INTRODUCTIONComputer architecture can be defined as a set of methods or rules that describes theorganization, functionality and implementation of computer systems. In other words it is aspecification detailing of set of hardware or software technology standards that interact to form aplatform or a computer system. In short it refers to the way a computer system is designed andthe technologies it is compatible with (Tlili, Essalmi & Jemni, 2015). It involves instruction setarchitecture design, logic design, microarchitecture design and implementation. There are mainlythree categories of computer architecture which are system design that includes all the hardwarecomponents in the system, instruction set architecture which is the embedded programminglanguage of the central processing unit and lastly microarchitecture which is also known ascomputer organization and defines the path, storage elements and data processing. In thisassignment Evolution of microprocessors will be discussed, complete description ofmultiprocessors and multicores will be discussed and lastly difference between multiprocessorsand multicores will be discussed.MAIN BODYOverviewMicroprocessors are one of the most crucial important central parts of computers or ofany advance computer devices. It also integrates all the function of central processing unit. It ismostly responsible for carrying out all the programmed instructions into a single circuitintegrated, which is an important thinking device of the machines (Pile, 2016). It is designed insuch a way that it incorporates tremendous processing power in a very small space.Evolution of microprocessor in the 70'sIn 70's IBM was the first company to provide pioneering work associated with the firstgeneration microprocessor technology (4 bit chip). Power of those microprocessors was and stillmeasured in bits. It used simple 0 and 1 binary coded instructions, which was interpreted by thecomputer in order to carry out tasks. Those 4 bit chips were extremely simple and gave weight-age to Moore's Law of prophetic prediction which predicted the capacity of integrated circuits ofcomputers. Intel 4004, a four-bit microprocessor was also evolved in 70's to be used incomputing industry. These 4-bit microprocessors were initially used in calculators which usedbinary decimal codes.
