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.
A Motorola 68020 processor. The Motorola 68020 was the first 32-bit Mac processor, first used on the Macintosh II.The 68020 has many improvements over the 68000, including an instruction cache, and was the first Mac processor to support a paged memory management unit, the Motorola 68851.
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.
A Motorola 68EC060 microprocessor. The Motorola 68060 ("sixty-eight-oh-sixty") is a 32-bit microprocessor from Motorola released in April 1994. [4] It is the successor to the Motorola 68040 and is the highest performing member of the 68000 series. Two derivatives were produced, the 68LC060 and the 68EC060.
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 Motorola 68030 ("sixty-eight-oh-thirty") is a 32-bit microprocessor in the Motorola 68000 family. It was released in 1987. The 68030 was the successor to the Motorola 68020, and was followed by the Motorola 68040. In keeping with general Motorola naming, this CPU is often referred to as the 030 (pronounced oh-three-oh or oh-thirty).
A Motorola 68040 microprocessor Motorola 68040 die shot with FPU on the left. The Motorola 68040 ("sixty-eight-oh-forty") is a 32-bit microprocessor in the Motorola 68000 series, released in 1990. [2] It is the successor to the 68030 and is followed by the 68060, skipping the 68050.
