Data Cache Victim Buffer
‹ The
victim buffer is used to read a dirty cache line either
being flushed or replaced by a cache line fill and then to
initiate a burst write operation on the bus to perform the line
copyback to the system.
‹ The processor can continue running without having to wait
for the data to be written back to L2 memory.
‹ The victim buffer is comprised of a 4-deep FIFO each 64-bits
in width (similar to the fill-buffer.)
‹ There is no data forwarding support from the victim buffer.
