On 32 bit "successful" architectures: IBM System/360 and its 32-bit successors (loosely the base of the intel 32 bit family), the Intel IA-32 32-bit version of the x86 architecture, the DEC VAX, the Motorola 68k, and the 32-bit versions of the ARM, SPARC, MIPS, PowerPC and PA-RISC architectures. 32-bit instruction set architectures used for embedded computing include the 68k and ColdFire, x86, ARM, MIPS, PowerPC, and Infineon TriCore architectures. Seems like more than six.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
