DSP Vs RISC processor

HI All ,
What is the difference between RISC & DSP Processor .?

Re: DSP Vs RISC processor

Both are two forms of CPU architectures.

DSP are special purpose microprocessors for signal processing i.e. they have extract instructions, addressing modes etc.

RISC are microprocessors for usually generic usage. There are a lot of famous microprocessor families that fall under this e.g. ARM, MIPS etc.

For a detailed comparison of the two you can look at
https://en.wikipedia.org/wiki/Digital_signal_processor
and
https://en.wikipedia.org/wiki/ARM_architecture

DSP has been so widely used a concept that general purpose processors are also incorporating features to support digital signal processing more efficiently.

Re: DSP Vs RISC processor

DSP are special purpose microprocessors for signal processing

Clock speed: 100-200 MHz
• 16-bit (fixed point) or 32-bit (floating point)
buses and word sizes
• 16-24 bit address space
• Some on-chip memory
• Single-cycle execution of most instructions

• 12-16 instructions
• Single-cycle execute
RISC are microprocessors for usually generic usage
