Abstract
A request routing circuit includes m inputs for receiving m input request signals and n outputs for outputting a set of n output request signals. A routing subsystem within the request routing circuit is provided between the m inputs and the n outputs and comprises k inputs and n outputs, where m is greater than k, and where the routing subsystem is configured to operate over a plurality (m/k, rounded up to the next integer) of cycles to provide the set of n output request signals based on the m inputs to the n outputs.
Claims20
A request routing arrangement, comprising:
- m inputs configured to receive m input request signals;
- n outputs configured to output a set of n output request signals;
- and
- a routing subsystem provided between the m inputs and the n outputs and comprising k inputs and n outputs, where m is greater than k, the routing subsystem configured to operate over a plurality of cycles to provide the set of n output request signals to the n outputs.
A method for routing requests, the method comprising:
- receiving, by a request routing circuit, m input request signals;
- operating the request routing circuit over a plurality of cycles to provide a set of n output request signals, wherein k of the m input request signals are routed during each of the cycles, where m is greater than k;
- and
- outputting at the end of the plurality of cycles the set of n output request signals to a processing unit.
