WebSet Associative Mapping Algorithm POINTS OF INTEREST: • Address length is s + w bits • Cache is divided into a number of sets, v = 2d Tag • k blocks/lines can be contained within each set • k lines in a cache is called a k-way set associative mapping • Number of lines in a cache = v•k = k•2d • Size of tag = (s-d) bits The K-way set associative mapping is like a mix of fully associative and direct mapping. Here, 1. The total number of sets = The total number of lines/K 2. K refers to the K-way set associative 3. K= 23 for a 2-way set associative 4. The total number of sets = 4/2 or 2 sets (S1, S0) The blocks mentioned above would … See more In case a cache has 4 lines, and we consider a 2-way set associative, then: Here, we search for a certain block through the tag (leading to Cache Hit or Cache miss). Now, … See more The formula for K-way is as follows: 1. Physical address = set + tag + block offset 2. The comparator value in the case of a k-way set associative would be = (k-value) – (tag bit). For example, (7-8) would mean that the 7 lines of a … See more Pros: The comparison time is reduced in the K-way set associative mapping as compared to the fully associative mapping. Cons: It involves the factor of conflict miss. For example, The person who lives in a single … See more
Direct Mapping in Cache Memory - DigitalThinkerHelp
WebSep 29, 2024 · In a k-way set associative cache, the cache is divided into v sets, each of which consists of k lines. The lines of a set are placed in sequence one after another. The lines in set s are sequenced before the lines in set (s+1). The main memory blocks are numbered 0 onwards. WebIn fully associative mapping, A block of main memory can be mapped to any freely available cache line. This makes fully associative mapping more flexible than direct mapping. A replacement algorithm is needed to replace a block if the cache is full. In this article, we will discuss practice problems based on fully associative mapping. gregg morrison preston school
