Abstract: Based on a constriction condition of a parallel operation device which has been previously registered with data, a data processing device extracts a loop structure from a single-layer state transition graph structure of an object code input thereto, and converts the state transition graph containing a loop structure into a state transition on another layer, which is then output as a new object code.

Abstract: An array-type computer processor including a data path unit communicating with a state control unit obtains data of a predetermined number of cooperative partial instruction codes, and operates with temporarily holding only a predetermined number of data-obtained instruction codes comprising cooperative partial instruction codes corresponding to contexts and operation states for the data path unit and the state control unit, respectively, from an external program memory which stores data of a computer program.

Abstract: In data path means, processor elements individually execute data processing in accordance with command codes described in a computer program, and switching elements individually control a connection relationship to switch among a plurality of processor elements in accordance with the command codes. When an access to an external memory is made from the data path means, slave memory means generates event data indicative of a task change while temporarily holding access information for executing the access with a delay, and executes the access in place of the data path means. Task changing means changes a task to be executed by the data path means when event data indicative of a task change is generated by the slave memory means.

Abstract: An application program is executed and is easily made reusable by dividing the application program into processing units, and by creating a logical circuit in the reconfigurable hardware by switching so as to improve the processing speed at low cost.

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: An array-type computer processor obtains data of a predetermined number of cooperative partial instruction codes, and operates with temporarily holding only a predetermined number of data-obtained instruction codes, from an external program memory which stores data of a computer program. Every time the operations with the temporarily-held instruction codes are complete, the subsequent instruction codes are data obtained, so that the operation according to a computer program can be performed even if the data volume of the computer program is over the storage capacity.
