System including programmable integrated circuit including first areas having same shape and second areas formed between first areas, and operation processing device and method for controlling the programmable integrated circuit

A system comprising:

• a programmable integrated circuit capable of arbitrarily changing an internal circuit configuration and including, as an operational circuit resource, a plurality of first areas each of which has the same shape and a plurality of second areas formed between the plurality of first areas;
• and
• a processor configured to:
• recognize a first request of a first operation which is executed by the programmable integrated circuit,
• check whether a not-written operational circuit resource which is not rewritten by another operational circuit after initially being written to for generating a first operational circuit exists in the operational circuit resource;
• select, when the not-written operational circuit resource exists, a third area corresponding to the second areas and a fourth area corresponding to the first areas which are used for the first operation from the not-written operational circuit resource,
• set second configuration information to the selected third area to generate the first operational circuit,
• cause the generated first operational circuit to execute the first operation,
• after the first operation is completed, cause the third area included in the first operational circuit to function as a communication path which is used by a second operational circuit other than the first operational circuit to transmit and receive data to and from another operational circuit or an external interface, check, when the not-written operational circuit resource does not exist, whether a not-used operational circuit resource which is not used by another operational circuit exists in the operational circuit resource,
• select, when the not-used operational circuit resource exists, the third area corresponding to the second areas and the fourth area corresponding to the first areas which are used for the first operation from the not-used operational circuit resource,
• set the second configuration information and first configuration information to the selected third area and the selected fourth area, respectively, to generate the first operational circuit,
• cause the generated first operational circuit to execute the first operation,
• after the first operation is completed, cause the third area included in the first operational circuit to function as a communication path which is used by the second operational circuit to transmit and receive data to and from the another operational circuit or the external interface, and
• cause, when the not-used operational circuit resource does not exist, a central processing unit (CPU) to execute the first operation.
