  • Analysis of the performance of a portion of a data processing system
    Patent number: 7110934
    Abstract: The present invention provides a system and method for controlling a simulator to run a software simulation of a data processing system in order to generate simulated timing data indicative of performance of an unmodelled portion of the data processing system not modelled by the software simulation. The software simulation provides a timing accurate model of those parts of the data processing system other than the unmodelled portion. The method of the invention comprises inputting to a controller of the simulator real trace data obtained from execution of a program by the data processing system, the real trace data identifying the sequence of instructions executed by the data processing system, and associated timing data.
