NOTE:
1. Cascading the FIFOs in word width is done by ANDing the IR and OR as shown in Figure 13.
NOTE:
1. FIFOs are expandable in width. However, in forming wider words two external gates are required to generate composite Input and Output Ready flags. This requirement

64 x 5
is due to the different fall-through times of the FIFOs.
