Final Buffer

Each Final Buffer can store 34 packets of any size. The Final Buffer enforces buffer allocation rules that are consistent with the
RapidIO specification requirements for VC0 deadlock avoidance. The VC0 buffer allocation rules are enforced according to
packet priority only – the CRF bit is not taken into account. Buffer allocation rules control the number of free buffers at which
packets of a specific priority stop being accepted. There are two modes, controlled by the

Switch Parameters 1

.BUF_ALLOC field, as displayed in

.

The CPS-1848 supports an additional option for Final Buffer allocation. If BUF_ALLOC in the

Switch Parameters 1 Register

is

0, then FB_ALLOC in the same register provides additional options for the number of buffers free when packets of a specific
priority are no longer accepted. The options are captured in

. Under congestion, larger buffer allocations allow line rate

transfers to occur on links with high latency. However, larger buffer allocations also cause congestion to occur earlier for lower
priority packets.

The

Switch Parameters 1 Register

.BUF_ALLOC also controls buffer allocation for the Input Buffers and

Crosspoint Buffers.
