First making its name compilers and programming tools for the Motorola 680x0
chip, Metrowerks went on to dominate the Apple Macintosh programming market from the launch of the first PowerPC-based machines.
Two principal lines of microprocessors are evaluated--the 80x86 line, including clones, and the 680x0 line, including follow-on Powerpc microprocessors.
Data for both register and bus width are available for 80x86 and 680x0 microprocessors.
The first caches on 680x0 microprocessors held only instructions, but more recent types of 680x0 microprocessors have separate caches for instructions and for data.
It is true that graphics productivity will run much faster on Macintosh systems that use PowerPC processors than they do now on personal computers that use Motorola 680x0 or Intel 486 chips.
The two types of equipment will coexist for some time, and upgrades will be offered for many 680x0 models.
Other microprocessors supported by the lab include the Motorola 680x0
series, the Texas Instruments TMS320Cx5 DSP series, and the Intel 8096 series.
Amoeba started out on the 680x0
CPUs, and has been easily moved to the VAX, and Intel 80386.
An ABI is written separately for each processor arthitecture (like the Intel 80386 or Motorola 680X0
, for example) and allows software developers to create applications that run on all computers based on the same microprocessor.
Cheap CDs of release 2.1 for Alpha, SPARC, Motorola 680x0
and Intel x86 systems will be available from Debian distributors soon.
A CD-I player contains an optical disc drive, a Motorola 680X0
CPU, and a megabyte of memory, but it will be marketed as an enhanced CD player, not a computer.
The Butterfly Multiprocessor consists of up to 256 nodes, each of which has a Motorola 680x0
processor, special switching hardware, and up to 4 Mbytes of memory.
