(bit 35) constituting the entire packet. A packet can be any length the user desires,
up to the total available memory in the multi-queue device. The device monitors
the SOP (bit 34) and looks for the word that contains the EOP (bit 35). The read
port is supplied with an additional status flag, “Packet Ready”. The Packet Ready
(PR) flag in conjunction with Empty Flag or Output Ready flag (EF/OR)
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 (IDT STANDARD MODE)
connected in a parallel bus configuration as indicated in Figure 67, Expansion
using ID codes, and Figure 68, Expansion using WCS / RCS providing both
depth expansion and/or queue expansion. Expansion of devices is supported
only in IDT Standard mode. Depth Expansion means expanding the depths of

Expansion of multi-queue devices is also possible. Up to 8 devices can be

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 a fewer number
of queues to increase the depth of each queue. For example, depth expansion
of 8 devices provides the possibility of 8 queues of 4096K bits, 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.
may be setup, with a average of each queue being 16,384K x36 deep using
8 devices, each with 8 queues. If fewer queues are desired, then more memory
blocks will be available to increase queue depths if desired. When connecting
multi-queue devices in expansion configuration all respective input pins (data
& control) and output pins (data & flags), should be “connected” together
between individual devices. Refer to Figure 67, Expansion using ID codes, and
Figure 68, Expansion using WCS / RCS for device connection details.
For queue expansion a maximum number of 256 queues (32 x 8 queues)
