Q is an integer at least (N+J+X−1). In a first mode: set selection logic selects one set using the index and LSB of the tag; comparison logic compares all but LSB of the tag with all but LSB of each tag in the selected set and indicates a hit if a match; otherwise allocation logic allocates into the selected set. In a second mode: the set selection logic selects two sets using the index; the comparison logic compares the tag with each tag in the selected two sets and indicates a hit if a match; and otherwise allocates into one set of the two selected sets."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-mode set associative cache memory dynamically configurable to selectively select one or a plurality of its sets depending upon the mode","description":"A cache memory stores 2^J-byte cache lines and includes an array of 2^N sets each holding tags each X bits, an input receives a Q-bit memory address, MA[(Q−1):0], having: a tag MA[(Q−1):(Q−X)] and an ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9798668","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
