Extracted text: 1. Suppose physical addresses are 30 bits wide. Suppose there is a cache containing 256K words of data (not including tag bits), and each cache block contains 4 words. For each of the following cache configurations below, specify how the 30-bit address would be partitioned. a. direct mapped b. 2-way set associative c. 4-way set associative d. fully associative For example, for a direct mapped cache, you would need to specify which bits are used to select the cache entry and which bits are used to compare against the tag stored in the cache entry.
