- the RISC vs CISC controversy
- CISC
- frequently used code as (complex) instructions
- increase lower level programming productivity
- extensive market penetration
- RISC
- very few of the complex instructions are used (empirical studies)
- therefore a reduced instruction set is more efficient
- programs are 20% larger , requiring more disk space and memory
- much more registers are needed, but speed of programs written for RISC is close to twice of equivalent for CISC.
- facilitate scalability
