| description | An electronic image processing apparatus having image processing resources including a controller for directing the operation of the image processing resources, the controller including a disk memory, the method of controlling mass memory device bandwidth access during an access time window including guaranteeing access to the memory for predetermined time periods for a first set of image processing resources during each access time window, a second set of image processing resources having access subordinate to the first set of image processing resources, maintaining a record of mass memory device access for the first set of image processing resources during each access time window, receiving a memory access request from the first set of image processing resources, determining that said resource utilization does not exceed the predetermined time period, and allowing current access to the mass memory device by the image processing resource. The second set of image processing resources achieves access upon determination that none of the first set of resources is requesting access or upon determination that each of the first set of resources has exceeded the predetermined time period. |
