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: &…

…Tab/>Symmetric Multi-processing in which each CPU has equal access to resources and control of the operating system. Symmetric multiprocessing provides better use of resources and is more reliable and fault tolerant, but it is difficult to implement. Windows NT/200 are examples of operating systems that can do symmetric Multi-processing. Asymmetric Multi-processing has the advantage of simplicity but is more unreliable as failure of the master CPU means failure of the entire system.
