Get fpga chip model information: like ROM read/write module, filter module, key display control module, are logic can be realized, so you can directly write FPGA program to achieve the corresponding interface. This common Altera Xilinx can be.
If the model starts with EPM ********, that is, the MAX series (of which MAX represents the array matrix), is the CPLD, ALTERA's FPGA product family code for EP or EPF.
Typical product model meanings are as follows: EPF10K10: FLEX10K series of FPGAs. Typical logic scale is 10K effective logic gates. EPF10K30E: FLEX10KE series FPGA, the logic size is 3 times of EPF10K10.
Basic structure:
FPGA devices belong to a kind of semi-custom circuits in special-purpose integrated circuits, which are programmable logic arrays, and can effectively solve the problem of the original devices with fewer gates.The basic structure of FPGAs includes programmable input/output units, configurable logic blocks, digital clock management modules, embedded block RAM, cabling resources, embedded special-purpose hardware, and underlying embedded functionality. hard core, the bottom of the embedded functional units.
Because FPGAs are rich in wiring resources, reproducible programming and high integration, low investment characteristics, in the field of digital circuit design has been widely used.FPGA design flow includes algorithm design, code simulation, and design, board debugging, the designer as well as the actual needs of the algorithmic architecture.
