Can you give me three examples of RISCreduce instruction set computer?

good example for RISC processors is DSP (Digital signal processing) processors.

simillarly for cisc processors is microprocessor.we can understand the difference between these two by a simple example.

here it is, Convolution in terms of DSP is nothing but continuous multiplication.

cisc processor performs multiplication by continious addition.but risc processor perform continious multiplication in a single pipeline architecture.
