[主持人:ChinaECNet] 各位觀眾,現在用戶提問很踴躍,專家正在逐一回答。請耐心等待您問題的答案,同一問題請不要多次提交。  [2004-4-6 11:03:46]
[问:mi040606] What is the main advantage of the CPLD and FPGA?Which one is better in cost and performance? 
[答:Susan] It depends on what is your design.  For FPGA, it has rich register resource and has more LE, normally it targets larger, complex and requires a lots of registers designs.  If your design needs more logic, like decoder, than CPLD will be better.  CPLD has advantage at instant on, single chip, and non-Volatility.  FPFA has advantages at high desnities, embedded SRAM, PLLS and IP.  [2004-4-6 11:05:28]
