1. Calculate the z-scores (to two decimal places) for each observation and write the answers in the last column on the table above.
2. According to Chebyshev’s Theorem, what percentage of the observations should be within 1 standard deviations of the mean? (Hint: be sure to word your answer correctly.) For this question, you do not need to use any data—this is a purely theoretical question asking what Chebyshev predicts for this situation.

Management is concerned about the continued losses shown by the racing bikes and wants a recommendation as to whether or not the line should be discontinued. The special equipment used to produce racing bikes has no resale value and does not wear out. Required: 1. What is the financial advantage (disadvantage) per quarter of discontinuing the racing bikes? 2. Should the production and sale of racing bikes be discontinued? 3. Prepare a properly formatted segmented income statement that would be more useful to management in assessing the long-run profitability of the various product lines.

Let x be a random variable representing percentage change in neighborhood population in the past few years, and let y be a random variable representing crime rate (crimes per 1000 population). A random sample of six Denver neighborhoods gave the following information. x 26 1 11 17 7 6 y 172 36 132 127 69 53 In this setting we have Σx = 68, Σy = 589, Σx2 = 1172, Σy2 = 72,003, and Σxy = 8920.

C Programming Assignment 4

Cache Simulation

Objective:

To write a C program that simulates reading and writing to a custom-sized direct-mapped cache, involving a custom-sized main memory.

The program will read all values from the ZyLab as Test Bench inputs.

Main Menu Options:

The program simulates reading from and writing to a cache based on choosing from a menu of choices, where each choice calls the appropriate procedure, where the choices are:

1. Enter Configuration Parameters
2. Read from Cache
3. Write to Cache
4. Quit Program

Note that when you read from ZyLab, the input values are not displayed on the screen as they are in the sample run at the end of this document.

Inputs:

• Enter Parameters
  • The total size of accessible main memory (in words)
  • The total size of the cache (in words)
  • The block size (words/block)
• Read from Cache
  • The main memory address to read
• Write to Cache
  • The main memory address to write
  • The contents of the address for writing to the cache

Input Value Checks:

• All the parameter values must be powers of 2.
• The block size must never be larger than the size of accessible main memory.
• The total cache size must be some multiple of the block size.
• Your program should verify that all input variables are within limits as they are entered.

Output Messages:

All messages should be display EXACTLY as shown in the sample run; that is, prefixed by three asterisks, a space and hyphen and one more space. The message should be followed by a blank line.   

• Data Accepted Message is comprised of two sentences:

*** All Input Parameters Accepted.

     Starting to Process Write/Read Requests

• Error Messages are preceded by “*** Error –“. A list of possible errors is given below.

Note that one message has been deleted from previous versions of this Specification and three new ones have been added.

*** Error - Main Memory Size is not a Power of 2

*** Error - Block Size is not a Power of 2

*** Error - Cache Size is not a Power of 2

*** Error – Block size is larger than cache size

• Deleted Error Message

*** Error – Cache Size is not a multiple of Block Size

• Newly Added Error Messages

*** Error – Read Address Exceeds Memory Address Space

*** Error – Write Address Exceeds Memory Address Space (The write value following the invalid address value should be read and then discarded)

*** Error – Invalid Menu Option Selected (Until configuration data has been accepted, the only valid menu options that can be entered are “1” or “4.”)

Whenever any one of these errors occurs, the program should loop back to the Main Menu.

• Content Message resulting from reading/writing to the cache

*** Word WW of Cache Line LL with Tag TT contains Value VV

This message should appear after all successful reads or writes

WW is the word number in the cache line, LL is the line number in the cache, TT is the line’s tag value and VV is the content value in the cache.

All values are in decimal.

• Read Messages (two possible messages)

*** Read Miss - First Load Block from Memory (followed on the next line by the Content Message above)

*** Cache Hit (followed on the next line by the Content Message above)

• Write Messages

*** Write Miss - First Load Block from Memory (followed on the next line by the Content Message above)

*** Cache Hit (followed on the next line by the Content Message above)

• Quit Program Message

*** Memory Freed Up – Program Terminated Normally

When option 4 is entered, the memory should be freed up and the message “Memory Freed Up – Program Terminated Normally”, followed by a blank line, should be displayed before exiting the program.

Program Requirements:

• Use a structure (struct) to represent a cache line consisting of a tag (integer) and a block (integer pointer). Define the cache to be a pointer to the struct.
• Upon entering the parameters, the main memory and cache are to be dynamically allocated (use malloc) based on their respective total sizes.

Each word i of main memory is initialized with the value M–i, where M is the size of main memory in words. So, memory location 0 will contain the address of the last memory location and the last memory location will contain the address of the first memory location (i.e. 0).

• Reading/writing from/to a new block in the cache results in dynamically allocating a block for that instance, based on the previously entered block size.

Prologue & Comments:

At the very beginning of your source code (the very first lines), please include a prologue which looks like the following:

/*

Programming Assignment 4: Cache Simulation

Comp 222 – Fall 2019

Meeting Time: 0800-0915       (your meeting time)

*/

• Include simple (brief) comments strategically throughout your program so that someone else can readily follow what you are doing, but don’t overdo it. Examples might look like these:

// Reading input values from ZyLab

// Determining the contents of memory

ZyLab Test Benches:

• You will be permitted unlimited submission attempts on ZyLab until the due date. Afterwards, the inputs will be changed, the point value of the assignment will be increased to 100 and only one submission will be permitted. This last submission will be on the day following the due date and should be the one with the highest score.

• Hardcopy printed listing of your program. Please place this on the Professor’s desk at the beginning of class on day the assignment is due. It should be properly C formatted listing and not one from programs such as Word.

Make sure your full name appears on each page of the listing and that all pages are stapled together in their correct order BEFORE you come to class.

Failure to provide this listing will result in no grade for the assignment.

The following is a sample run of one of the tests in Assignment 4’s Test Bench on ZyBooks. Note: Some recently added error conditions are not included in this run.
