Write a program that converts or calculates values. use the following guidelines to write your program:

think of a program that requires you to convert or calculate at least two types of values. some examples may include converting between inches and centimeters or calculating distance.
write a function to perform the calculation. be sure to double check the formula and units. for example, does the equation require meters but your value is in feet?
determine a set of at least three values to test your program. be sure to include integers, floating point, negative, and positive numbers if appropriate.
create output to display the results of the testing.
write the pseudocode for this program. be sure to include any needed input, calculations, and output.

What are procedures that keep a data base current

Consider a byte-addressable computer with 16mb of main memory, a cache capable of storing a total of 64kb of data and block size of 32 bytes. (a) how many bits in the memory address? (b) how many blocks are in the cache? (c) specify the format of the memory address, including names and sizes, when the cache is: 1. direct-mapped 2. 4-way set associative 3. fully associative

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?
