Now George P. Burdell is studying the effect of set-associativity on the cache performance.
Since he now knows the access time of each configuration, he wants to know the miss-rate of
each one. For the miss-rate analysis, George is considering two small caches: a direct-mapped
cache with 8 lines with 16 bytes/line, and a 4-way set-associative cache of the same size. For the
set-associative cache, George tries out a least recently used (LRU) policy.
George tests the cache by accessing the following sequence of hexadecimal byte addresses,
starting with empty caches. For simplicity, assume that the addresses are only 12 bits. Complete
the following tables for the direct-mapped cache and the LRU 4-way set-associative cache
showing the progression of cache contents as accesses occur (in the tables, 'inv' = invalid, and
the column of a particular cache line contains the {tag,index} contents of that line). You only
need to fill in elements in the table when a value changes.
