| DINT2FP Integer to Floating Point Pipelined Converter ver 2.32 OVERVIEW The DINT2FP is the pipelined integer to floating point converter. The input and output numbers format is according to IEEE-754 standard. DINT2FP supports double word integers (4 Bytes) and single precision real numbers. Convert operation is pipelined to 3 levels. Input data are fed every clock cycle. The first result appears after latency equal to 3 clock periods and next results are available each clock cycle. Full precision and accuracy are accomplished. Fully synthesizable, static synchronous design with no internal tri-states DELIVERABLES Source code: VHDL Source Code or/and VERILOG Source Code or/and Encrypted, or plain text EDIF netlist VHDL & VERILOG test bench environment Active-HDL automatic simulation macros ModelSim automatic simulation macros NCSim automatic simulation macros Tests with reference responses Technical documentation Installation notes HDL core specification Datasheet Synthesis scripts Example application Technical support IP Core implementation support 3 months maintenance APPLICATION Math coprocessors DSP algorithms Embedded arithmetic coprocessor Data processing & control KEY FEATURES Full IEEE-754 compliance Double word integer input numbers (4 Bytes) Single precision real output numbers Simple interface No programming required 3 levels pipelining Full accuracy and precision Results available at every clock Fully configurable Delivery the IP Core updates, minor and major versions changes Delivery the documentation updates Phone & email support LICENSING Comprehensible and clearly defined licensing methods without royalty fees make using of IP Core easy and simply. Single Design license allows using IP Core in single FPGA bitstream and ASIC implemenhttp://www.DigitalCoreDesign.com http://www.dcd.pl All trademarks mentioned in this document are trademarks of their respective owners.

Unlimited Designs license allows using IP Core in unlimited number of FPGA bitstreams and ASIC implementations. In all cases number of IP Core instantiations within a design, and number of manufactured chips are unlimited. There is no time of use limitations. Single Design license for VHDL, Verilog source code called HDL BLOCK DIAGRAM datai(31:0) Argument Checker Main FP Pipelined Unit Result Composer datao(31:0) en rst clk Source Encrypted, or plain text EDIF called Netlist Unlimited Designs license for HDL Source Netlist Arguments Checker - performs input data analyze against IEEE-754 number standard compliance. The appropriate numbers and information about the input data classes are given as the results to Main FP Pipelined Unit. Main FP Pipelined Unit - performs integer to floating point conversion. Gives the complex information about the results to Result Composer module. Result Composer - performs result rounding function, and data alignment to IEEE-754 standard.
