Device and method for processing instructions based on masked register group size information

摘要

A method and a device for processing instructions based on register group size information includes a pipelined processor, an instruction memory unit and a register file, whereas the pipelined processor includes a write-back unit and an execution unit. The device is characterized by including a controller that is adapted to receive a first register group size information and a first register identification information that define a first group of source registers associated with a first instruction; and to determine an execution related operation of the first instruction in response to the first register group size information, the first register identification information, a second register group size information and a second register identification information. The second register group size information and the second register identification information define a second group of target registers associated with a second instruction. The second instruction is provided to the pipelined processor before the first instruction.
