Abstract
PURPOSE:To execute an operation processing at a high speed, by effectively utilizing plural product sum calculating circuits, and executing in parallel a data transfer and an operation required for the calculation processing. CONSTITUTION:A memory 1 stores and holds a convolution function required for a convolution operation, and a memory 2 stores an input data to be provided to this calculation. A function data of the memory 1 is read out to a register 41 under the control of a controller 3, and after that, is transferred in order to registers 42...4l cascaded with the register 41. Also, an input data of the memory 2 is read out in order in accordance with read-out of the function data, is stored and held in a register 5, and after that, is supplied in parallel to product sum calculating circuit 61...6l provided in accordance with the registers 41...4l, the input data and the convolution function are integrated, are added to the previous data, and the product sum value is read out in the memory 2.
