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.
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 ...
M·CORE processors, like 68000 family processors, have a user mode and a supervisor mode, and in user mode both see a 32 bit PC and 16 registers, each 32 bits. The M·CORE instruction set is very different from the 68k instruction set—in particular, M·CORE is a pure load-store machine and all M·CORE instructions are 16 bit, while 68k ...
The jump from the 68000/68010 to the 68020/68030, however, represents a major overhaul, with innumerable individual changes. By the time the 68060 was in production, Motorola had abandoned development of the 68000 family in favor of the PowerPC. The 68060 is the last 68000 family processor from Motorola.
The NXP ColdFire is a microprocessor that derives from the Motorola 68000 family architecture, manufactured for embedded systems development by NXP Semiconductors. It was formerly manufactured by Freescale Semiconductor (formerly the semiconductor division of Motorola ) which merged with NXP in 2015.
Die of a Motorola 68LC040. The 68LC040 is a low cost version of the Motorola 68040 microprocessor with no FPU. This makes it less expensive and it draws less power. Although the CPU now fits into a feature chart more like the Motorola 68030, it continues to include the 68040's caches and pipeline and is thus significantly faster than the 68030.
The initial model has a 10 MHz Motorola 68000 CPU, 1 MB of RAM, and lacks a hard drive. The final model was released in 1993 with a 25 MHz Motorola 68030 CPU, 4 MB of RAM, and optional 80 MB SCSI hard drive.
