Computer Organisation and Architecture-Designing for performance

In computer science and engineering, computer architecture is a set of disciplines that describes a computer system by specifying its parts and their relations.
For example, at a high level, computer architecture may be concerned with how the central processing unit (CPU) acts and how it uses computer memory. Some fashionable (2011) computer architectures include cluster computing and non-uniform memory access.
Computer architects use computers to design new computers. Emulation software can run programs written in a proposed instruction set. While the design is very easy to change at this stage, compiler designers often collaborate with the architects, suggesting improvements in the instruction set.
