你可以参加 asic@egroups.com的讨论组， 或者与 zeyaohan@263.net联系，目前它们提供IP cores,包括： （VHDL或Verilog代码级，大部分可综合，可生成ASIC或用FPGA等来实现。） Comm Controllers ATM AALx Eth MAC 10/100Mbps FireWire I2C IP Engine Serial UART USB Controller Coprocessors Floating Point DSP Cores FIR Filter MAC unit Memory Cores FIFO buffer Dual port RAM Signal port RAM LUT model DRAM model Arithmetic Cores Disributed Arithmetic MAC ECC Cores Reed-Solomon Encoder/Decoder Viterbi Decoder Microprocessors Mini-Risc OpenRISC 1000 OpenRISC 2000 System Controllers ATA-3 (EIDE) PCI 64 Bridge SDRAM Controller Video Controllers CRT6845 CRT (VGA) LCD Prototype Boards Micro FPGA board OCRP-1 board OCRP-2 board CPLD board 另外还有HW Design Case、Free IP Cores、Free Eda tools等， 从我收到的列表是这样： 1.
