Bus arbitration |
摘要 |
Access to a bus in a computer system having a CPU and bus devices capable of running cycles on a bus is controlled by an arbiter. The arbiter grants access to the bus according to an arbitration scheme that depends on whether a request for the bus is pending from the CPU, in which a first arbitration scheme arbitrates between the bus devices, and wherein a second arbitration scheme arbitrates between the CPU and at least one other bus device if the CPU request is present.
