Microprocessor characteristics & Architecture Classifications A microprocessor is a processor whose all components have been sufficiently miniaturized to be grouped in a single box. Functionally, the processor is the part of a computer that executes instructions and processes program data. The integrated circuit (IC) , also called electronic chip, is an electronic component, based on a semiconductor, reproducing one or more electronic function (s) more or less complex (s), often integrating several types basic electronic components in a small volume (on a small plate), making the circuit easy to implement. There is a very wide variety of these components divided into two broad categories: analog and digital. A computer program is a set of operations intended to be executed by a computer. A source program is a code written by a computer scientist in a programming language. It can be compiled into a binary ...
