Consider the following ARMv8 assembly code:

START: ADD X0, X1, 0

ORR X2, XZR, 1

ADD X3, XZR, XZR

LOOP: CBZ X0, FINISH

AND X4, X0, X2

LSR X0, X0, 1

EOR X3, X3, X4

B LOOP

FINISH: ADD X5, X3, 0

BR X30

What value is left in X5 after the execution of this code?

Assume that X0 = 9 and X1 = 8 at the start of execution.

Under which key category do the page up and page down keys fall? page up and page down keys fall under the keys category.

For a typical middle-income family, what is the estimated cost of raising a child to the age of 18? $145,500 $245,340 $304,340 $455,500

When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. for example, if we put in a complicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. the basic amdahl's law equation does not take into account this trade-off. a. if the new fast floating-point unit speeds up floating-point operations by, on average, 2ă—, and floating-point operations take 20% of the original program's execution time, what is the overall speedup (ignoring the penalty to any other instructions)? b. now assume that speeding up the floating-point unit slowed down data cache accesses, resulting in a 1.5ă— slowdown (or 2/3 speedup). data cache accesses consume 10% of the execution time. what is the overall speedup now? c. after implementing the new floating-point operations, what percentage of execution time is spent on floating-point operations? what percentage is spent on data cache accesses?
