ABSTRACT:
A digital signal controller is provided having modular operation. Specifically, the digital signal controller includes a sequence control unit and a sequencer for producing a sequence of macro instructions and a sequence of micro instructions, respectively. Changes in the number or order of macro instructions may not require changes to the number and order of micro instructions and vice versa. As such, changes in macro instructions can occur by modifying the sequence control unit and possibly the decoder without necessarily changing the sequencer. Changes in the number and order of micro instructions requires changes in the sequencer and possibly the decoder without necessarily changing the sequence control unit. The aforementioned modular technique of forwarding macro and micro instructions to a decoder for controlling an execution unit arranged between an analog interface unit and a DSP allows variability in the operation of the DSP, as well as variability in the design implementation of changes to the digital signal controller.
