yksisuoritinjärjestelmä

Yksisuoritinjärjestelmä refers to a computer system that utilizes a single central processing unit (CPU). This is in contrast to multi-processor systems which employ two or more CPUs. In a single-processor architecture, all computational tasks and data processing are handled by this one central unit. This architecture was the standard for personal computers and many other computing devices for a significant period of technological development.

The operation of a yksisuoritinjärjestelmä involves the CPU fetching instructions from memory, decoding them, and then executing them. This sequential execution of instructions forms the basis of how the system performs its functions. While simpler and often less expensive to design and manufacture, single-processor systems can become a bottleneck for demanding applications that require parallel processing capabilities. As software and hardware complexity increased, the limitations of a single CPU became more apparent, leading to the widespread adoption of multi-core processors and multi-processor systems. However, yksisuoritinjärjestelmät remain relevant in certain embedded systems and less computationally intensive applications where cost and power efficiency are primary concerns.
