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.

Aug 6, 2020 · The entire series was often referred to as the m68k, or simply 68k. The Motorola 68000 processor was a 32-bit processor internally, with a 16-bit bus, and is generally considered a more advanced processor than the 8086/8088.

Aug 5, 2008 · The 8086 and the 68000 also differ in how they find the operands for their machine language opcodes, although their addressing modes look less similar at first glance than they actually are. The 8086, as mentioned before, has a 16-bit program counter and four 16-bit “segment registers.”

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.

Oct 6, 2023 · ColdFire can be made entirely 68k compatible with simple low-overhead emulation software. It could be have been a viable path forward for 68k, but they rolled it out almost 10 years too late, after they'd totally given up on 68k. Motorola abandoned 68k, is what happened.

The Z8000 and the 8086 used a segmented memory approach, whereas the 68000 was a flat address space, and focused on addressing as much memory as was realistic without segmentation boundaries (or any of the protection or paging features segmentation might offer!)

The Motorola 68000 (commonly abbreviated as 68k) is a landmark microprocessor introduced in 1979 by Motorola Semiconductor.

Apr 19, 2022 · Although there were definitely other CPUs in use in the 1980s, the vast majority of microcomputers people had at home or at the office used either a MOS 6502 or one of its variants, a Zilog Z80, an early member of the Intel 8086 family, or a Motorola 68000. Let's have a look at those four CPUs. What does a CPU do, anyway?

Sep 25, 2023 · In the era when the 68k and x86 were very popular, the shift to 32 bit CPUs was a race to mass production. No question the 68020 was a cleaner design and almost destined to be the no. 1 choice for new machines.

The 68000 family, or 68K, was one of the first so-called 16-bit microprocessors and a contemporary of Intel's 8086. Unlike the Intel processor, the 68K did not attempt to be backward compatible with a company’s earlier 8- bit chip.
