Basic CPU Architecture

Basic CPU Architecture
All processors since the humble 8086 operate along similar principles using a basic fetch-decode-execute procedure. Before going on to look at real-world processors like the Pentium and the Athlon and their associated complexities, we will look at BORIS - Beginners Optimised Reduced Instruction Set processor.
Beginners Optimised Reduced Instruction Set (BORIS)
The basic architecture of BORIS is shown in Figure 1.
The BORIS processor contains all the basic components required for a CPU including:
