Prevent reading data from an empty FIFO from blocking

WebJun 4, 2014 · With your current code (and my board) when you depress a switch I was getting many contiguous reads or writes. So a single press of the wr switch would fill the fifo and a single press of the read switch would empty the fifo. I renamed your rd input signal to rd_in and the wr signal to wr_in and added the following code: always @ ( posedge clk ...

WebThe FIFO is empty when the read pointer catches up with the write pointer, and full when the write pointer catches up with read pointer. One way of accomplishing this is by making each counter one bit wider than required. All counter bits except the MSB are used to address the FIFO array. In this configuration, every location in the FIFO is ... WebSep 15, 2024 · When empty is asserted, VALID is deasserted. In the standard read mode, when empty is asserted, VALID is asserted for 1 clock cycle. The FWFT feature also increases the effective read depth of the FIFO by two read words. The FWFT feature adds two clock cycle latency to the deassertion of empty, when the first data is written into a …

One method for full/empty detection is to use M+1 bit registers for the read and write pointer. If all M+1 bits match, then the FIFO is empty. However, if all bits match except the MSB, then the FIFO is full.

WebFeb 1, 2024 · This is the simplest page replacement algorithm. In this algorithm, operating system keeps track of all pages in the memory in a queue, oldest page is in the front of the queue.
