uniprocessor
Noun
Meaning
uniprocessor (plural uniprocessors)
(computing) A single processor (CPU) that can work sequentially on a single task at a time.
Examples
A four processor system was maintained by the RSX-11 operating system development team for testing and a uniprocessor system served PDP-11 engineering for general purpose timesharing.
Athlon and Core 2 Duo multiprocessors are socket-compatible with uniprocessor variants, so an expensive dual socket motherboard is no longer needed to implement an entry-level SMP machine.
For games this is usually because writing a program to increase performance on SMP systems can produce a performance loss on uniprocessor systems.
At first, more than one program ran on a single processor, as a result of underlying uniprocessor computer architecture, and they shared scarce and limited hardware resources; consequently, the concurrency was of a serial nature.
Busy-waiting is effective for both uniprocessor and multiprocessor systems.
Hardware solutions On uniprocessor systems, the simplest solution to achieve mutual exclusion is to disable interrupts during a process's critical section.
