摘要: A central processing unit for executing instructions of variable length in which an operand specifier for specifying the addressing mode of an operand is independent of an operation code for ascertaining the kind of an operation and the number of operands. Each operand specifier is formed of one or more data bytes, and has a stop bit flag indicating whether or not the particular operand specifier is the last operand specifier. By adding the stop bit flag, the operand specifier can be shared, and different processing can be executed with an identical operation code. In a case where, when operation code decoding means has provided an output indicative of the last operand, the stop bit flag is not detected in the corresponding operand specifier, the corresponding instruction is detected as an error.

摘要: A peripheral apparatus for image memories can communicate image data with a memory assembly composed on n blocks (60-63) of a standard-type DRAM, whether DRAM is of page mode or of nibble mode. The apparatus comprises a read data processing unit (82) sending the data of selected one among n pixels read from the DRAM blocks in parallel to an external image/graphics processor (2), a write data processing unit (84) modifying the image data taken thereinto and writing the modified data in the DRAM blocks, a feedback data (86) processing unit writing the image data now on displaying into the DRAM blocks after a desired processing again, a display data processing unit (88) sending the data read from the DRAM blocks to a monitor for display and to the external processor (2) for the feedback processing, and a control unit (80) furnishing control signals to those processing units in response to instructions from the external processor.

摘要: A high speed, multi-function and expandable image processing LSI (image signal processor) for realizing density image processing technique has been developed.
An architecture of the image signal processor (ISP) which can process a density image having 256 tones at a video rate (256 x 256 image, 6MHz, non-interlace), allows expansion of a partial operation area (kernel) and can carry out various partial neighbourhood operation, is disclosed.
The image signal processor (ISP) is a partial parallel type image processing LSI which carries out a parallel operation by using the same number of processor elements (PE's) as that of input pixel data used to produce one output pixel data.
