Suppose you are an excellent web application programmer and you have just been employed by a credit finance company. Few months after your engagement, your boss inform you about management’s decision to maintain a high public image as the leading savings and Loans Company in Ghana. He also said they were torn between developing it in-house and hiring AmansaWebs a reputable computer software solutions provider with an excellent record of web application development in the country to execute this task. Write to your boss, the IT Director convincing him that you have the critical knowledge necessary to execute this task to management’s satisfaction.

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?
