摘要： A processor array includes element processors which are arranged in a matrix in correspondence to respective pixels of a template block, which is a current picture image pixel block. Each element processor stores pixel data of a search window block, which is a corresponding reference picture image pixel block, and obtains an evaluation function value component with respect to the template block pixel data. A summing part sorts the evaluation function components received from the respective element processors of the processor array in accordance with a plurality of predictive modes and sums up the components for the respective sorts, for forming evaluation function values for the respective predictive modes. A comparison part compares the evaluation function values received from the summing part for each predictive mode, to decide a displacement vector providing the best similarity as a motion vector for each predictive mode. It is possible to simultaneously detect motion vectors according to a plurality of predictive modes. It is possible to detect motion vectors employed for moving image predictive compensation in accordance with a plurality of predictive modes at a high speed with a small hardware volume.

摘要： An SRAM adapted for changing the sequence of data. A counter 7 generates a sequentially increasing address signal. A write designation circuit 2a sequentially designates a memory cell row to be selected for writing in response to the address signal. Conversely, a read designation circuit 3a designates a memory cell row in response to the address signal in a sequence determined by a predetermined rule. The generation of an address signal, which changes in a complicated manner and is required for changing the sequence of data, is not required, so that the amount of the operation process by the CPU is decreased.

摘要： A data bus has a bit length of 2 words, and is divided into two bit groups, each of which corresponds to one word. Therefore, the data bus can simultaneously transfer data of two words. A register, a data operation part of a CPU, a RAM and a ROM is connected to the data bus. Even if there is generated data of two words to be transferred in these registers, the data operation part, the RAM and the ROM, the data bus can simultaneously transfer the data. In order to prevent conflict of data on the data bus, there are provided a bus driver, a multiplexer and a bus selector.
