Difference's Between Reduced instruction Set computer(RISC) and Complex Instruction Set Computer(CISC) are follows
RISC
|
CISC
|
RISC stands for Reduced Instruction Set Computer.
|
CISC - for Complex Instruction Set Computer.
|
Fewer register.
|
Many register.
|
Less complex
microcode.
|
Complex microcode.
|
RISC systems
shorten execution time, by reducing the clock
cycles per
instruction (i.e. simple instructions take less time
to interpret). |
CISC systems
shorten execution time, by reducing the
number of
instructions per program.
|
Mainly used for real time applications.
|
Mainly used in normal PC’s, Workstations and servers .
|
Examples
of RISC Processors: Atmel AVR, PIC, ARM.
|
Examples of CISC
Processors: Intel x86.
|

|
Instruction pipe lining can not be implemented easily.
