Dual-Clock Asynchronous FIFO in SystemVerilog

WebAbout Asynchronous FIFO Devices. Asynchronous FIFOs are a type of data buffer, where the first byte to arrive at the input is the first to leave at the output. In a computer system, the operating system’s algorithm schedules CPU time for each process according to the order in which it is received. An asynchronous FIFO will queue the data and ... WebApr 18, 2014 · In this FIFO, I use gray code counters for the read and write pointers to the core memory. These multi-bit pointers must be synchronized to the opposite clock domains to compute full and empty flags (e.g. rdptr is synchronized to wclk to compare against the wptr to determine the full flag.) I am using 2-stage flops in the synchronizer to reduce ... WebFeb 1, 2013 · 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. ts4 infant eyes

"WebSep 16, 2024 · To check if Asynchronous FIFO is working as expected, write some data through FIFO, read it back and compare it. If the data written matches the data that is read then it means that the design is working fine. To check this, copy the following python code in text editor and save it as ‘async_test.py’. the ‘ftd2xx’ Python library. " - Designware async fifo

WebAug 5, 2024 · I think asynchronous FIFO actually internally uses gray code counter to pass the write/read address pointer across the two clock domains.
