What makes myhexadecimalnumber a child of mynumber? which methods does myhexadecimalnumber inherit directly from the mynumber class? what can an instance of the mynumber class do? what can an instance of the myhexadecimalnumber class do? which methods are overridden? why are they overridden? how many examples of overloading are there? why was this done? where is the super keyword used? what is it doing? why isnβt the incoming value set immediately in the second myhexadecimalnumber constructor? how many examples can you find of an inherited method being called?

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, 2Δβ, 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 1.5Δβ 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?
