one packet is available to read. When in packet mode the almost empty flag
status, provides packet ready flag status for individual queues.
EXPANSION
connected in a parallel fashion providing the possibility of both depth expansion
or queue expansion. Depth Expansion means expanding the depths of
individual queues. Queue expansion means increasing the total number of
queues available. Depth expansion is possible by virtue of the fact that more
memory blocks within a multi-queue device can be allocated to increase the
depth of a queue. For example, depth expansion of 8 devices provides the

(16 QUEUES) 36 BIT WIDE CONFIGURATION 589,824, 1,179,648 and 2,359,296 bits
Expansion of multi-queue devices is also possible, up to 8 devices can be

setup, each queue being 1K x 36, 2K x 36K, x 36 for the IDT72V51436,
IDT72V51446 and IDT72V51456 respectively. If less queues are setup, then
more memory blocks will be available to increase queue depths if desired. When
connecting multi-queue devices in expansion mode all respective input pins
(data & control) and output pins (data & flags), should be “connected” together
between individual devices.
For queue expansion a maximum number of 128 (8 x 16) queues may be
