VHDL example of DCFIFO

Hi Scott,

For example, the dcfifo empty flag. It is active low yet the name is "rdempty". We would have called it "nRdEmpty" or something similar to show it was negative logic.

No, its not active low. The FIFO is empty when its got nothing in it, and hence the rdempty signal is high. When you write to the FIFO it goes low, as the FIFO is no longer empty.

What likely confused you is that the rdempty signal starts out high (active) after a reset, and then goes low (inactive) once written.

Cheers,

Dave
