"The Coldfire instruction set is "assembly source" compatible (by means of translation software available from the vendor) and not entirely object code compatible with the 68000."

This is very vague. Can someone tell the differences in instruction set? And what does "not entirely" mean?


 * Coldfire is basically a subset of the 68000, plus a couple features borrowed from the 68020. The coding of the instructions seems to be the same (at least the ones I checked), meaning you should be able to run Coldfire programs on a 68020. Mirror Vax 14:17, 26 November 2005 (UTC)

According to the 68080 article, the fastest 68060s were running at 75MHz, which contradicts this article. Anybody in the know who wants to fix this. ---84.150.98.18 15:00, 12 January 2007 (UTC)

The sentence "Newer models of ColdFire are compatible enough with 68k processors that it is now possible to create binary compatible Amiga clones." makes no sense. Such Amiga clones have (in theory) the same possibilities (or likeliness) as 68k Mac clones or whatever 68k Hardware clone you like. As long as no such clone exists (and there's no sign for anything else than vapourware) there is no reason to mention such thing in an encyclopedia. 212.144.6.150

I don't think the V5 core is delivered. —Preceding unsigned comment added by 203.47.38.170 (talk) 22:28, 17 January 2008 (UTC)

Coldfire V5 core is (so far) vaporware and doesn't belong in an encyclopedia article as it refers to speculative future events — Preceding unsigned comment added by 62.202.116.51 (talk) 12:05, 5 May 2012 (UTC)

68060@75MHz
The fastest full 68060 was 66MHz. The 75MHz version was LC, think the MMU and/or FPU didn't work reliably at such high clocks. 68060s have been overclocked to 100MHz and more. The chip produced less heat than a Pentium and was often run fanless and even heatsinkless. Not sure what this means for speed comparisons, though. There was no 60MHz 68060, though. So I have editted the page. Might try to dig up a link/reference for the datasheet or something 122.107.110.187 (talk) 00:22, 6 April 2008 (UTC)

disambiguation page?
There are already two options (the CPU line and trilogy), but "Coldfire" is also an old name for (wet) gangrene. In historic contexts, this is the more common meaning — Preceding unsigned comment added by 88.159.64.210 (talk) 15:22, 29 October 2011 (UTC)

Is it RISC?
Is NXP Coldfire a RISC cpu? The changes they made from the 68000 family, removing unaligned memory access and seldom used, complex instructions, are typical of RISC chips. NXP states "All ColdFire cores feature a variable-length RISC architecture for           compact code ..." https://www.nxp.com/products/nxp-product-information/ip-block-licensing/coldfire-32-bit-processors:COLDFIRE-32-BIT-PROCESSORS.
