The birth of 68000

The destiny of a processor, want to rely on ego to struggle of course, but the course that also should consider the history. 6502 it is such, 68000 also be such.

6052 with cheap with high-powered get victory, just meet again the revolution of personal computer, still encountered Ren Tiantang FC; and 68000 with same price, similar chip volume, acceptance transistor amount is Intel double of 8086, still just the MD that Feng Shijia develops to meet FC head-on.

1977 new year's day, be in 6800 after sufferring a defeat with 6502 competition, motolora company allowed to start a name to be “MACSS”(Motorola Advanced Computer System On Silicon, motolora silicon brilliant is advanced all of computer science department) project plan, begin to develop next generation 16 CPU, tom Gunter is appointed to be the controller of this project.

6502 it is the CPU that Mos science and technology develops according to 6800 frameworks, with low price, superior performance and higher good people are tasted lead rapid and occupational market, hit so that Motolora suffering can'ts bear character.

6502 what divide 8 at that time, company of American country semiconductor had taken the lead in rolling out 16 CPU, to throw rival, do not let the tragedy of 6502 repeat, the group of Gunter decides 16 to bypass, roll out 16/32 directly mix model CPU.

This decision lets Motolora 68000 just roll out till 1979, appeared on the market second year. The 8086 CPU that compares an Intel company appears on the market time fully late two years many.

Do not pass a ground of semiconductor group rub Er is mensurable, the amount biennially of the transistor that can accommodate on integrated circuit can break up one time, function also will promote one times, and the price is changeless, the function of 86000 is compared 8086 have an advantage more. (By the way one, rub Er law is when Maerdi gives the Gordon · that holds the post of Intel company CEO)

68000 use 3.5 micron craft to make, have 32 in-house register, but can upload according to bus line in 16 digit only send data. Speed has 4, 6, 8, 10MHz a variety of, memory of physics of highest support 16MB.

The application of 68000

As go up century the processor with 80 time most advanced initial stage, 68000 in be being applied at workstation of a lot of high end above all, arrived 80 time metaphase, be used in personal computer and printer again inside buy controller chip. As technical progress, 68000 be washed out gradually in computer market, but still active mix at consumption embedded domain.

And in game industry, substrate of opportunity of a few markets took the lead in using 68000 CPU, it is elegant Dali company above all, it is a world next the System 14 of fine company, 16, 18, 24, the NEO GEO of the CPS1/CPS2 of company of X Board, Y Board;Capcom and SNK company.
