For a 7-stage Pipeline where each stage takes 5 ns How long will it take to complete a program with 1500 tasks (instructions)? How long would it take to complete the program without a Pipeline? What is the actual Speed-Up offered by completing the program using the Pipeline? What is the theoretical Speed-up offered by completing the program using the Pipeline? Suppose a computer using direct-mapping has a cache of 2048 Blocks, where each block contains 32 words, and 2^30 words of main memory, . How many blocks of main memory are there? Assuming memory addressing starts from zero, what is the highest memory address? How many bits are needed to represent all of the memory addresses? What is the format of a memory address as seen by the cache, that is, what are the sizes of the tag, block, and word fields? To which cache block will the memory reference 0000A63F_16 map
