An integrated circuit comprising a reduced instruction set computer (RISC)
controller to execute RISC instructions, one or more digital signal
processing (DSP) units to execute DSP instructions, and a unified
instruction pipeline coupled to the RISC controller and the one or more
DSP units, the unified instruction pipeline to decode and initiate
execution of the RISC instructions and the DSP instructions of a unified
RISC and DSP instruction set, the unified instruction pipeline to decode
and initiate the RISC instructions when the DSP instructions are
inactive, and to decode and initiate the DSP instructions when the RISC
instructions are inactive.
