Abstract
Techniques are disclosed that relate to fusing operations for execution of certain instructions. A processor may include a first execution circuit, of a first type, coupled to a first register file, a second execution circuit, of a second type, coupled to a second register file and a load/store circuit coupled to the first and second register files. The load/store circuit includes an issue port configured to receive an instruction operation for execution, a memory execution circuit configured to execute memory access operations, and a register transfer execution circuit. The register transfer execution circuit is configured to execute instruction operations specifying data transfer from the first register file to the second register file and an operation to be performed using the data, and the load/store circuit is configured to direct a given instruction operation from the issue port to one of the memory execution circuit or the register transfer execution circuit.
