Assume the cache can hold 64 kB. Data are transferred between main memory and the cache in blocks of 4 bytes each. This means that the cache is organized as 16K=2^14 lines of 4 bytes each. The main memory consists of 16 MB, with each byte directly addressable by a 24-bit address (2^24 =16M). Thus, for mapping purposes, we can consider main memory to consist of 4M blocks of 4 bytes each. Please show illustrations too for all work. Part...

7.3 What is the memory layout of the 16-bit value, 0x7654 in a big-endian 16-bit machine, and a little-endian 16-bit machine? b. What would the layouts be in 32-bit machines? 7.19 A certain two-way set-associative cache has an access time of 4 ns, compared to a miss time of 60 ns. Without the cache, main memory access time was 50 ns. Running a set of bench-marks with and without the cache indicated a speedup of 90%. What is the approximate...
