Three main types of microprocessors
- Approaches to reducing system cost
- Approaches to increasing system speed
- Approaches to reducing electromagnetic emissions
RISC vs. CISC
We have learned the general concepts of computer hardware in last three lectures. In this lecture, we will study how these general concepts are used and extended in modern microprocessors. Microprocessors are designed to meet different requirements, for example, fast speed, versatile functionality, low cost, or combinations thereof. This lecture introduces techniques for satisfying these requirements by using three types of microprocessors: microcontrollers, digital signal processors, and general purpose processors.
