  • Image processing apparatus and method for efficient distribution of image processing to plurality of graphics processors
    Patent number: 6570571
    Abstract: An image processing apparatus comprising a plurality of graphics processors is disclosed. Each of the graphics processors calculates a load of its own processing on the basis of inputted and being processed graphics commands. If the load exceeds a preset specified threshold value, the graphics processor outputs a high-load signal indicating a high-load state. The image processing apparatus further comprises a command distributor. This command distributor monitors the high-load signal output from the graphics processor, prohibits transfer of the graphics commands to the graphics processor that has output the high-load signal, and then distributes the graphics commands to the other graphics processors that have output no high-load signals.
