Abstract

In an embodiment, a method is disclosed that includes, comparing, during a write back stage at an execution unit, a write identifier associated with a result to be written to a register file from execution of a first instruction to a read identifier associated with a second instruction at an execution pipeline within an interleaved multi-threaded (IMT) processor having multiple execution units. When the write identifier matches the read identifier, the method further includes storing the result at a local memory of the execution unit for use by the execution unit in the subsequent read stage.
