DIGITAL SIGNAL PROCESSORS VS. UNIVERSAL MICROPROCESSORS

Digital Signal Processors have approximately the same level of integration, the same clock frequencies as general purpose microprocessors. Even usually general purpose microprocessors have advantage in these fields. But on signal processing tasks DSPs overtake them from 2 to 3 order in speed. This is because of architectural differences. Among them are

Arithmetic Unit architecture

specialized units (multipliers, etc.)

regular instruction cycle (RISC-like architecture)

parallel processing

Harvard Bus architecture

Internal memory organization

Multiprocessing organization

local links (TMS320C40)

memory banks interconnection (TMS320C80)
