A tag look-up unit implements two thresholds, which may be configurable thresholds, to manage the number of cache lines related to a given set that store dirty data or are reserved for in-flight read requests. If the number of affirmatively associated cache lines in a given set is equal to a maximum threshold, the tag look-up unit stalls future requests that require an available cache line within that set to be affirmatively associated. To reduce the number of stalled requests, the tag look-up unit transmits a high priority clean notification to a frame buffer logic when the number of affirmatively associated cache lines in a given set approaches the maximum threshold. The frame buffer logic then processes requests associated with that set preemptively."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cache and associated method with frame buffer managed dirty data pull and high-priority clean mechanism","description":"Systems and methods are disclosed for managing the number of affirmatively associated cache lines related to the different sets of a data cache unit.
