WebCan somebody show me the rptr, wptr, and testbench for an asynchronous FIFO? Here is my source code: module dual_port_ram (data, waddr, we, raddr, clk, q); parameter WIDTH = 4; parameter ADDR_BITS = 4; parameter DEPTH = 2**ADDR_BITS; input [WIDTH-1:0] data; input [ADDR_BITS-1:0] waddr; input [ADDR_BITS-1:0] raddr; input we, clk; output WebCorrectly designed FIFOs can increase bandwidth across the interface while still maintaining reliable communication across channels. Dual Clock Asynchronous FIFO can be viewed as container of data where sender pushes the data in at source clock rate and receiver pops out the data at destination clock rate. fleece meadow campsite kington https://fierytech.net
