiplies with add operations, and four 16 x 16 multiplies with add/subtract capabilities (including a complex multiply). there is also support for galois field multiplication for 8-bit and 32-bit data. many communications algorithms such as ffts and modems require complex multiplication. the complex multiply (cmpy) instruction takes for 16-bit inputs and produces a 32-bit real and a 32-bit imaginary output. there are also complex multiplies with rounding capability that produces one 32-bit packed output that contain 16-bit real and 16-bit imaginary values. the 32 x 32 bit multiply instructions provide the extended precision necessary for high-precision algorithms on a variety of signed and unsigned 32-bit data types. the .l or (arithmetic logic unit) now incorporates the ability to do parallel add/subtract operations on a pair of common inputs. versions of this instruction exist to work on 32-bit data or on pairs of 16-bit data performing dual 16-bit add and subtracts in parallel. there are also saturated forms of these instructions. the c674x core enhances the .s unit in several ways. on the previous cores, dual 16-bit min2 and max2 comparisons were only available on the .l units. on the c674x core they are also available on the .s unit which increases the performance of algorithms that do searching and sorting. finally, to increase data packing and unpacking throughput, the .s unit allows sustained high performance for the quad 8-bit/16-bit and dual 16-bit instructions. unpack instructions prepare 8-bit data for parallel 16-bit operations. pack instructions return parallel results to output precision including saturation support. other new features include: sploop - a small instruction buffer in the cpu that aids in creation of software pipelining loops where multiple iterations of a loop are executed in parallel. the sploop buffer reduces the code size associated with software pipelining. furthermore, loops in the sploop buffer are fully interruptible. compact instructions - the native instruction size for the c6000 devices is 32 bits. many common instructions such as mpy, and, or, add, and sub can be expressed as 16 bits if the c674x compiler can restrict the code to use certain registers in the register file. this compression is performed by the code generation tools. instruction set enhancement - as noted above, there are new instructions such as 32-bit multiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit galois field multiplication. exceptions handling - intended to aid the programmer in isolating bugs. the c674x cpu is able to detect and respond to exceptions, both from internally detected sources (such as illegal op-codes) and from system events (such as a watchdog time expiration). privilege - defines user and supervisor modes of operation, allowing the operating system to give a basic level of protection to sensitive resources. local memory is divided into multiple pages, each with read, write, and execute permissions. submit documentation feedback device overview 13 product preview

6.6.2 device clock generation OMAP-L137 low-power applications processor sprs563a ? september 2008 ? revised october 2008 www.ti.com pll0 is controlled by pll controller 0. the pllc0 manages the clock ratios, alignment, and gating for the system clocks to the chip. the pllc is responsible for controlling all modes of the pll through software, in terms of pre-division of the clock inputs, multiply factor within the pll, and post-division for each of the chip-level clocks from the pll output. the pllc also controls reset propagation through the chip, clock alignment, and test points. pllc0 generates several clocks from the pll0 output clock for use by the various processors and modules. these are summarized in table 6-3 . the clock ratios between sysclk1, sysclk2, sysclk4 and sysclk6 must always be maintained as shown in the table. table 6-3. system pllc0 output clocks output used by default ratio (relative to notes clock sysclk1) sysclk1 dsp /1 no required ratio sysclk2 arm ram, arm rom, edma, dsp ports, emifb (ports to switch /2 sysclk1 / 2 fabric), ecap 0/1/2, epwm 0/1/2, eqep 0/1, shared ram, lcdc, mcasp/fifo 0/1/2, spi 1, uhpi, usb2.0 (logic), uart 1/2, hrpwm 0/1/2 sysclk3 emifa /3 no required ratio sysclk4 syscfg, interrupt controller, pllc0, psc 0, emac/mdio, gpio, /4 sysclk1 / 4 i2c 1, psc 1, usb1.1 sysclk5 emifb /3 no required ratio sysclk6 arm subsystem /1 sysclk1 / 1 sysclk7 rmii clock to emac /6 no required ratio ; should be set to 50 mhz auxclk mcasp auxclk,rtc,timer64p0,timer64p1 n/a no required ratio usb48 usb2.0 phy, usb1.1 logic n/a no required ratio; should be set to 48 mhz usb12 usb2.0 phy, usb1.1 logic n/a no required ratio; 12 mhz, generated by the usb1 module by dividing usb48 by 4. div4p5 133mhz clock source for emifb pll output/4.5 no required ratio the divide values in the pll controller 0 for sysclk1/sysclk6, sysclk2 and sysclk4 are not fixed so that user can change the divide values for power saving reasons. but users are responsible to guarantee that the divide ratios between these clock domains must be fixed to 1:2:4. although the pll is capable of running at 600 mhz, the sysclk dividers in the pllc0 are not (maximum 410 mhz). for this reason, the post-divider in the pllc0 should be configured for /2 to provide 300 mhz to each of the sysclk dividers. the div4p5 (/4.5) hardware clock divider is provided to generate 133 mhz from the 600 mhz pll clock for use as clocks to the emifs. 84 peripheral information and electrical specifications submit documentation feedback product preview

6.8 general-purpose input/output (gpio) 6.8.1 gpio register description(s) OMAP-L137 low-power applications processor sprs563a ? september 2008 ? revised october 2008 www.ti.com the gpio peripheral provides general-purpose pins that can be configured as either inputs or outputs. when configured as an output, a write to an internal register can control the state driven on the output pin. when configured as an input, the state of the input is detectable by reading the state of an internal register. in addition, the gpio peripheral can produce cpu interrupts and edma events in different interrupt/event generation modes. the gpio peripheral provides generic connections to external devices. the gpio pins are grouped into banks of 16 pins per bank (i.e., bank 0 consists of gpio [0:15]). the OMAP-L137 gpio peripheral supports the following: up to 128 pins on zkb package configurable as gpio external interrupt and dma request capability ? every gpio pin may be configured to generate an interrupt request on detection of rising and/or falling edges on the pin. ? the interrupt requests within each bank are combined (logical or) to create eight unique bank level interrupt requests. ? the bank level interrupt service routine may poll the intstatx register for its bank to determine which pin(s) have triggered the interrupt. ? gpio banks 0, 1, 2, 3, 4, 5, 6, and 7 interrupts assigned to arm intc interrupt requests 42, 43, 44, 45, 46, 47, 48, and 49 respectively ? gpio banks 0, 1, 2, 3, 4, 5, 6, and 7 interrupts assigned to dsp events 65, 41, 49, 52, 54, 59, 62 and 72 respectively ? additionally, gpio banks 0, 1, 2, 3, 4, and 5 interrupts assigned to edma events 6, 7, 22, 23, 28, and 29 respectively. set/clear functionality: firmware writes 1 to corresponding bit position(s) to set or to clear gpio signal(s). this allows multiple firmware processes to toggle gpio output signals without critical section protection (disable interrupts, program gpio, re-enable interrupts, to prevent context switching to anther process during gpio programming). separate input/output registers output register in addition to set/clear so that, if preferred by firmware, some gpio output signals can be toggled by direct write to the output register(s). output register, when read, reflects output drive status. this, in addition to the input register reflecting pin status and open-drain i/o cell, allows wired logic be implemented. the memory map for the gpio registers is shown in table 6-8 . see the OMAP-L137 applications processor dsp peripherals overview reference guide. ? literature number spruga6 for more details. table 6-8. gpio registers gpio acronym register description byte address 0x01e2 6000 rev peripheral revision register 0x01e2 6004 reserved reserved 0x01e2 6008 binten gpio interrupt per-bank enable register gpio banks 0 and 1 0x01e2 6010 dir01 gpio banks 0 and 1 direction register 0x01e2 6014 out_data01 gpio banks 0 and 1 output data register 0x01e2 6018 set_data01 gpio banks 0 and 1 set data register 0x01e2 601c clr_data01 gpio banks 0 and 1 clear data register 0x01e2 6020 in_data01 gpio banks 0 and 1 input data register 0x01e2 6024 set_ris_trig01 gpio banks 0 and 1 set rising edge interrupt register peripheral information and electrical specifications 96 submit documentation feedback product preview

6.10 external memory interface a (emifa) 6.10.1 emifa asynchronous memory support 6.10.2 emifa synchronous dram memory support 6.10.3 emifa connection examples OMAP-L137 low-power applications processor sprs563a ? september 2008 ? revised october 2008 www.ti.com emifa is one of two external memory interfaces supported on the OMAP-L137 . it is primarily intended to support asynchronous memory types, such as nand and nor flash and asynchronous sram. however on OMAP-L137 emifa also provides a secondary interface to sdram. emifa supports asynchronous: sram memories nand flash memories nor flash memories the emifa data bus width is up to 16-bits on the zkb package . the device supports up to fifteen address lines and an external wait/interrupt input. up to four asynchronous chip selects are supported by emifa (ema_cs[5:2]) . all four chip selects are available on the zkb package. each chip select has the following individually programmable attributes: data bus width read cycle timings: setup, hold, strobe write cycle timings: setup, hold, strobe bus turn around time extended wait option with programmable timeout select strobe option nand flash controller supports 1-bit and 4-bit ecc calculation on blocks of 512 bytes. the OMAP-L137 zkb package supports 16-bit sdram in addition to the asynchronous memories listed in section 6.10.1 . it has a single sdram chip select (ema_cs[0]). sdram configurations that are supported are: one, two, and four bank sdram devices devices with eight, nine, ten, and eleven column address cas latency of two or three clock cycles sixteen bit data bus width 3.3v lvcmos interface additionally, the sdram interface of emifa supports placing the sdram in self refresh and powerdown modes. self refresh mode allows the sdram to be put into a low power state while still retaining memory contents; since the sdram will continue to refresh itself even without clocks from the dsp. powerdown mode achieves even lower power, except the dsp must periodically wake the sdram up and issue refreshes if data retention is required. finally, note that the emifa does not support mobile sdram devices. figure 6-11 illustrates an example of how sdram, nor, and nand flash devices might be connected to emifa of a OMAP-L137 device simultaneously. the sdram chip select must be ema_cs[0]. note that the nor flash is connected to ema_cs[2] and the nand flash is connected to ema_cs[3] in this example. note that any type of asynchronous memory may be connected to ema_cs[5:2]. the on-chip bootloader makes some assumptions on which chip select the contains the boot image, and this depends on the boot mode. for nor boot mode; the on-chip bootloader requires that the image be stored in nor flash on ema_cs[2]. for nand boot mode, the bootloader requires that the boot image is stored in nand flash on ema_cs[3]. it is always possible to have the image span multiple chip selects, but this must be supported by second stage boot code stored in the external flash. peripheral information and electrical specifications 104 submit documentation feedback product preview
OMAP-L137 low-power applications processor www.ti.com sprs563a ? september 2008 ? revised october 2008 a likely use case with more than one emifa chip select used for nand flash is illustrated in figure 6-12 . this figure shows how two multiplane nand flash devices with two chip selects each would connect to the emifa. in this case if nand is the boot memory, then the boot image needs to be stored in the nand area selected by ema_cs[3]. part of the application image could spill over into the nand regions selected by other emifa chip selects; but would rely on the code stored in the ema_cs[3] area to bootload it. figure 6-11.

6.16 serial peripheral interface ports (spi0, spi1) OMAP-L137 low-power applications processor sprs563a ? september 2008 ? revised october 2008 www.ti.com figure 6-35 is a block diagram of the spi module, which is a simple shift register and buffer plus control logic. data is written to the shift register before transmission occurs and is read from the buffer at the end of transmission. the spi can operate either as a master, in which case, it initiates a transfer and drives the spix_clk pin, or as a slave. four clock phase and polarity options are supported as well as many data formatting options. figure 6-35. block diagram of spi module the spi supports 3-, 4-, and 5-pin operation with three basic pins (spix_clk, spix_simo, and spix_somi) and two optional pins ( spix_scs, spix_ena). the optional spix_scs (slave chip select) pin is most useful to enable in slave mode when there are other slave devices on the same spi port. the OMAP-L137 will only shift data and drive the spix_somi pin when spix_scs is held low. in slave mode, spix_ena is an optional output and can be driven in either a push-pull or open-drain manner. the spix_ena output provides the status of the internal transmit buffer (spidat0/1 registers). in four-pin mode with the enable option, spix_ena is asserted only when the transmit buffer is full, indicating that the slave is ready to begin another transfer. in five-pin mode, the spix_ena is additionally qualified by spix_scs being asserted. this allows a single handshake line to be shared by multiple slaves on the same spi bus. in master mode, the spix_ena pin is an optional input and the master can be configured to delay the start of the next transfer until the slave asserts spix_ena. the addition of this handshake signal simplifies spi communications and, on average, increases spi bus throughput since the master does not need to delay each transfer long enough to allow for the worst-case latency of the slave device. instead, each transfer can begin as soon as both the master and slave have actually serviced the previous spi transfer. 146 peripheral information and electrical specifications submit documentation feedback product preview peripheral configuration bus interrupt and dma requests 16-bit shift register 16-bit buffer gpio control (all pins) state machine clock control spix_simospix_somi spix_ena spix_scs spix_clk
