Exercise 3: The Hack Computer (All together)
(Covering Teaching Weeks 7-9)
[ GROUP Submissions are Assessed, worth 20%]
Introduction
In total, the coursework (lab work, split into multiple submissions, and assignments) is worth
50% of your final mark.
This exercise has TWO parts, as you can see below. But first, in Task 0, you need to download
the files required for this exercise, which specifies the folder structure and names for the
submission.
Task 0: Download Files [ALL]
Ex3-Files.zip provides all the sekelton .hdl and .asm (as well as most of the related tst and cmp
files).
 Download the Ex3-Files.zip file, from the “Exercise 3” area on moodle.
 Extract the files and fill in the required HDL and Assembly codes, as per the tasks in this
document (both part1 and part2, in there respective folders).
 MAINTAIN the same folder structure, file names, and all test & compare files, when you
submit. You can add any additional files you may need to get your submissions working
properly.
Marking note
 See the associated “Marking Sheet”, on moodle, for the breakdown of marks.
 You are allowed to use Built-in chips, for chips/gates already done in the previous exercises
and/or any auxiliary chips that you may need (except any of those that are required, to be
developed, in this exercise 3 itself).
 All chips & code will be tested through testing scripts.
 Marks of this Ex3 submission will be modified by multiplying by a factor from the VIVA process,
which can heavily affect the final mark (depending on the demonstrated understanding of the group &
individuals in the viva)
This exercise has TWO parts.
COMP1027 – Computer Fundamentals

Part 1: Assembly Code [ 35% of Ex3 marks]
In this part of the assignment, you are required to provide two Assembly
programs (for the HACK computer) to the following tasks:
a. An Assembly code that does Multiplication: [GROUP]
 Implement a multiplication Assembly code that multiplies R1 (RAM[1]) and
R2 (RAM[2]) and stores the result in R3 (RAM[3]).
Hint: Obviously, there is no multiplication instruction/code to use (the underlying
ALU can only add numbers). So, how do you perform a multiplication for two
numbers A and B? Well, you can just add A for B-numbers of times. For example,
if B is 3, then A x B is the same as A + A + A. Here, you would treat A as a stored
constant while B is a variable that you keep track of.
 If you make no progress. Why don’t you implement the “algorithm” in CLanguage
and use what you learn from the “Addition” example, demonstrated in
details in the lecture and lab, to come out with the corresponding machine code for
this task.
b. An Assembly code that does Factorial: [GROUP]
o Implement an Assembly program to calculate the factorial of a given
number n, F(n). A factorial of a number is given by:
F(n) = n*(n-1)*(n-2)*......*2*1
o The user should enter the value of the number n into R0. i.e. RAM[0]
o The factorial result F(n) should be saved in RAM[1].
SUBMISSION: SUBMIT your answers, i.e., completed Mult.asm and Factorial.asm
files (and all associated tst and cmp files).

Part 2: The Hack Computer [65% of Ex3 marks]
Context, Description, and suggestions:
 In the previous exercises and lab sessions, we used combinatorial and sequential logic
circuits to construct many of the various core logic circuits that form the basis of a CPU and
Memory.
 This exercise concludes all the effort by completing the construction of the Hack computer,
i.e. putting it all together and have the Hack Computer working & executing instructions.
o Firstly, The Memory will be built according to the Hack architecture.
o Secondly, the CPU will combine the ALU and other circuits. But you’ll need to
develop the “Control Unit” that manages the data flow and execution of instructions.
o Finally, all are connected together as one chip (the “Computer”)
o You should go through Lecture slides, Chapter 5 and Appendix A of the primary text
carefully.
 More lab reading resources are available at www.nand2tetris.org/05.php. In particular, go to
the Resources subsection, download “Chapter 5” (and relevant appendices).
 Note that for this exercise, all tasks are made in Group work. You are encouraged to break
your group into subgroups, each working on a different task. You should finish your tasks
faster this way. However, you must maintain communication between subgroups, that is,
every single member is expected to be able to explain the design & implementation for each
individual task (this will be verified during the VIVA examination, after the submission).
NOTEs:
 Do not worry if you didn’t manage to complete any of the previous exercises, or your
implementation (from previous exercises) doesn’t work correctly since nand2tetris provides
built-in implementations (implemented in Java) of all the required chips. To ensure you use
these built-in implementations, we recommend you keep the files for this exercise away from
the previous exercises (and you MUST maintain the provided folder structure).
All files, for Part2, will be under ONE folder (i.e. NO Sub-folder
under Part2). Please see & stick to the provided zip file & its folder
structure & file names
Task A: Memory [GROUP]
 Implement the Memory chip.
Hint: The specification for the memory chip is described in the lecture and Chapter 5. Note
that you would have to use RAM16K, Screen, and Keyboard ‘parts’ (built-in, but you should
refresh yourself with its interface specifications in Chapter 5, for the latter two).
COMP1027 – Computer Fundamentals

 If you make no progress. You need to understand what makes a memory chip – there is this
need for addressing/selecting “memory banks”. How do you select between 3 outputs
(RAM16K, Screen, Keyboard)? (Mux4Way*? DMux4Way*?). You still need to
interpret/decode a 15-bit address and pass them through to the right “memory banks”
(RAM16K, Screen, or Keyboard). The memory addresses are already given to you (e.g.
lecture slides, and Chapter 5). The ‘logic’ for interpretation/decoding would make more sense
once you convert them to binary. You would note that only certain address bits are crucial for
selection.
SUBMISSION: SUBMIT your answers, i.e., completed Memory.hdl file (and associated tst
and cmp files).
Task B: CPU [GROUP]
 Implement the CPU chip.
Hint: This may be the most challenging task – So, give it enough attention. The CPU
implementation (framework) is given in the lecture and Chapter 5, Section 5.3.1. In general,
the CPU as a complex logical gate would fetch and execute instructions in their
corresponding A- and C-Instruction codes (16-bits long).
 If you make no progress. Look at the Chip diagram of CPU implementation in the lecture
and in Chapter 5. Adopt a divide-and-conquer approach, that is, try to solve the problem by
parts. Use this skeleton and compare with the Chip diagram:
// Instruction decode
// Use a combination of elementary logical gates to decode the instructions
// You should first decode between A and C-Instructions,
// then the computation and destination
.
.
And (a=cInst, b=instruction[4], out=destD);
.
.
// A register and input mux
Mux?? (…);
?? (…);
ARegister (…);
// D register
DRegister(in=aluOut, load=destD, out=dReg);
// ALU and input mux
Mux16 (…);
ALU (…);
COMP1027 – Computer Fundamentals

// PC with jump test
// Use a combination of elementary logical gates to implement the truth table for jump
// functions, given in lectures.
// For example, try to figure out why one implementation would make use of:
// Or (a=jle, b=jgt, out=jmp);
.
.
PC (in=aReg, reset=reset, inc=true, load=jmp, out[0..14]=pc);
NOTE: the above pseoudo-code is for illustration purposes only. It may NOT be complete/accurate for the HDL
similar. You only use it as a guide/hint.
SUBMISSION: SUBMIT your answers, i.e., completed CPU.hdl file (and associated tst and
cmp files). You are also required to submit a full circuit diagram of your CPU implementation.
Task C: Computer [GROUP]
 Implement the Computer chip.
Hint: This is easy, and as a bonus only 3-lines of code:
CPU (inM=??, instruction=??, reset=??, writeM=??, outM=??, addressM=??, pc=??);
Memory (in=??, load=??, address=??, out=??);
ROM32K (address=??, out=??);
 The provided zip file contains couple of test files (e.g. ComputerMax, ComputerAdd,
ComputerRect), to test your Computer chip. Make sure to utilize them and properly test your
chip before submission.
SUBMISSION: SUBMIT your answers, i.e., completed Computer.hdl file (and associated
tst and cmp files).

FINAL SUBMISSION INSTRUCTIONS
1. For All Tasks, students are required to work in small groups (as listed).
2. Each group will have ONE submission ONLY (by one nominated member of the group).
3. The nominated member, for each group, should notify us about the submission and indicate
which group he/she represents.
4. We reserve the right to ask all/some students to explain any/all of their submitted work at
any time. Failure to answer/respond appropriately could affect your marks.
5. The group submission must be submitted through Moodle as a ZIP archive containing all
the requested files (same folder structure as per the downloaded file). The ZIP file should
be named as CSF-Ex3-XX.zip, where XX is the Group Number.
6. NOTE about the Compressed File:
a. Use .ZIP format ONLY (any other compression formats is NOT acceptable and will
result in you losing marks for not adhering to instructions).
b. Compress the whole folder structure/tree only (see the provided zip file, for an
example). i.e. Avoid compressing each individual folder/file. Nested compression will
prevent the marking process and could result in marking scripts failing, and hence
losing a lot (if not all) of marks.
Click on the “Exercise 3” link under “Coursework Submission”. Take note of the
Deadline 22nd November 2020, 22:00.
Any submission after this will be subject to the usual penalty rule.
There will be a VIVA (oral examination) after the submission. The result of
the viva could highly affect the final mark of the group and individuals
(depending on the demonstrated understanding in the viva).
