Abstract
A method of operating a circuit is disclosed. The method generally comprises the steps of (A) generating a particular policy of a plurality of policies by a lookup operation on a first transaction request received by the circuit, (B) generating a second transaction request for use by a memory external to the circuit based upon the first transaction request and the particular policy in response to a first cache signal of the first transaction request having a non-cacheable state and (C) searching a plurality of address tags for cache data cached within the circuit for a match with the first transaction request in response to the first cache signal having a cacheable state.
