Väyläkontrollerit
Väyläkontrollerit, often translated as bus controllers or bus arbiters, are essential components in computer architecture. They manage the flow of data and instructions between different devices connected to a shared bus. In a system with multiple devices, such as a CPU, memory, and peripheral devices, a bus acts as a common pathway for communication. However, only one device can transmit data on the bus at any given time to avoid collisions and ensure data integrity.
The primary function of a väyläkontrolleri is to determine which device gets access to the bus and
Beyond arbitration, väyläkontrollerit may also handle other bus-related tasks. These can include managing bus cycles (read,
