Q
What does CISC mean
A
Complex Instruction Set Computer
3
Q
What are the properties of RISC
A
- Small instruction set
- Each instruction is one line of machine code
- Used in everyday devices
4
Q
What are the properties of CISC
A
- Large instruction set
- Instructions are built into hardware
- Used in embedded systems and microprocessors
5
Q
What are the benefits of RISC processors
A
Pipelining is possible since each instruction takes one clock cycle.
The CPU can access and process instructions faster.
Fewer transistors needed so lower heat costs
6
Q
What are the benefits of CISC processors
A
Compilers have less work to do
Requires less RAM since instructions are smaller
Programmers can write more efficient programs
