Abstract
An operation processing apparatus includes an operation executing unit having a first input connected to one end of a circular pipeline and a second input to which the operation result of a preceding feedback loop process is provided. The operation execution unit responds to an input of a data packet including a feedback loop process instruction for continuously executing multiplication and adding operations with respect to an operand included in the input data packet and an operand provided from the second input to provide the multiplication result to the other end of the circular pipeline. The operation processing apparatus further includes an operation result holding unit responsive to a supplied hold timing signal for holding an adding result of the operation execution unit for providing the same to the second input at the time of executing a subsequent feedback loop process, and a synchronization control unit for controlling synchronization of the operation execution of the operation executing unit and the operation of the operation result holding unit.
