The Motorola 68000 is a CISC microprocessor, the first member of a successful family of microprocessors, which were all mostly software compatible.
Motorola ceased production of the 68000 in 2000, although derivatives, notably the CPU32 family, continue in production.
The Motorola 68901 had a number of severe defects, including the ability to lose the highest-priority interrupt if it and the clock interrupt happened within some window of each other.

In re lation to its predecessor, the ColdFire ISA produces object images that are considerably smaller than 68000 object images, but not as compact as objects targeted for the 68040.
Register-to-register instructions are executed in a single pipeline cycle with the operands fetched during the OC (Operand Fetch Cycle) phase of the OEP pipeline, and the actual execution is performed in the EX (execute) phase of the OEP pipeline.
The ColdFire ISA is not a pure load/store architecture, so there are numerous compound instructions that combine a load operation with some type of arithmetic or logical operation.

The Freescale ColdFire is a 68k architecture microprocessor manufactured for embedded systems development by Freescale Semiconductor (formerly the semiconductor sector of Motorola).
When compared to classic 68k hardware, the instruction set differs mainly in that it no longer has support for the Binary Coded Decimal, or BCD packed data format; it removes a number of other, less used instructions; and most instructions that are kept support fewer addressing modes.
They can be clocked as high as 300MHz, as compared to the 60MHz of a 68060 (the fastest "real" m68k processor) without overclocking.

From: Jaap van Ganswijk <ganswijk@xs4all.nl> To: chipdir-L, 6805, 6811 Subject: About the Coldfire Hi, Grant Beattie and I had a little discussion about what the Coldfire was: 68000 or PowerPC and if it is a processor or a controller.
When you look on page: www.mot.com/SPS/HPESD/prod/coldfire/ the hype is that the 'ColdFire represents a revolutionary variable-length RISC architecture that is designed to meet the requirements of the embedded consumer market.' But also: 'ColdFire's creation sprung from the 68K architecture.' The source code at: www.mot.com/SPS/HPESD/aesop/cf/gen/fft_s.txt clearly shows that it uses 68000 source code indeed.
I couldn't find any of the Coldfire devices in the price guide at: www.mot-sps.com/cgi-bin/pg but finding something at the Motorola WWW site(s!) has never been easy and must probably be seen as an 'interesting' challenge for the overworked engineer...

Trust me, it was frustrating when I was first bringing up the OS on the 1200 and had to rely on an external Logic Analyzer and a fairly expensive "clip" just to see the code flow.
It's best to think of the Coldfire in the 1200 as a 68040, that's really the way it works for almost all purposes (code wise).
The Coldfire does not have an MMU (it uses an ACU instead), so it's not possible to run Linux without doing some significant work.
