A. In the following questions please choose the proper number of underlined options in order to best complete the statement. [4] 1. Cache size is (choose one) smaller/bigger / about the same size as main memory 2. Caches are (choose one) faster/ slower than main memory 3. Accessing multiple elements of an array could be sped up by a cache optimized for choose one) spatial/temporal locality Accessing the same block of memory repeatedly, for example in a function call, could be sped up by a cache optimized for (choose one) spatial/ temporal locality. 4. 5. An infinitely large cache would have (choose one) 0/1/ multiple misses per cache tag. 6. A 32-bit address on a fully associative cache could be made of a (choose one) 26 /28/ 30 bit tag and a (choose one) 3/4/5 bit offset. A store to memory would cause a read from memory in a(n) (choose one) allocate-on-write / no-allocate-on-write cache. 7
