Abstract
A microchip has a register file having a plurality of registers and an accumulator register connected in parallel with the register file that allow write operations to be performed concurrently during a single write cycle. Write operations can include write data to be written to a destination register and identification data designating a destination register. Where a first instruction designates a register in a register file and second instruction designates an accumulator register, write data from the first and second instructions can be written concurrently to the register file and the accumulator register during a single write cycle. By providing an accumulator register that is separate from the register file, data directed toward an accumulator register is diverted away from the register file and delays in performing write operations to the register file are reduced.
