Abstract
Apparatus and methods for tracking sub-micro-operations and groups thereof are described. An integrated circuit includes a load store unit configured to receive store micro-operations cracked from a vector store instruction. The load store unit is configured to unroll multiple store sub-micro-operations from each of the store micro-operations. The load store unit includes an issue status vector to track issuance of each sub-micro-operation, an unroll status vector to track unrolling of each sub-micro-operation associated with a group of sub-micro-operations, and a replay status vector to track a replayability of sub-micro-operations associated with the group of sub-micro-operations.
