Basically DSP processing (or any other processing) on x86 hardware is a mere achievment of brute force within a processor architecture that was seriasly flawed when it first emerged some 20 years ago and has only gotten worse since, in the name of backwards compatibility.
Just consider that in Real Mode, an intel processor uses two 16 bit registers to form a 20 bit address(!). And the people behind that design have managed to become the biggest player in the processor market(!).
