Information processing apparatus, control method thereof, and non-transitory computer-readable storage medium

An information processing apparatus comprising:

• a programmable circuit including a plurality of 2-input 1-output ALUs (Arithmetic and Logic Units);
• and
• an updating unit configured to update the programmable circuit in accordance with circuit information set at a set timing,
• wherein each of the ALUs in the programmable circuit includes
• a selector configured to select two input data corresponding to setting out of a plurality of input data including a preset fixed value, and
• a calculation unit configured to perform a set type of calculation for two data selected by the selector,
• wherein the updating unit sets, for an ALU which is not used in the programmable circuit, that the selector selects the fixed value.

A method of controlling an information processing apparatus including a programmable circuit including a plurality of 2-input 1-output ALUs (Arithmetic and Logic Units), the method comprising:

• updating the programmable circuit in accordance with circuit information set at a set timing,
• wherein each of the ALUs in the programmable circuit includes
• a calculation unit configured to perform a set type of calculation for two data and output a calculation result,
• a delay unit configured to delay the two input data in accordance with delay amounts independently set and supply the delayed data to the calculation unit, and
• a controller configured to control a delay amount for the delay unit and a calculation timing for the calculation unit in accordance with externally set information, and
• wherein in the updating, clock gating start timings for a plurality of delay elements of the delay unit are set if an ALU of interest as a first processing circuit in the programmable circuit inputs final data to be processed.

A non-transitory computer-readable storage medium storing a program which, when read and executed by a computer including a programmable circuit including a plurality of 2-input 1-output ALUs (Arithmetic and Logic Units), causes the computer to perform the step of a method of controlling an information processing apparatus, the method comprising:

• updating the programmable circuit in accordance with circuit information set at a set timing,
• wherein each of the ALUs in the programmable circuit includes
• a calculation unit configured to perform a set type of calculation for two data and output a calculation result,
• a delay unit configured to delay the two input data in accordance with delay amounts independently set and supply the delayed data to the calculation unit, and
• a controller configured to control a delay amount for the delay unit and a calculation timing for the calculation unit in accordance with externally set information, and
• wherein in the updating, clock gating start timings for a plurality of delay elements of the delay unit are set if an ALU of interest as a first processing circuit in the programmable circuit inputs final data to be processed.
