Write a short block of computational statements that causes the cx register to set the carry flag. use variables as opposed to immediate values. make sure no other computations affect the outcome of this register. the register must be zeroed out before it is used. using directives for creating symbolics, write a single statement that computes the number of seconds in a day and places the result in the edx register. the statement that is placed in the program and expanded should be seconds_in_day. the edx register should be zeroed out before it is used. make

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?
