The Motorola 68000 (sometimes shortened to Motorola 68k or m68k and usually pronounced "sixty-eight-thousand") [2] [3] is a 16/32-bit complex instruction set computer (CISC) microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector. The design implements a 32-bit instruction set, with 32-bit registers and a 16-bit internal ...
The Motorola 68000 series (also known as 680x0, m68000, m68k, or 68k) is a family of 32-bit complex instruction set computer (CISC) microprocessors.During the 1980s and early 1990s, they were popular in personal computers and workstations and were the primary competitors of Intel's x86 microprocessors.
Woodcrest added support for the SSSE3 instruction set. Merom was the first Mac processor to support the x86-64 instruction set, as well as the first 64-bit processor to appear in a Mac notebook. Clovertown was the first quad-core Mac processor and the first to be found in an 8-core configuration.
A Motorola MEX68KECB Microcomputer, circa 1981. This microcomputer is based on a Motorola 68000 16/32-bit microprocessor. The Motorola 68000 Educational Computer Board (MEX68KECB) was a development board for the Motorola 68000 microprocessor, introduced by Motorola in 1981.
The 68010 was never as popular as the 68000. However, due to the 68010's small speed boost over the 68000 and its support for virtual memory, it can be found in a number of smaller Unix systems, both with the 68451 MMU (for example in the Torch Triple X), and with a custom MMU (such as the Sun-2 Workstation, AT&T UNIX PC/3B1, Convergent Technologies MiniFrame, Plexus P/15 and P/20, [5] NCR ...
The 6800 ("sixty-eight hundred") is an 8-bit microprocessor designed and first manufactured by Motorola in 1974. The MC6800 microprocessor was part of the M6800 Microcomputer System (later dubbed 68xx [1]) that also included serial and parallel interface ICs, RAM, ROM and other support chips.
It also had split instruction and data caches of 4 kilobytes each. It was fully pipelined, with six stages. [3] Versions of the 68040 were created for specific market segments, including the 68LC040, which removed the FPU, and the 68EC040, which removed both the FPU and MMU. Motorola had intended the EC variant for embedded use, but embedded ...
Die of Motorola 68882. The 68882 is an improved version of the 68881, with better pipelining, and eventually available at higher clock speeds. [3] [4] Its instruction set is exactly the same.
