uniprocessor

[′yü·nə‚prä‚ses·ər]

(computer science)

A computer that has a single central processing unit and works sequentially on only one program at a time.

uniprocessor

(processor)

(From "uni" - one) A computer with a single central processing unit, in contrast to a parallel processor. Most personal computers are currently (March 1997) uniprocessors. Some more expensive computers, typically servers, have multiple processors to provide increased throughput.

uniprocessor

A single processor. As more and more computers employ multiprocessing architectures, such as SMP and MPP, the term is used to refer to a system that still has only one CPU. Although most desktop computers are uniprocessor systems, it is expected that dual processor systems will become commonplace on the desktop in the coming years.

We have resisted the temptation to provide a more detailed model of the individual processors taking into account factors such as cache size or pipeline structure, and rely instead on the existing body of knowledge in implementing fast sequential algorithms on modern uniprocessor systems to fill the gap.

A practical model of parallel computation

Parallel-processing systems are especially appropriate for storing and managing huge amounts of data because no uniprocessor system and no disk drive are fast enough to search for and transmit the data on demand, said Convex's Masson.
