ABSTRACT:
A digital signal processor that includes an instruction memory, a program control unit, and an instruction decoder. The instruction memory stores a sequence of instruction words including DSP instruction words and RISC instruction words. The program control unit outputs an instruction address to the instruction memory so as to select one instruction word in the instruction memory. Every DSP instruction word identifies one data processing operation and one data transfer operation to be performed. The DSP instruction words include a predefined DSP instruction word having separate source and destination fields for specifying register locations for data sources and data destinations. The RISC instruction words include a predefined RISC instruction word corresponding to the predefined DSP instruction word. The predefined RISC instruction word has separate source and destination fields for specifying register locations for data sources and data destinations. One of the source and destination fields in the predefined RISC instruction word has more bits than the corresponding field in the predefined DSP instruction word. The instruction decoder decodes the selected instruction.
