Abstract: A method and an apparatus for bus encoding and a method and an apparatus for bus decoding are provided. The methods and apparatuses for bus encoding/decoding use a discontinuous pattern table (DPT) to store discontinuous pattern pairs. The tables are kept synchronous in both transmitter and receiver ends. After transmitting the first data in a discontinuous pattern pair, the second data may be transmitted by merely informing the receiver end through a control line instead of transmitting the second data by the bus.

Abstract: A system and method for unnecessary dynamic branch prediction elimination in a processor with a dynamic branch predictor, includes a branch distance generation module for generating a branch distance between two consecutive branch instructions, a branch distance table for storing the branch distance generated by the branch distance generation module, and a dynamic branch predictor enabling module for determining enable or disable the dynamic branch prediction by using the branch distances stored in the branch distance table for the next incoming instructions. Through the configuration of the system, the dynamic branch prediction is performed only for branch instruction, so as to save power consumption due to unnecessary dynamic branch predictions.
