Editing NXP ColdFire (section)

==Instruction set==
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 [[Motorola 68000|68000]]. When compared to classic 68k hardware, the instruction set differs mainly in that it no longer has support for the [[binary-coded decimal]] (BCD) packed data format; it removes a number of other, less used instructions; and most instructions that are kept support fewer [[addressing mode]]s. Also, [[floating point]] intermediates are 64 bits and not 80 bits as in the [[Motorola 68881|68881 and 68882]] [[coprocessor]]s. The instructions are only 16, 32, or 48 bits long, a simplification compared to the [[Motorola 68000 family|68000 series]].
