port is supplied with an additional status flag, “Packet Ready”. The Packet
Ready (PR) flag in conjunction with Output Valid (OV) indicates when at least
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

Expansion of multi-queue devices is also possible, up to 8 devices can be
6
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
possibility of 8 queues of 64K x36 deep, each queue being setup within a single
device utilizing all memory blocks available to produce a single queue. This is
the deepest queue that can setup within a device.
setup, each queue being 2K x36 deep, 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 256 (8 x 32) queues may be
