Abstract
An apparatus for use in image processing is set forth that comprises a pixel processor, context memory, and a context memory controller. The pixel processor is adapted to execute a pixel processing operation on a target pixel using a context of the target pixel. The context memory is adapted to store context values associated with the target pixel. The context memory controller may be adapted to control communication of context values between the pixel processor and the context memory. Further, the context memory controller may be responsive to a context initialization signal or the like provided by the pixel processor to initialize the content of the context memory to a known state, even before the pixel processor has completed its image processing operations and/or immediately after completion of its image processing operations. In one embodiment, the pixel processor executes a JBIG coding operation on the target pixel.
