Although we hope to do as much programming as possible in high-level languages, the instruction set is the key to analyzing the performance of programs. By understanding the types of instructions that the CPU provides, we gain insight into alternative ways to implement a particular function.
We use four CPUs as examples. The ARM processor [Fur96, Jag95, Slo04] is widely used in cell phones and many other systems. (The ARM architecture comes in several versions; we will concentrate on ARM version 7.) The PIC16F is an 8-bit microprocessor designed for very efficient, low-cost implementations. The Texas ...
