What is an advantage of multiprocessor architecture? - correct answer it increases
throughput.
In which type of multiprocessor is latency to any word in main memory the same
regardless of which processor requests access? - correct answer uniform memory
access
Which computer architecture idea is analogous to the assembly line? - correct answer
performance via pipelining
What is an advantage of using virtual memory technique? - correct answer it permits a
program to exceed the size of primary memory.
What is an advantage of implementing cloud computing? - correct answer it provides
automatic scaling.
What is the bit width of an simd register with the suffix of 'd' when determining subword
parallelism? - correct answer 64-bit
Which register holds the result for the instruction
Sub x1, x2, x3? - correct answer x1
Register m0 should contain the result of dividing register r1 by r2. R1 and r2 contain two
unsigned 32-bit integers.
Which arm instruction is optimized for this arithmetic operation? - correct answer udiv
m0, r1, r2
, Which benefit does pipelining a set of instructions provide? - correct answer the
throughput of the complete set of instructions is increased.
Given four sets of arm instructions that take the same amount of time and processing
power to execute.
How much faster would the instructions complete if executed 1,000 times using a
pipelining methodology? - correct answer 4 times
What is improved from all legv8 instructions having the same 32-bit length? - correct
answer pipelining
What is the address of the next instruction that should execute after the branch if the
register x1 is equal to 0?
28 sub x12, x4, x8
32 cbz x1, x5, 5
36 and x13, x4, x7
40 orr x14, x4, x8
44 add x14, x6, x4
48 sub x15, x8, x9
52 ldur x4, [x7,#50] - correct answer 52
How can the cpu performance of a program be improved? - correct answer by
reducing the number of clock cycles
A program runs alone on a cpu. The cpu clock rate is 3e9 cycles per second, i.e., 3 ghz.
It takes the cpu 15e9 clock cycles to complete the program. The cpu clock cycle time is
500e-12 second, i.e., 500 picoseconds.
