摘要： Filters and methods for managing presence counter saturation are disclosed. The filters can be coupled to a collection of items and maintain information for determining a potential presence of an identified item in the collection of items. The filter includes a filter controller and one or more mapping functions. Each mapping function has a plurality of counters associated with the respective mapping function. When a membership status of an item in the collection of items changes, the filter receives a membership change notification including an identifier identifying the item. Each mapping function processes the identifier to identify a particular counter associated with the respective mapping function. If a particular counter has reached a predetermined value, a request including a reference to the particular counter is sent to the collection of items. The filter receives a response to the request and modifies the particular counter as a result of the response.

摘要： Apparatus and techniques for predicting a storage address based on contents of a first program accessible register (PAR) specified in a first instruction, wherein the first PAR correlates with a target address specified by a second PAR in a second instruction. Information is speculatively fetched at the predicted storage address prior to execution of the second instruction. The first instruction is an advance correlating notification (ADVCN) instruction, the second instruction is an indirect branch instruction, and the information is a plurality of instructions beginning at the predicted storage address. The predicted storage address is a branch target address for the indirect branch instruction from which instructions are speculatively fetched. The prediction is based on contents of the first PAR specified in the ADVCN instruction. The contents of the first PAR correlate with a taken evaluation of the branch instruction.
