WebApr 11, 2008 · Synchronous FIFO's operate within the same clock frequency, ie, both read and write use a single/same clock frequency. These FIFOs can be used like data buffers. … WebFIFO ports: we add data_in, data_out, wen , ren, F and E. Also we keep wptr and rptr internal which is a better option. Also it is sequential so we need a clock and reset. Combinational is difficult for a fifo. It is not easy to control. 9. Multiple read ports: It is a little confusing. One write pointer and many read pointers. 10.
