Generic, multi-purpose FIFOs. Available as single clock and dual clock version, binary, lfsr, and gray encoded (dual clock only). All are parameterizable and use generic_memories for memory. These FIFOs are fully portable from FPGAs to ASICS.

用matlab 进行QPSK 的BER 仿真并与理论值比较,计算使用Naive Code [00 01 10 11] 时QPSK的BER，并与gray Code 比较,求取8PSK 的gray Code 下的误比特率BER 的解析解-QPSK,BER,Naive Code,gray Code, 8PSK
