Computer Architecture C952 Study Guide Graded A+

What is an advantage of multiprocessor architecture? {Ans: It increases throughput.}How can the CPU performance of a program be improved? {Ans: reduce number of clock cycles}Given this set of ARM instructions, where b is at offset 0, e is at offset 8, and a is at offset 24: LDUR X1, [X0,#0] LDUR X2, [X0,#8] ADD X3, X1, X2 STUR X3, [X0,#24] What is the corresponding C language statement? {Ans: a = b + e;}Overflow occurs when: {Ans: -you add two integer values with the same left most bit and end up with a different left most bit -when you subtract a value with a different leading bit than the other value, and the result is the first value's sign}SRAM {Ans: faster than dram and less dense than dram, it is an integrated circuit}A cache has 16 one-word blocks. Memory blocks are mapped to fully associative caches. Memory block is 15. What is the cache position given the cache configuration and memory block? {Ans: Any of the 16 blocks, since it is fully associated.}
