IDT72V51436/72V51446/72V51456 3.3V, MULTI-QUEUE FLOW-CONTROL DEVICES

one packet is available to read. When in packet mode the almost empty flag
status, provides packet ready flag status for individual queues.
EXPANSION
Expansion of multi-queue devices is also possible, up to 8 devices can be
connectedinaparallelfashionprovidingthepossibilityofbothdepthexpansion
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
possibilityof8queuesof64Kx36deep,eachqueuebeingsetupwithinasingle
device utilizing all memory blocks available to produce a single queue. This is
the deepest queue that can setup within a device.
For queue expansion a maximum number of 128 (8 x 16) queues may 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
morememoryblockswillbeavailabletoincreasequeuedepthsifdesired.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.
