The specified lookup rate is accurate. The LOOKUP_INTERFACE_FREQ must be equal to the LOOKUP_RATE. A higher LOOKUP_INTERFACE_FREQ has no effect on performance. No management
requests are served until the Lookup Request FIFO is cleared. ECC scrubbing takes
place only when both the Lookup Request FIFO and the Management Request FIFO are
emptied. The management request rate value in such cases is more than or equal to
the following value:
Management Request Rate = RAM_FREQ -
LOOKUP_RATE*TDM_FACTOR
The ECC scrubbing process has the lowest priority. Neither the lookup throughput nor the Management Request throughputs are affected.
