Abstract:
1. An apparatus for use in image processing comprising: a pixel processor adapted to determine whether a context of a target pixel of an image is valid and to process the target pixel using the context of the target pixel if the context is valid; context memory adapted to store one or more context values associated with the target pixel; and a context memory controller responsive to a context initialization signal provided by the pixel processor to initialize all memory locations of the context memory to a same initialization state when the pixel processor determines that the context values are not valid, wherein the initialization state corresponds to a context memory state that enables the pixel processor to begin encoding or decoding operations of a new image, wherein the pixel processor is configured to perform other encoding or decoding operations while the context memory controller initializes the context memory, and wherein the pixel processor is configured to read and write the context values from and to the context memory.
