Honored ContributorFIFO IP is getting empty at a faster rate
Hi, I'm using a FIFO IP with width of the fifo being 16 bit and the depth of the fifo buffer is 16384 words. I'm using the MAX10 development kit and interfacing it with Matlab. The baud rate is...

Honored Contributor --- Quote Start --- You never indicate the rate that data is being written to the FIFO. --- Quote End --- Hi, The clock connected to the fifo IP core is 50 MHz, and my data is 16 bit and the depth of the buffer is 16384. So if I do the calculation then a data is being written into the buffer in 2x10^-8 sec, so the total time to fill up the buffer is ( (1/50MHz) * 16 * 16384 = 0.005 sec ). The baud rate is set at 115200 bps so the fifo is getting completely filled up at a faster rate than it's being read out. In this case I will always have some data left in the fifo. I think I messed up the calculation( by not taking into consideration the write request ). Please kindly correct me if I'm wrong. Thanks,
