Information processing system, integrated information processing system, method for calculating execution load, and computer program
First Claim
1. An information processing system, comprising:
- a processor operable to carry out predetermined information processing;
a signal producing unit operable to produce an execution enabling signal for causing said processor to carry out said predetermined information processing; and
a load determination unit operable to determine an execution load associated with said predetermined information processing;
said processor being operable to begin execution of said predetermined information processing in response to receipt of said execution enabling signal and to produce an execution termination signal upon completion of said predetermined information processing, said execution termination signal representing said completion of said predetermined information processing;
said load determination unit being operable to begin determination of said execution load in response to receipt of said execution enabling signal and to terminate said determination of said execution load in response to receipt of said execution termination signal.

Abstract
A graphics processing system includes a graphics processor for carrying out image processing, a control processor for use in producing a draw ready signal to enable the image processing, and a time counter for use in determining a process time for the image processing. The graphics processor begins execution of the image processing in response to the reception of the draw ready signal and produces a draw complete signal upon completion of the image processing. The draw complete signal represents the completion of the image processing. The time counter begins determination of the execution load on the processor in response to the reception of the draw ready signal and terminates the determination in response to the reception of the draw complete signal. This makes it possible to determine the process time from the beginning to the end of the image processing.
