Abstract
A processor that includes a register file, a latency shifter, a decode unit and a plurality of functional units is introduced. The register file includes a write port. The latency shifter includes a plurality of shifter entries and shifts out a shifter entry among the shifter entries every clock cycle. Each of the shifter entries is associated with a clock cycle and each of shifter entries includes a writeback value that indicates whether the write port of the register file is available for a writeback operation in the associated clock cycles. The decode unit is configured to decode an instruction and issue the instruction according to the writeback value of the latency shifter. The functional units are coupled to the decode unit and the register file and are configured to execute the instruction issued by the decode unit and perform writeback operation to the write port of the register file.
