3 scd7365 rev a preliminary 11/16/05 aeroflex plainview description the mip7365 microprocessor is a highly integrated symmetric superscalar mi croprocessor capable of issuing two instructions each processor cycle. it has two highperforman ce 64-bit integer units as well as a high-throughput, fully pipelined 64-bit fl oating point unit. the mip7365 integrates 16 kbytes 4-way set associative instruction and data caches along with an integrated 256 kbytes 4-way set associative secondary cache. the primary data and secondary caches are write-back and non-blocking. the memory management unit contains a 64/48-entry fully associative tlb and a 64-bit system interface supporting multiple outstanding reads with out- of-order return and hardware pr ioritized and vectored interrupts. the mip7365 is available in a 216-exposedpad? package. th e 216-exposedpad package is pin compatible with previous rm7965 and the rm5261a exposedpad products. the mip7365 ideally suits high-end embedded control applic ations such as internetworking, high-performance image manipulation, high-speed printing, and 3- d visualization. the mip7365 is also applicable to the low end workstation market where its balanced integer and floating-point performance provid es outstanding price/performance. for additional detail information regarding the operation of th e pmc-sierra see the latest pmc- sierra datasheet for the rm7065c family microprocessors data sheet, issue no. 3: january, 2004
4 scd7365 rev a preliminary 11/16/05 aeroflex plainview pin descriptions the following is a list of contro l, data, clock, interrupt, and miscellaneous pins of mip7365. system interface pin name type description extrqst* input external request signals that the extern al agent is submitting an external request. release* output release interface signals that the processor is releasi ng the system interface to slave state rdrdy* input read ready signals that an external agen t can now accept a processor read. wrrdy* input write ready signals that an external agent can now accept a processor write request. validin* input valid input signals that an external agent is now driving a valid address or data on the bus and a valid command or data identifier on the syscmd bus. validout* output valid output signals that the processor is now driving a valid address or data on the sysad bus and a valid command or data identifier on the syscmd bus. prqst* output processor request when asserted this signal requests that contro l of the system interface be returned to the processor. this is enabled by mode bit 26 pack* input processor acknowledge when asserted, in response to prqst*, this si gnal indicates to the processor that it has been granted control of the system interface. rspswap* input response swap rspswap* is used by the external agent to signa l the processor when it is about to return a memory reference out of order; i.e., of two outstanding memory references, the data for the second reference is being returned ahead of the data for the first reference. in order that the processor will have time to switch the address to the tertiary cache, this signal must be asserted a minimum of two cycles prior to the data itself being presented. note that this signal works as a toggle; i.e., for each cycle that it is held asserted th e order of return is reversed. by default, anytime the processor issues a s econd read it is assumed that the reads will be returned in order; i.e., no action is required if the reads are indeed returned in order. this is enabled by mode bit 26. rdtype output read type during the address cycle of a read request, rdty pe indicates whether the read request is an instruction read or a data read. sysad[63:0] input/output system address/data bus a 64-bit address and data bus for communication be tween the processor and an external agent. sysadc[7:0] input/output system address/data check bus an 8-bit bus containing parity check bi ts for the sysad bus during data cycles. syscmd[8:0] input/output system command/data identifier bus a 9-bit bus for command and data identifier transmission between the processor and an external agent. syscmdp input/output system command/data identifier bus parity for the mip7365, unused on input and zero on output.
5 scd7365 rev a preliminary 11/16/05 aeroflex plainview clock/control interface pin name type description master clock input system clock master clock input used as the system interface reference clock. all output timings are relative to this input clock. pipeline operation frequency is derived by multiplying this clock up by the factor selected during boot initialization. power supply pin name type description vccint input power supply for core. vccio input power supply for i/o. vccp input vcc for pll quiet vccint for the internal ph ase locked loop. must be connect ed to vccint th rough a filter circuit. vccj input power supply used for jtag. vss input ground return. vssp input vss for pll quiet vss for the internal phase locked loop. must be connected to vss through a filter circuit. interrupt interface pin name type description int[9:0]* input interrupt ten general processor interrupts, bit-wise ored with bits 9:0 of the interrupt register. nmi* input non-maskable interrupt non-maskable interrupt, ored with bit 15 of the interrupt register (bit 6 in r5000 compatibility mode). jtag interface pin name type description jtdi input jtag data in jtck input jtag clock input jtdo output jtag data out jtms input jtag command jtrst* input jtag reset. notes: 1. the jtrst* input was added to the rm70xxc and rm79xx cp us to directly control the reset to the jtag state machine. jtag boundary scan test equipment must be able to drive jtrst* high to allow jtag boundary scan operation. 2. the jtrst* input must be connected to gnd ( vss ) through a 220 to 1 k pull-down resistor to force the jtag state machine into the reset state to allow normal operati on (jtag boundary scan mode disabled). 3. the jtag interface electrical characteristics are dependent on the vccj level chosen (2.5 v or 3.3 v).
6 scd7365 rev a preliminary 11/16/05 aeroflex plainview initialization interface pin name type description bigendian input big endian / little endian control allows the system to change the processor addressing vccok input vcc is ok when asserted, this signal indicate s to the mip7365 that the vccint power supply has been above the recommended value for more than 100 milliseconds and will remain stable. the assertion of vccok initiates the reading of the boot-time mode control serial stream. coldreset* input cold reset this signal must be asserted for a power on reset or a cold reset. coldreset must be de-asserted synchronously with sysclock. reset* input reset this signal must be asserted for any reset se quence. it may be asserted synchronously or asynchronously for a cold reset, or synchr onously to initiate a warm reset. reset must be de-asserted synchronously with sysclock. modeclock output boot mode clock serial boot-mode data clock output at the system clock frequency divided by two hundred and fifty six. modein input boot mode data in serial boot-mode data input.
