摘要： This data processing system comprises a first data processing unit, performing processing of data under program control, a plurality of second data processing units, each performing processing of data under wired logic control, a storage unit storing the data, a first data transfer unit, connecting the first data processing unit and the second processing unit via the storage unit, and a second data transfer unit, connecting the plural second data processing units. Since the second data transfer unit, connecting the plural second data processing units operating under wired logic control are provided, the data transfer between a plurality of the second data processing units can be performed via the second data transfer unit. From the reason described above, the frequency of the data transfer via the first data transfer unit can be suppressed.

摘要： An image processing unit decodes coded data that have been coded and synthesizes the decoded moving image with graphics data. In a case where only graphics data are to be displayed, a bypass unit outputs the graphics data to a display device without use of an image processing unit. A control unit performs control of the supplying of a power supply voltage and a clock to a region containing the image processing unit and performs control of the bypass unit. If processing at the image processing unit is unnecessary, the supply of a power supply voltage or the supply of a clock to the region containing the image processing unit is stopped so as to stop the region and enable reduction of wasteful power consumption.

摘要： A variable-length-code decoding device decodes bit streams encoded in conformity with a plurality of coding systems. The device includes a decoding unit (100) decoding variable length codes encoded by the plurality of coding systems, a stream input unit (10) inputting the variable length codes, and an interface (30) interfacing the decoding unit with the stream input unit. The stream input unit and the interface are shared in the plurality of coding systems. The necessity of providing stream input units for every coding systems is removed, thereby an increase in circuit area can be suppressed. Since the interface connects the stream input unit and the decoding unit, application of this invention to other coding systems or to other combinations of coding systems is easily realized.

摘要： An encoding unit (44) individually encodes display image-forming image data, i.e., image data from an image input unit (2), decoded data from a decoding unit (46), and graphics image data from a graphics-generating unit (47). A storing unit (45) stores the individually encoded image data. As a result, when a user intends to reuse, more specifically, replay, edit, or transmit the stored display image, the user can selectively decode required image elements, thereby reusing the selectively decoded image elements. This feature provides improved user-friendliness.
