For this question you will create an object to store information on an inventory of cars. Create a class called CarInventory Instance Attibutes: n_cars : int cars : list Methods add_car() compare() Details: The constructor (__init__) should take no inputs, but set n_cars to 0, and cars to be [] (an empty list). Method: add_car Input(s): manufacturer : string model : string year : int mpg : float Procedure(s): Create a dictionary from the values passed with the corresponding keys 'manufacturer', 'model', 'year' and 'mpg' Append this dictionary to the cars attribute Increment the n_cars attribute by 1 Method: compare

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?
