-// This FIFO exists to provide an intermediate point for the data on its
-// long trek from one RAM (in the buffer pool) to another (in the longfifo)
-// The shortfifo is more flexible in its placement since it is based on
-// distributed RAM
-// This one should only be used on transmit side applications.  I.e. tx_mac, tx_dsp, etc.
-//   Spartan 3's have slow routing....
-// If we REALLY need to, we could also do this on the output side, 
-// with for the receive side stuff
