    摘要: An image processing apparatus has: a data memory configured to store image data; an RP register configured to hold a two-dimensional address indicating a position of an RP in a frame of image data; and an RP control section configured to control the two-dimensional address held by the RP register on the basis of the width and height of the frame. Furthermore, the image processing apparatus has an address calculation unit configured to, when reading target pixel data is read from the data memory on the basis of an instruction code provided with a field for specifying a two-dimensional relative position from the RP by a combination of two immediate values, calculate an address at which the reading target pixel data is stored, on the basis of the two-dimensional address, the combination of immediate values and the width of the frame.

    摘要: A memory controller controls a memory access to each memory region out of one or more memory regions in SIMD unit. The memory controller includes: a pointer-calculation hardware unit that increments by unit SIMD a value of an access control pointer corresponding to each of the memory regions at different timings corresponding to an access mode set beforehand in each memory region; and a memory-access-control hardware unit that calculates an access destination address in each of the memory regions based on a value of an access control pointer in the memory region, and causes a memory access in SIMD unit to be performed to the calculated access destination address.

    摘要: A moving picture processor includes a first detector configured to detect a reference block most similar to a target block for which motion is to be detected and which is set in a current picture, and to generate a first motion vector candidate indicating a relative position between the target block and the reference block. A second detector is configured to detect a first reference area most similar to a first target area obtained by combining the target block and a first adjacent block adjacent to the target block, and to generate a second motion vector candidate indicating a relative position between the first target area and the first reference area. A determination circuit is configured to determine a motion vector for the target block, based on the first and second motion vector candidates.
