摘要
A microprocessor including an instruction decode unit configured to detect a DSP call instruction is provided. The DSP call instruction is indicative of a call to a subroutine which performs a DSP function. Detected DSP call instructions are routed to a DSP which executes a routing performing the corresponding function. Subsequent to the DSP completing execution of the routine, the microprocessor continues execution at the instruction subsequent to the DSP call instruction. If a DSP is not included in the computer system, the DSP call instruction is executed in a manner similar to a subroutine call instruction. The microprocessor subsequently executes a corresponding routine which performs the DSP function.
