  • Apparatus and methods for forward error correction decoding
    Patent number: 7159169
    Abstract: An apparatus includes an instruction decoder, at least one control register coupled to the instruction decoder, and an add-compare-select (ACS) engine coupled to the at least one control register. The instruction decoder is operative to control the ACS engine to perform Viterbi decoding in response to the instruction decoder receiving a first instruction, and is operative to control the ACS engine to perform turbo decoding in response to the instruction decoder receiving a second instruction.

  • Method and circuit for preloading prediction circuits in microprocessors
    Patent number: 6397326
    Abstract: A method and circuit is provided for preloading a branch prediction unit within a microprocessor. In one embodiment of the method, a branch history storage device such as branch history shift register is written with a predetermined multibit predicter in response to the microprocessor receiving and executing a special write branch history storage device instruction for writing the predetermined multibit predicter into the branch history storage device. The branch history storage device is contained within a prediction circuit of the microprocessor, and generally the contents of the branch history storage device is used in the process of predicting the results of executing conditional branch instructions prior to their execution.
