Implementation and Verification of Asynchronous FIFO Under

WebSynchronous FIFO. First In First Out (FIFO) is a very popular and useful design block for purpose of synchronization and a handshaking mechanism between the modules. Depth of FIFO: The number of slots or rows in FIFO is called the depth of the FIFO. Width of FIFO: The number of bits that can be stored in each slot or row is called the width of ... WebMar 23, 2024 · When de-asserted, does not write data to FIFO. When it is asserted, data can be written to FIFO if wr_n is asserted. rd_n: It is an active low signal. When asserted, data is driven onto ‘data’ bus from FIFO. wr_n: It is an active low signal.

WebThe remaining no. of bytes to be stored in the FIFO = 120 – 37 = 83. So, the FIFO which has to be in this scenario must be capable of storing 83 data items. So, the minimum depth of the FIFO should be 83. Case – 4 : f A > f B with duty cycles given for wr_enb and rd_enb. Writing frequency = f A = 80MHz. Reading Frequency = f B = 50MHz.
