MC <It moves, compensation>

Full spelling: Motion Compensation
Alias:
Motion compensation
Field:
Multimedia > animated picture > MC

Detecting, the occasion where the image data is compressed, the frame which is continued (the picture) the element which has appeared in between how moved, the technique which it compresses efficiently. It is adopted with MPEG and the like.

With the image compression system which adopts movement compensation, the vector data is used each element in the picture (with present technology which it is moving to some direction in general 16x16 pixel as 1 elements it processes) concerning, by comparison with the picture of the frame front and back.

This vector data is detected the occasion where it compresses, the vector data and remaining finite difference are included to the data which is transferred. The case where it extends it synthesizes the vector data and the finite difference data, it means to reproduce the original picture.

MC68000 <68000>

Field:
Microprocessor > CISC > MC68000

16 bit microprocessor of Motorola corporation (MPU). You call to proper form MC68000. It was announced in 1979, it was adopted for Macintosh of the Apple corporation and X68000 of sharp as CPU of the personal computer. 16 bits MPU, movement to 32 bits was considered, the internal register 32 bit length ago. Because the address bus is 24 bits, it was possible to access the physical memory of 16MB directly, between the programmers it was MPU whose appraisal is high. There is MC68010, MC68020, MC68030, MC68040 and MC68060 etc in the succession processor.

MC68010 <68010>

Field:
Microprocessor > CISC > MC68010

16 bit microprocessor of Motorola corporation (MPU). Those which add virtual memory performance to MC68000 of 1 generations ago.

MC68020 <68020>

Field:
Microprocessor > CISC > MC68020

32 bit microprocessor of Motorola corporation (MPU). It was adopted for Macintosh of the Apple corporation as CPU of the personal computer. Those which MC68010 of 1 generations ago to 32 bits are converted are MC68020.

MC68030 <68030>

Field:
Microprocessor > CISC > MC68030

32 bit microprocessor of Motorola corporation (MPU). As CPU of the personal computer, it was adopted for Macintosh of the Apple corporation and X68030 of sharp. Data cash and memory management unit (MMU) additional ones are MC68030 in MC68020 of 1 generations ago.
