Abstract
An arbiter configured to selectively grant access to a shared bus to a plurality of requestors. The arbiter includes a plurality of request shapers each configured to receive a request signal corresponding to a request, from a respective one of the plurality of requestors, to access the shared bus, a base priority signal indicating a base priority level of the respective one of the plurality of requestors, and a delta period signal indicating a counter value threshold. The counter value threshold corresponds to a threshold amount of time, and the counter value threshold is different for each of the plurality of requestors. Each of the plurality of request shapes is configured to separately output the request signal and a priority signal indicating a priority level of the request based on the base priority level, the counter value threshold, and a counter value.
