Abstract
An on-chip RAM FIFO (first-in-first-out) buffer for storing SPE overhead bytes wherein each entry of the RAM FIFO stores (1) a byte of the SPE overhead; (2) an indication of which byte of the SPE overhead is currently stored in that entry; and (3) an indication of which STS signal that byte was taken from.
