摘要： An arbiter in a communication system including a plurality of request shapers in communication with a plurality of requestors. Each request shaper is configured to receive a request for access to a resource of the communication system, initially assign a priority level to the request upon receipt of the request, increase an age of the request, after increasing the age of the request, compare the age of the request to a delta period value associated with the respective requestor, and repeatedly increase the priority level of the request based on the comparison. Each of the plurality of requestors has a corresponding delta period value that is different from that of other ones of the plurality of requestors. An arbiter core is configured to grant one of the plurality of requestors access to the resource based on the priority level of each request and the age of each request.

摘要： An arbitration circuit for granting access to a shared resource among requestors comprises N request shapers, where N is an integer greater than one. An input unit receives a request from a requestor. An age unit assigns an age to the request and increases the age of the request when the requestor is not granted access to the shared resource. A priority unit assigns a priority level to each of the requests and selectively increases the priority level of the request based on the age of the respective one of the requests and a delta period of the request. An arbiter core receives the requests from the N request shapers and selectively grants access to the shared resource to each of the requestors corresponding to the requests based on the priority level and age of the requests. The delta period of one of the N request shapers is different than the delta period of another of the N request shapers.

摘要： Power consumption is managed in a subscriber station of a communication system. The subscriber station is engaged in a sleep mode, including reducing a frequency of a system clock of the subscriber station. When the subscriber station receives, while in the sleep mode, a message having downlink transmission parameters while, the frequency of the system clock of the subscriber station is increased to process the message. After processing the message, the frequency of the system clock is reduced.

摘要： A communication system including a resource and an arbiter. The resource is shared among a plurality of requestors such that, at any given time, only one of the plurality of requestors has access to the resource. The arbiter is configured to receive a request from each of the plurality of requestors to access the resource, in which each request has a priority level associated with the request. The arbiter is further configured to age each request at a different rate relative to that associated with another request, and grant each requestor access to the resource based on i) the priority level and/or ii) the age of the request corresponding to the requestor.

摘要： Various approaches grant access to a shared resource. An arbitration circuit includes request shapers that each receive a request from one of the requestors and assign a respective predetermined priority level and age to each of the requests. An arbiter core receives the requests and grants access to the shared resource to each of the requestors corresponding to the requests. The arbiter core includes a mask circuit that includes a plurality of mask registers each corresponding to a respective one of the priority levels. The age of a respective one of the requests increases when the corresponding one of the requestors is not granted access to the shared resource. The priority level of a respective one of the requests increases according to the age of the respective one of the requests.
