Abstract: Configuration codes for implementing a plurality of circuits having different attributes are generated and stored in a memory for each task executed in a reconfigurable device. When the reconfigurable device is operated, an appropriate circuit to be executed by the reconfigurable device is selected in accordance with an operation state of the system from among a plurality of circuits having different attributes, and the configuration code for implementing the selected circuit is loaded from the memory into the reconfigurable device.

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: 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.
