Abstract: An array type processor comprises a data path unit to execute processing, and a state management unit to control the state of the data path unit in accordance with a command that specifies processing on the data.

The input DMA circuit first transfers the command to the state management unit, and then transfers the data to be processed to the data path unit.

Abstract: An array-type computer processor stops, with a plurality of computer programs held, a state control unit and a data-path unit, upon input of event data for task switching. The array-type computer processor obtains the operation state of the state control unit and the processed data of the data-path unit when stopped, and temporarily holds them for each of a plurality of the computer programs. Upon completion of this, the array-type computer processor reads the operation state and processed data of any other computer program and sets them in the state control unit and data-path unit. Upon completion of this, the array-type computer processor outputs to the state control unit the event data for starting the operation. The state control unit then starts to sequentially transfer the operation state, thereby making it possible to perform the process operations according to a plurality of computer programs in a time-sharing manner.

Abstract: In a plural line buffer type memory LSI, a line selection register 16 (holding an address for designating a line buffer) is added. The value of the line selection register 16 is previously updated by a memory access instruction having a room in an address. Thus, it is possible to maintain compatibility with input/output terminals of a general purpose memory LSI, or to prevent the increase in the number of input/output terminals, and also to prevent the increase of the memory access delay attributable to the restriction in connection with the issue of the commands. Accordingly, it is possible to maintain the compatibility with the general purpose memory LSI having no line buffer, or alternatively to prevent the increase of the memory access delay attributable to a restriction in an interval for issuing the commands.

Abstract: An arrayed processor has a plurality of processing elements each having a plurality of types of arithmetic logic units for processing data having different numbers of bits from one another. The arrayed processor divides a series of processing data of various numbers of bits supplied from an external circuit into data of more bits and data of fewer bits. These data are processed in parallel by the arithmetic logic units of the processing elements. The efficiency of arrayed processor can be increased, since small-scale processing operations are individually performed by the processing elements and connections between the processing elements are made according to object codes.
