ABSTRACT:
A signal processing apparatus includes the following elements. A plurality of signal processing software modules perform unit signal-processing steps of signal processing by means of software processing. An instruction input receiving unit receives an instruction. A virtual connecting unit sets up a virtual connection between inputs and outputs of the signal processing software modules in response to the received instruction. A circuit structure information storing and managing unit stores and manages the virtually connected signal processing software modules. A path routing unit routes a signal processing path to determine the order in which the stored signal processing software modules perform the signal processing. A signal processing executing unit performs the signal processing by sequentially executing the signal processing software modules in the determined order. The path routing unit determines whether a feedback loop including no delay element is generated in a circuit composed of the signal processing software modules.
