  • Method of predicting the performance of an emulated computer system
    Patent number: 5347647
    Abstract: A method and apparatus as described for predicting the performance of a computer system. A benchmark program is run on an existing host computer, and is monitored to determine the actual sequence of instructions in the instruction set of the host. These are then converted into the corresponding sequence in the instruction set of the target. The performance of the target system in executing these instructions is then determined.

  • Performance control mechanism for alternately allowing instructions to be initiated for R clock beats and preventing initiating thereof for W clock beats
    Patent number: 5159675
    Abstract: A data processor is provided with a mechanism for controlling its performance. The processor is allowed to run normally for R clock beats, and then further instruction starts are inhibited for W clock beats. The ratio W/R determines the level of performance of the processor.
