What is odd a machine, believe a lot of people still do not know. Also do not know sheet piece what is the action of machine. Odd abbreviation is a machine odd a small controller (Microcontroler) , it is not the chip of function of logic of the certain that finish, however all of a computer science department compositive go up to a chip, be equivalent to the computer of a miniature, because it is used the earliest in industry,dominate a field. Odd a machine develop by the special processor of only CPU inside chip and come. The earliest design concept is to pass will much peripheral equipment and CPU compositive in a chip, make tube-shaped part of computer science department smaller, easier and compositive into complex and ask to alluding among strict control equipment. The Z80 of Intel is the earliest the processor that goes out according to design of this kind of thought, evermore, odd a machine and the development of special processor part company. The picture comes from a network everybody knows our computer is main is by CPU of unit of the processing central (have operation, control) , random memory RAM (data stores) , memory ROM (the program stores) , input / output equipment I/O (serial mouth, collateral output. Installation is given priority to in what be weighed board presswork on circuit board, the computer that is our individual. sheet piece machine regard as a whole is divided into 4 very easy understanding. these things (CPU, hard disk, memory, advocate board etc) with collect agglomerate after been do, following plan institute inspect: Stand-alone piece became us to want to learn " odd a machine " . And in stand-alone piece in-house, CPU, hard disk, memory, advocate board it is another names however etc. 1) CPU (Central Processing Unit) . It is odd the core component of a machine, include arithmetic unit and controller. ALU of unit of logic of arithmetic of arithmetic unit since (Arithmetic Logic Unit) , its function is to have arithmetic manipulation and logistic operation. Controller is mixed by encoder of instruction register, instruction, sequential circuit commonly control circuit composition. Acting well is to finish take an instruction, form instruction coding all sorts of small operations and implement a directive, land of each part in an orderly way that control the computer at the same time work. Cpu interior pursues 2) the memory in the computer, in sheet piece data calls memory in machine, also call random memory. With RAM (Random Access Memery) express. Its action is the intermediate result that is used at depositing operation, data of short duration puts gentle to rush, mark wait. The characteristic is: The meeting after dropping report loses data. Program memory 3) the hard disk in the computer, in sheet piece in machine, call a program memory, also cry read-only memory. With ROM (Read Only Memery) express. Its action and hard disk are similar, with will deposit user program. The characteristic is: Data won't be lost after dropping report. 4) input / output equipment I/O " advocate board " , in sheet piece in machine, be called I/O (the input exports equipment) also included serial opening of course, collateral mouth, timer, time implement etc. Odd the use field of a machine is very extensive already, if labour of intelligent appearance, real time accuses, communication equipment, navigation system, electric home appliancesCNC Milling
