摘要： A variable-length code decoding apparatus that decodes a bitstream includes: a storage unit that stores a variable-length code table; a bitstream cutout unit that outputs a bit string of a fixed length; a reference unit that outputs decoded data and a code length with reference to the storage unit; a determination unit that determines whether a bit string of the fixed length is accumulated; a determination unit that determines whether a bit string of a length that is shorter than the fixed length is accumulated; and a selection unit that selects one of the determination results from the determination units. The bitstream cutout unit sets a starting bit based on the selected determination result, and the selection unit switches the selection of the determination results from the determination units.

摘要： An image memory access control unit (502) judges whether or not an additional pixel required for motion compensation is necessary, the additional pixel not being included in a plurality of pixels forming an image shown by a reference block. When the additional pixel is judged to be necessary, a yet-to-be-obtained-pixel interpolating unit (503) generates at least one additional pixel, and generates a reference image to be used for motion compensation using the generated at least one additional pixel and at least a part of the image shown by the reference block. When the additional pixel is judged to be unnecessary, the yet-to-be-obtained-pixel interpolating unit (503) outputs at least a part of the image shown by the reference block as the reference image.

摘要： A mechanism of making a low standby current caused by power off compatible with a fast return operation from a standby caused by an interrupt is realized. An information processing device has a first area that includes a central processing unit and peripheral circuit modules, a second area having information holding circuits for holding values of registers contained in the peripheral circuit modules, and a first power switch for controlling supply of a current to the first area. When the information processing device operates in a first mode, an operating current is supplied to the first area and the second area. When the information processing device operates in a second mode, the first power switch is controlled so that the supply of the current to the first area can be shut off, and the supply of the current to the second area is continued.

摘要： A data processor having: an instruction fetch unit for acquiring an instruction; and an instruction execution unit for execution, by pipeline processing, the instruction acquired by the instruction fetch unit. In the data processor, the instruction execution unit includes an execution pipeline pipelined into two or more stages for execution of the execution instruction, and an execution pipeline control unit capable of changing a stage to arrange an operation by the execution unit in according to the number of wait cycles until data required for execution of the execution instruction is fixed. The stage, where an operation by the execution unit is arranged, is changed according to the number of wait cycles until the data is fixed, whereby the number of input-fixing wait cycles increased by pipelining cache access can be reduced.
