RISC Designs OutPerforms CISC

RISC (Reduced
Instruction Set Computers) were designed analytically to deliver
the most processing power per clock cycle. As a result, these
RISC systems are the favored choice for embedded systems where
low power is an issue. Also, these systems offer more configuration
flexibility; you are not tied to a "PC Paradigm" with a fixed
BIOS, a limited number of serial ports and so forth.
