Abstract
An image data encoding/decoding device has a memory for parallel data input/output, a data input unit, a data output unit, an encoding unit, a decoding unit, and a memory control unit. Separate encoding and decoding units are employed to ensure efficient encoding/decoding operations. The image data are handled in serial form in the input, output, encoding and decoding units and in parallel form only at the input to or output from the memory, so that these units can effect simultaneous parallel functions in mutually independent manner. Also, efficient access to the memory is ensured by the memory control unit, which handles simultaneous requests for access from various units according to a predetermined order of priority.
