This paper introduces three codes: binary code, gray code and shift code. In this paper, we use Verilog HDL language and use these three different codes to design the FIFO empty and full state judgment module,
The simulation testcases available useIcarus VerilogandSVUTtool to run the tests. The FIFO is fully functional and used in many successful projects. Usage RTL sources are present in RTL folder under three flavors: rtl/async_fifo.v: a basic asynchronous dual-clock FIFO ...
异步FIFO_Asynchronous FIFO
It applies true synchronous reset to block RAM though the FIFO receives the asynchronous reset. There will not be a situation where some part of logic is out of reset and some part is still in reset as long as its wr_rst_busy signal is used by the design to hold the data flow. The...
San Jose, CA Voted Best Paper 1st Place ABSTRACT An interesting technique for doing FIFO design is to perform asynchronous comparisons between the FIFO write and read pointers that are generated in clock domains that are asynchronous to each other. The asynchronous FIFO pointer comparison technique ...
In the Verilog code of Example 1a and the VHDL code of Example 1b, a flip-flop is used to capture data and then its output is passed through a follower flip-flop. The first stage of this design is reset with a synchronous reset. The second stage is a follower flip-flop and is not...
