    摘要: To provide an image compression coding apparatus and method capable of minimizing a deterioration in picture quality which is caused on a reproduced image during an overflow of an output buffer. A picture top detector (7A) executes a picture top detection processing for discarding image compression data (S2) until a top of a picture of the image compression data (S2) is detected during detection of a start address, and restarts a normal operation after detecting the top of the picture. A processor (5) brings a detection start register (8) into a set state and causes the picture top detector (7A) to execute the picture top detection processing during an overflow of an output buffer (3a), and executes an interruption processing of rewriting, as a value of a write address register (9), an address where a top of an overflow picture to be a picture causing the overflow is stored.

    摘要: It is an object of the present invention to realize bypass of input data in a macro-cell such as a FIFO memory etc. to facilitate test and evaluation about other macro-cells. A bypass route (6) is provided between an input port (DI) and an output port (DO) in a FIFO memory (1) and a data bypassing selector (8) is further provided for selecting the bypass route (6) and a sense amplifier (7) of a read bit line (R.BL). Then, in the test mode, a first selector control signal (S) is set to an L level and a second selector control signal (S) of opposite phase is set to an H level. Thus, in the test mode, a data inputted from the input port (DI) is outputted from the output port (DO) by way of the bypass route (6) without via memory cells (MC1-MCX).

    摘要: When the CPU writes data into a memory, a 0 detection circuit detects the number of bits having the value 0 from the data. When the number of bits with 0 is equal to or larger than the number of bits with 1, the data output from the CPU is provided to the memory under control of a selector. When the number of bits with 0 is fewer than the number of bits with 1, the data output from the CPU is inverted and provided to the memory under control of the selector. Accordingly, the rewriting frequency of each memory cell from 0 to 1 or from 1 to 0 in the memory can be reduced in average. Thus the power consumption of the memory in a data writing mode can be reduced.

    摘要: Instructions of a program are stored at addresses sequentially designated in accordance with an M series pseudo-random number sequence in an instruction memory in the order of program addresses. A pseudo-random number program counter has a feedback shift register for generating the same M series pseudo-random number sequence and applies an address of an instruction to be read from the instruction memory to the instruction memory based on a generated pseudo-random number, and a jump address and a select signal from an instruction decoder. As a result, instructions are read from the instruction memory and executed in the order of program addresses. The feedback shift register can be implemented as a small-scale circuit and operable at high speed.

    摘要: The control circuit controls output of template block data held in the input section such that a plurality of operation units within the operation section are provided with data of unadjacent template blocks that are different from each other. The operation units within the operation section detect motion vectors according to the template block data provided thereto. Thus, motion vector detection in the template blocks except for those in a region on a display screen requiring no motion vector detection is distributed in the plurality of operation units. Accordingly, the motion vector search can be performed in a wider range in a vertical or horizontal direction than in the conventional case within the same operation time.
