Webcache.20 Disadvantage of Set Associative Cache ° N-way Set Associative Cache versus Direct Mapped Cache: • N comparators vs. 1 • Extra MUX delay for the data • Data comes AFTER Hit/Miss ° In a direct mapped cache, Cache Block is available BEFORE Hit/Miss: • Possible to assume a hit and continue. Recover later if miss. Cache Data Cache ... WebIn k-way set associative mapping, Cache lines are grouped into sets where each set contains k number of lines. A particular block of main memory can map to only one particular set of the cache. However, within that set, the …

Given this binary bit pattern, 0100 , what is the SET?
WebThe cache, called way-predicting set-associative cache, speculatively selects a single way, which is likely to contain the data desired by the processor, from the set designated by a memory address, before it starts a normal cache access. By accessing only the single way predicted, instead of accessing all the ways in a set, energy consumption ...
