Encyclopedia > Motorola Coldfire

The Motorola Coldfire is a 68k architecture microprocessor manufactured for embedded systems development by Motorola (now Freescale Semiconductor). The Motorola 680x0/0x0/m68k/68k/68K family of CISC microprocessor CPU chips were 32-bit from the start, and were the primary competition for the Intel x86 family of chips. ... Microprocessors, including an Intel 80486DX2 and an Intel 80386 A microprocessor (abbreviated as µP or uP) is a computer electronic component made from miniaturized transistors and other circuit elements on a single semiconductor integrated circuit (IC) (aka microchip or just chip). ... An embedded system is a special-purpose computer system, which is completely encapsulated by the device it controls. ... Motorola NYSE: MOT (TYO: 6686) is a global communications company based in Schaumburg, Illinois, a Chicago suburb. ... American corporation Freescale Semiconductor, Inc. ...


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. Presumably this results in a simpler and lower cost instruction decoder. Also, floating point intermediates are 64 bits and not 80 bits as in the 68881 and 68882. The Motorola 68000 is a CISC microprocessor, the first member of a successful family of microprocessors from Motorola, which were all mostly software compatible. ... The Motorola 68881 was a floating-point coprocessor chip that was utilized in some computer systems that used the 68020 or 68030 CPU. The addition of the 68881 chip added substantial cost to the computer, but added a floating point unit that could rapidly perform floating point math calculations. ... The Motorola 68881 was a floating-point coprocessor chip that was utilized in some computer systems that used the 68020 or 68030 CPU. The addition of the 68881 chip added substantial cost to the computer, but added a floating point unit that could rapidly perform floating point math calculations. ...
