Multiprocessor system with unit processors assigned a plurality of non-contiguous regions
First Claim
Patent Images
1. An image processor having a plurality of unit processors which are programmed to be assigned frame regions of one picture frame, said unit processors each comprising:
- a fetching unit for fetching input partial image signals corresponding to the frame regions assigned to the unit processor,a processing unit for processing the input partial image signals after all of the input partial image signals corresponding to assigned frame regions have been fetched,means for providing the processed signals to an output bus,wherein each of said unit processors is assigned a plurality of frame regions which are not contiguous to each other, andmeans for causing all the unit processors to simultaneously start processing the input partial image signals after all of the input partial image signals corresponding to the assigned frame regions have been fetched.

Abstract
An image processor has a plurality of unit processors, each of which are assigned specific non-contiguous frame regions. All of the unit processors simultaneously start processing input partial image signals after all of the signals corresponding to the assigned frame regions have been fetched.

3. An image processor comprising:
-
a plurality of unit processors, at least some of which are programmed to be assigned to a plurality of non-contiguous frame regions for each frame, each of said unit processors comprising; a fetching unit for fetching input partial image signals corresponding to the assigned non-contiguous frame regions; a processing unit for processing the input partial image signals after all of the input partial image signals corresponding to assigned frame regions have been fetched, and means for outputting the processed input partial image signals. - View Dependent Claims (4, 5, 6)

7. A method for processing an image frame with a processor having a plurality of unit processors, the frame having frame regions, wherein each of the unit processors has a memory for storing a program which includes information concerning which frame regions are assigned to which unit processor, said method comprising the following steps:
-
assigning a plurality of non-contiguous frame regions to at least some of the unit processors by storing information concerning which frame regions are assigned to the unit processors in the memories of the unit processors; fetching input signals corresponding to the plurality of frame regions; processing each of the frame regions, after all of the input signals corresponding to the frame regions assigned to a unit processor have been fetched, resulting in processed signals; and outputting the processed signals. - View Dependent Claims (8)
