Digital Signal Processors (DSPs)
➡Powerful special-purpose 8/16/32 bit microprocessors
➡Designed specifically to meet the computational demands and
power constraints of today's embedded audio, video, and
communications applications.
➡Digital Signal Processors are 2 to 3 times faster than the general-purpose microprocessors in signal processing applications.
➡DSPs implement algorithms in hardware which speeds up the
execution whereas general-purpose processors implement the algorithm in firmware and the speed of execution depends
primarily on the clock for the processors.
➡DSP can be viewed as a microchip designed for performing high-speed computational operations for ‘addition’, ‘subtraction’,
‘multiplication’ and ‘division’
➡A typical Digital Signal Processor incorporates the following key units:
✅Program Memory
✅Data Memory
✅Computational Engine
✅I/O Unit
➡Audio-video signal processing, telecommunication and multimedia applications are typical examples where DSP is
employed.
