Abstract
A plurality of processing elements are connected in cascade so as to constitute a single signal processing apparatus. The signal processing apparatus has a first path for transferring an input data signal and a second path for transferring a processing result of the input data signal. Each of the processing elements has a first input disposed on the first path, a data holding circuit for holding the data signal supplied through the first input, a product-sum circuit for executing a product-sum operation between the data signal held in the data holding circuit and another data signal, a second input disposed on the second path so as to supply the other data signal to the product-sum circuit, a result register for holding the result of the operation calculated by the product-sum circuit and supplying the held result of the operation to the second path, an output selecting circuit for supplying either one of the data signal held in the data holding circuit and the result of the operation held in the result register, and a processing control circuit for controlling respective operations of the data holding circuit, product-sum circuit, result register, and output selecting circuit. Since a route extending from the result register to the output selecting circuit forms a bypass from the second path to the first path, a flexible process can be performed by the signal processing apparatus by using or not using the bypass depending on control information.
