Processing device, array-type processing device, control method thereof, and information processing system

A processing device comprising:

• a plurality of processing elements to which processes according to setting data are configured to be assigned;
• a connection element configured to provide a connection environment according to the setting data to said plurality of processing elements;
• a supply unit configured to detect completion of processing according to first setting data in said plurality of processing elements, and to supply second setting data to said processing elements and said connection element in response to detection;
• and
• a control unit configured to control a power supply voltage to be supplied to a processing unit including said plurality of processing elements and said connection element, and to a controller including said supply unit.

A processing device, which includes a plurality of first domains, a power supply to which is controllable, and a second domain to which the power supply is always supplied, said device comprising:

• a plurality of processing units which are allocated in the first domain, and each of which includes a plurality of processing elements and a router configured to control connections between the plurality of processing elements;
• a supply unit configured to supply configuration information to the processing device, said supply unit being allocated in the second domain;
• and
• a power supply control unit configured to control the power supply to the processing device, said power supply control unit being allocated in the second domain.

An information processing system comprising:

• an array-type processing device which includes a first domain, a power supply to which is controllable, and a second domain to which the power supply is always supplied, said device comprising:
• a plurality of processing units which are allocated in the first domain, and each of which includes a plurality of processing elements and a router configured to control connections between the plurality of processing elements;
• a configuration information supply unit configured to supply configuration information to one or more processing units of said plurality of processing units, said configuration information supply unit being allocated in the second domain;
• and
• a power supply control unit configured to control the power supply to said plurality of processing units, said power supply control unit being allocated in the second domain,
• wherein said configuration information supply unit comprises:
• a holding unit configured to externally receive configuration information and to hold the configuration information;
• a selection unit configured to select one configuration information from pieces of configuration information held by said holding unit;
• and
• a supply unit configured to supply the configuration information selected by said selection unit to one or more processing units which use the configuration information, and
• when processing in said array-type processing device is switched from processing using first configuration information to processing using second configuration information, said holding unit externally receives and holds the second configuration information before completion of the processing using the first configuration information, said power supply control unit controls the power supply so as to stably supply the power supply to one or more processing units used by the second configuration information before completion of the processing using the first configuration information, and said selection unit selects the second configuration information in response to completion of the processing using the first configuration information;
• a transmission unit configured to transmit configuration information to said holding unit;
• a detection unit configured to detect an execution state of processing by said plurality of processing units;
• and
• a selection control unit configured to transmit a signal, which instructs to select the second configuration information, to said selection unit in response to completion of processing using the first configuration information detected by said detection unit.

A control method of an array-type processing device, which includes a first domain, a power supply to which is controllable, and a second domain to which the power supply is always supplied, the array-type processing device comprising:

• a plurality of processing units which are allocated in the first domain, and each of which includes a plurality of processing elements and a router configured to control connections between the plurality of processing elements;
• a configuration information supply unit configured to supply configuration information to one or more processing units of the plurality of processing units, the configuration information supply unit being allocated in the second domain;
• and a power supply control unit configured to control the power supply to the plurality of processing units, the power supply control unit being allocated in the second domain,
• the configuration information supply unit comprising:
• a holding unit configured to externally receive configuration information and to hold the configuration information;
• a selection unit configured to select one configuration information from pieces of configuration information held by the holding unit;
• and a supply unit configured to supply the configuration information selected by the selection unit to one or more processing units which use the configuration information,
• when processing in the array-type processing device is switched from processing using first configuration information to processing using second configuration information, the control method comprising:
• controlling the holding unit to externally receive and hold the second configuration information before completion of the processing using the first configuration information;
• controlling the power supply control unit to control the power supply so as to stably supply the power supply to one or more processing units used by the second configuration information before completion of the processing using the first configuration information;
• and
• controlling the selection unit to select the second configuration information in response to completion of the processing using the first configuration information.
