Abstract
The invention relates to a signal processor to be built into a controller or the like for receiving various input signals and generating control signals according to the input signals. The signal processor includes an internal bus interconnecting various components of the signal processor. The invention also includes a first input-output controller for controlling the application of input signals to the signal processor and the output of control signals from the signal processor. The first input-output controller operates under the control of a switch in which the switching criteria for the switch is whether or not the signal processor is using its internal bus. Accordingly, the first input-output controller is allowed access to the signal processor depending on whether or not the internal bus of the signal processor is being used.
