Abstract
Apparatus and methods for processing of a vector load or store micro-operation with mask information as a no-operation (no-op) when a mask vector for the vector load or store micro-operation has all inactive mask elements or processing vector load or store sub-micro-operation(s) with active mask element(s) are described. An integrated circuit includes a load store unit configured to receive load or store micro-operations cracked from a vector load or store operation, determine that a mask vector for the vector load or store micro-operation is fully inactive, and process the vector load or store micro-operation as a no-operation. If the mask vector is not fully inactive, the vector load or store micro-operation is unrolled into vector load or store sub-micro-operation(s) which have active mask element(s). Vector load or store sub-micro-operation(s) which have inactive mask element(s) are ignored.
