FPGA Asynchronous FIFO设计思路(2) 首先讨论格雷码的编码方式: 先看4bit的格雷码,当MSB为0时,正向计数,当MSB为1时,即指针已经走过一遍了,最高位翻转,此时的格雷码是反向计数,这其中整套数据以最大值(深度)为对称中心,每一个数均符合格雷码的要求,即下一个状态比上一个状态只有1bit的变化。 3bit的格雷码,在最...
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, thus solving the challenge of glitch. The semi-stable state challenge is solved ...

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 ...
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 ...
Asynchronous FIFO Design Based on Verilog With the rapid development of integrated circuits, asynchronous First Input First Output (FIFO) is often used to solve the problem of data transmission acr... Y Xu - 《Highlights in Science Engineering & Technology》 被引量: 0发表: 2023年 Review on th...
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...
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...
