Prologue

Imagine a messenger service which delivers high$-$valued cargo to paying customers most of

whom are hospitals and urgent care medical facilities. One heavily serviced route goes from

Fullerton to Santa Ana from there to Long Beach, and finally returns to Fullerton. The driver of

the delivery van may select the physical streets The distance from the delivery service

headquarters in Fullerton to the first customer in Santa Ana depends on the route selected by

the driver of that day. A similar statement can be said for the route from Santa Ana to Long

Beach. We want an assembly program that will compute the average speed of the delivery van

for the entire trip.

Requirements

Make a hybrid program with the main module in C language and the computational module in

X$86$ modern assembly language. The structure adheres to the basic diagram shown below.

Definitions

The program of Assignment $1$ is the set of three modules represented by three rectangles in the

above diagram. The arrow points to a module that will be called by the earlier module.

For us in this class each module contains the source code of one function. In general

programming a module may contain multiple functions.

The language of the file r$.$sh is bash, witch is sometime written Bash.

Dialogue

When you are testing your program it should produce output like the following. We call the

output the dialog because the human user and the machine are communicating with each other.

Enter the number of miles traveled from Fullerton to Santa Ana: $15\mathrm{.}7$

Enter your average speed during that leg of the trip: $42\mathrm{.}6$

Enter the number of miles traveled from Santa Ana to Long Beach: $19\mathrm{.}2$

Enter your average speed during that leg of the trip: $53\mathrm{.}9$

Enter the number of miles traveled from Long Beach to Fullerton: $28\mathrm{.}2$

Enter your average speed during that leg of the trip: $64\mathrm{.}9$

The inputted data are being processed

The total distance traveled is $63\mathrm{.}10000000$ miles.

The time of the trip is $1\mathrm{.}15927445$ hours

The average speed during this trip is $54\mathrm{.}43059661$ mph$.$

The driver has received this number $54\mathrm{.}43059661$ and will keep it for future use.

Have a great day.

A zero will be sent to the operating system as a signal of a successful execution.

Color codes:

Yellow: driver function

Pink: average function

Green: user inputs

There are no integers in this program. All the numbers are floating point numbers stored in the

component of the CPU called SSE. Do not use any registers from the FPU component.

Notice that in the color scheme above main is not part of the algorithm that solves problem

presented in this document. The color scheme shows that main only performs a welcome

message and a good$-$bye message. This is a requirement.

The output from your program must match the output shown above in every character except

the numbers, which will be different. Main function does know anything about the problem being

solved by the assembly function.

All float number must be displayed with $8$ decimal digits on the right of the point.
