Intel Processor History

Here are a few historical development of the processor and the Intel clone of its successful disarikan

* Debut Intel processor series starting with MCS4 which is the embryo of the processor's i4040. 4-bit processor is planned to be a brain calculator, in the same year (1971), Intel i440 to make revisions. Originally ordered by a Japanese company for the calculator, the processor is much more powerful than expected so that Intel's purchase rights to Japanese companies for the development and further research. Here for the development of the embryo of the processor to the computer.

* Next show 8-bit processor in the first i8008 (1972), but somewhat less preferred because multivoltage .. ago showing the new processor i8080, here there is a change in voltage that is a triple, a technology NMOS (PMOS no more), and introduce the first time the system clock generator (up additional chip), packed in the form of Array DIP 40 pins. Then also appear processor2: -1974 Motorola's MC6800, Z80 from Zilog -1976 (are the two rival weight), and another series prosessor2 artificial MOST 6500, Rockwell, Hyundai, WDC, NCR ff. Z80 full compatible with the i8008 only until the machine language level. Level rakitannya different language (not compatible level software). I8080 processor is the processor's internal registers with the 8-bit external bus 8-bit memory addressing and 20-bit (can access 1 MB total memory), and operating mode REAL.

* 77 Thn 8085 show, generatornya onprocessor clock, cikal bakalnya the use of single voltage +5 V (the implementation of s / d 486DX2, DX4 starting at +3.3 V ff).

* I8086, with the processor registers, 16-bit external data bus, 16-bit memory addressing and 20-bit. 78 yr Direlease using HMOS technology, components support 16 bit bus are very rare, so the price becomes very expensive.

* And for the market demand appear i8088 16bit internal bus, external bus 8bit. So that components can use i8088 peripherals 8bit former i8008. IBM chip select for this pebuatan IBM PC because it is cheaper than the i8086. If only the CEO of IBM PC that does not express mere side only dream, of course, IBM will take the total PC market at this time. IBM PC first release in August 1981 has 3 versions of IBM PC, IBM PC-Jr and IBM PC-XT (extended technology). I8088 chip is very popular, until the NEC has launched a chip that is built on the pin chip specification, which is named V20 and V30. NEC V20 and V30 is compatible with the processor to Intel assembly level language (software).
