A Motorola 680x0/0x0/m68k/68k/68K family of CISC microprocessor CPU chips were 32-bit from a begin, & were the primary competition for the Intel x86 family of chips. A 68k personal rest on Motorola's 8/16-bit 68h series of processors.
The 68k family members
Architectural heritage
Humans world health organization come acquainted a PDP-11 or VAX usually feel comfortable sustaining a 68000. Sustaining the exception of a split of general purpose registers into specialised information & location registers, the 68000 architecture is around several ways a 32-bit PDP-11.
Where did the 68050 go? Was there no -070?
Note that no 68050, this is because a project that was destined to exist as the 68050 was in time freed as a version of the 68040. There exists likewise there is no revision of the 68060, as Motorola was in a run of shifting out of the 68k & 88k processor lines into its new PowerPC business, so a 68070 was never developed. Experienced it been, it would keep around been the revised 68060.
The next 68k generation
A Quaternary generation 68060 shared most of the features of the Intel P5 architecture of x86. Should Motorola own decided to stick by owning a 680x0 series these are very likely that a next processor (68080) would have resembled Intel's P6 architecture.
Other variants
When a mainline 68k processors' death, a 68k personal has been utilized to occasionally extent within microcontroller/embedded microprocessor versions. These chips include a ones enrolled under "other" above, i personally.e. a CPU32 (aka 68330), the Coldfire, and a Dragonball.
Competitors to the mainstream 68ks
A chief contender in the microcomputer market for generation one were a x86 architecture P1 and P2 IA-16 chips (8088, 80286). For generation 2, it was a P3 IA-32 chips (80386), and for generation ternary it was a P4 IA-32 chips (80486). Generation quaternion did compete against a P5 IA-32 chips (Pentiums), but less, as much of the yet 68k marketplace was shifting assibilate to the PowerPC, sounding the demise knell for the 680x0 on the desktop.
