of information they can handle at any time, in the complexity of the

operations they actually do, in the way they are connected to the

external world, in their power-supply requirements, and in their

immunity to mechanical vibration and electrical noise. Other factors

that might affect the selection of a microprocessor for a particular task

are the number of manufacturers (to ensure continuity of supply) and

the provision of software aids. Perhaps the most important single point

is the degree to which the system design engineer is familiar with a

particular type of microprocessor; the sheer labour of learning about a ...
