Latest Patents

Maruyama's latest patents include a "Method and apparatus for selecting the oldest queued instructions." This invention involves an instruction selector that receives M instructions per clock cycle and stores N instructions in an instruction queue memory. The instruction queue generates a precedence matrix indicative of the age of the N instructions. A dependency checker determines the available registers for executing the instructions ready for execution. The oldest-instruction selector selects the M oldest instructions responsive to the precedence matrix and the eligible queue entry signals. The instruction queue then provides the M selected instructions to execution units for execution. Upon completing the instructions, the execution units provide register availability signals to the dependency checker to release the registers used for the instructions.

Another significant patent is the "Processor structure and method for watchpoint of plural simultaneous." This invention focuses on forming time-out checkpoints based on a predetermined time-out condition or interval since the last checkpoint was formed. Such time-out conditions may include the number of instructions issued or the number of clock cycles elapsed. Time-out checkpointing limits the maximum number of instructions within a checkpoint boundary and bounds the time period for recovery from an exception condition. The processor can restore time-out based checkpointed state faster than an instruction decode based checkpoint technique in the event of an exception.
