is time available for the PNX1300 to pack and unpack the
words. At three PCI-XIO bus wait states, at least 120
nanoseconds are required for each byte transferred. This
corresponds to 12 CPU instructions at 100 MHz. The
CPU may need to process each byte of data anyway. In
the case of ROMs and flash EPROMs, the data is typical-
ly compressed, requiring the PNX1300 CPU to both un-
pack and decompress the data.
