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.


- Written in Verilog
- Fully Synthesizable (FPGA & ASIC libraries)
- Parameterized
- Single and Dual Clock


- All FIFOs that are release are done. They have been simulated and most of them have been used in one way or another in one of my projects. Some have been verified in real hardware.
- October 2003, Added a dual clock FIFO that is gray code encoded (fully parameterizable)
