22 | # Pitch
23 |
24 | There are two fundamentally competing forces when it comes to computer speed. The first, and most famous, is Moore's law, where physical transistor densities scale exponentially. The second is the inevitable growth of software bloat that runs on top of increasingly modern processors. There's a kind of equilibrium between these two competing beasts, ensuring that a user always manages to get at least a split second of mindfulness while staring at a frozen screen whenever attempting to open the latest app.
25 |
26 | This project is an attempt to score a decisive rout in this ongoing battle in favor of the *programmer*. By emulating a complete rv32i instruction set inside the wiring system of [Terraria](https://www.terraria.org/), we push back speeds to the early 70s era, tossing the ball firmly back into the court of the silicon engineer without losing any software functionality.
27 |
28 | # Overview

36 |
37 | Despite what the pitch may lead one to believe the goal of this project is to maximize the compliance and processing ability of the in game cpu. This is only possible with the help of an accelerator mod, which maintains full compatibility with the vanilla wiring system but reimplements it in a much more efficient manner:
38 |
39 | [WireHead](https://github.com/misprit7/WireHead) - A wiring accelerator and headless control mod
40 |
41 | With this installed, the current specs of the computer are as follows:
42 |
43 | - Clock speed: ~5kHz
44 | - Ram: 96kb
45 | - Instruction set: rv32i
46 |
47 | As an example of what it can do, here is Pong, running purely on the in-game cpu (see [app/pong/src/main.rs](app/pong/src/main.rs) for implementation):
48 |
49 | https://user-images.githubusercontent.com/33139843/229342342-de4708e1-7467-4f99-834b-3d0fb28d0858.mp4
50 |
51 | # Setup
52 |
53 | Note that currently only Linux is fully supported, and only parts of this have been tested on Windows. However I've left some steps for anyone who wants to try getting Windows working, in theory using wsl it should be fairly straightforward and things should be identical.
54 |
55 | ## Prerequisites
56 |
57 | For a comprehensive list of everything that is needed to run all aspects of this project, see the [Dockerfile](docker/Dockerfile). However, to develop and run applications for the computer all you really need is a working Cargo/rustc installation, install it [here](https://www.rust-lang.org/tools/install) or through your package manager.
58 |
59 | ## Setup Process
60 |
61 | Navigate to where you want to keep this project and clone it. Copy computer.wld to your tModLoader world path. Depending on your platform, this is:
62 | ```
63 | Windows: Documents\My Games\Terraria\ModLoader\Worlds
64 | Linux: ~/.local/share/Terraria/tModLoader/Worlds
65 | ```
66 | On Linux you can automate copying back and forth like this with the `copy-world.sh` script with either the `--to` (copy to world folder) or `--from` (copy from world folder) flags.
67 |
68 | Next, navigate to the mod sources folder and clone [WireHead](https://github.com/misprit7/WireHead):
69 | ```
70 | #Windows
71 | cd "%userprofile%\Documents\My Games\Terraria\ModLoader\ModSources" && git clone https://github.com/misprit7/WireHead.git
72 |
73 | #Linux
74 | cd "~/.local/share/Terraria/tModLoader/ModSources" && git clone https://github.com/misprit7/WireHead.git
75 | ```
76 |
77 | Prepare the binary you wish to run. For example for pong compile the rust app and copy the binary to a more convenient path:
78 |
79 | ```
80 | cd <path to computerraria>/app/pong
81 | cargo rb
82 | ./copy-bin.sh /tmp/pong.txt
83 | ```
84 |
85 | Start [tModLoader](https://store.steampowered.com/app/1281930/tModLoader/), and from the main menu go to Workshop->Develop and click on the Build button next to WireHead. For convenience I'd also recommend installing Cheat Sheet and HERO's Mod from the Download Mods section of the workshop if you haven't already. Then open the new world you copied earlier in game. In game type:
86 | ```
87 | /bin write /tmp/pong.txt
88 | ```
89 |
90 | Currently the NPCs that run the CPU clock are too far away to spawn immediately, this is a bug and should be fixed soon. As a workaround, go through the blue teleporter shown below, fly upwards a bit, come back down and go back through the same teleporter.
91 |
92 | 
93 |
94 | After this workaround is done, press the first two of the three levers on the far right to start the program. Go through the orange teleporter to arrive at the screen area. Pong should be running and is controllable by the controller beneath the screen (use HERO's Mod's camera lock to see the screen and controls at the same time).
95 |
96 | 
97 |
98 | ## Docker
99 |
100 | For advanced CI/headless usage you can use the docker image:
101 |
102 | [Docker Image](https://hub.docker.com/r/misprit7/computerraria)
103 |
104 | If you already have docker installed this can be pulled with
105 |
106 | ```bash
107 | docker pull misprit7/computerraria
108 | ```
109 |
110 | You can then start the container with
111 |
112 | ```bash
113 | docker run -it misprit7/computerraria
114 | ```
115 |
116 | This image already has all tooling installed so you should be able to build everything.
117 |
118 | # File Structure
119 |
120 | The major relevant parts of the project are as follows:
121 |
122 | ```
123 | .
124 | ├── app/
125 | │ ├── tdriver/
126 | │ └── template/
127 | ├── computer.wld
128 | ├── doc/
129 | ├── docker/
130 | ├── test/
131 | └── tinterface/
132 | ├── bin/
133 | └── tinterface/
134 | ```
135 |
136 | `app/`
137 |
138 | Higher level applications to be run on the computer, not including compliance tests. Currently all in rust but could also easily be in C.
139 |
140 | `app/tdriver/`
141 |
142 | Driver API for interacting cpu from rust, mostly extremely low level startup code and graphics drivers.
143 |
144 | `app/template/`
145 |
146 | Template for new rust projects that implements minimal tdriver
147 |
148 | `computer.wld`
149 |
150 | The actual world file. This is technically a binary file, but given the context of the project it acts much more like source code given that it is edited manually and compresses extremely well. This generally isn't edited in place, it's copied back and forth to the user installation with [copy-world.sh](copy-world.sh).
151 |
152 | `doc/`
153 |
154 | Documentation/notes for the project
155 |
156 | `docker/`
157 |
158 | Files required to build docker image for CI.
159 |
160 | `test/`
161 |
162 | All automated tests written for the CPU. These are mostly handled through [riscof](https://github.com/riscv-software-src/riscof). This consists of both the computerraria plugin as well as a reference plugin ([sail_cSim](test/sail_cSim/)) to compare the results to.
163 |
164 | `tinterface/`
165 |
166 | Interfaces programmatically with running Terraria instance. This consists of both a python module as well as a command line wrapper to upload binaries, start execution and manipulate other fine grain controls without needing a GUI.

1 | # Computerraria Rust Template
2 |
3 | This is a template for building Rust applications targeting [Computerraria](https://github.com/misprit7/computerraria).
4 |
5 | ## Setup
6 |
7 | To set up a new project, run the following:
8 | ```bash
9 | cp -r template PATH/NAME_OF_PROJECT
10 | cd PATH/NAME_OF_PROJECT
11 | sed -i s/template/NAME_OF_PROJECT/ Cargo.toml copy-bin.sh .vimspector.json
12 | cargo build --release
13 | ```
14 | To actually use the project, you can convert the file to the required [WireHead](https://github.com/misprit7/WireHead) file format with the provided script:
15 | ```bash
16 | ./copy_bin.sh /tmp/in.txt
17 | ```
18 | You can then load it into Computerraria with the following command, written in the in-game chat (NOT your terminal):
19 | ```
20 | /bin write /tmp/in.txt
21 | ```
22 | Once you start the clock the screen should update to be on in the outer horizontal border.
23 |
24 | ## Development
25 | The entrance point of the program is `main` in [`src/main.rs`](src/main.rs), make changes there. You can change the tick rate of the emulator in the `[env]` section of [`.cargo/config.toml`](.cargo/config.toml).

64 | 2: Right

66 |
67 | Notes on registers:
68 | - Use 32 bit binary tree multiplexer
69 | - Two logic gates per bit, 1 for loading and the other for storing
70 | - Duplicated binary tree to allow a read and write in one iteration
71 | - Can't easily allow two reads in one iteration, so instructions with rs1 and rs2 aren't allowed
72 |
73 | Notes on memory:
74 | - Massive binary tree structure for selection, bottom layer is load/store select
75 | - Address is cached both to deal with colour problems and because reads need two data bus inputs
76 | - Same memory structure as registers with 2 gates for each bit, although much more compact
77 |
78 | Notes on adder:
79 | - Could just use a 3 to 8 multiplexer for 1 bit adders, but I'd like something nicer
80 | - Output of adder is xor of all three inputs A, B and C which is implicit with wiring, carry is harder
81 | - Carry is determined with following equation: C_out = (A&B)^(A^B if C) which is easy to implement in faulty logic
82 | - To get subtraction simply invert B's bits to and set first carry for two's complement
83 | - In my implementation B is toggled back after operation, although since operands aren't expected to be reused strictly speaking this is unnecessary
84 |
85 | Notes on comparator:
86 | - Was lazy and didn't think through things myself: http://lumetta.web.engr.illinois.edu/120-S17/slide-copies/053-2's-complement-comparator.pdf
87 | - If dir is 1 then actually less than or equal, useful for conditional branches
88 |
89 | Notes on AND/OR/XOR:
90 | - Went for a super compact design
91 | - xor xors, and zeros then ands, or xors then ands
92 |
93 | Notes on equalitator:
94 | - Definitely not a word
95 | - Not part of original ALU requirements but is required for BEQ/BNE
96 | - Encoded as funct3=001, dir=1 since that's only free combination
97 | - Doesn't bother to zero other bits, so sets last bit 0 if neq and 1 if eq
98 |
99 | Notes on decoder:
100 | - Multiplexes opcodes out
101 | - Immediate loading is done as efficiently as possible by reusing common overlap
102 | - Load instr signal tells decoder to cache registers, functX, etc. so that data bas can be reused
103 |
104 | Notes on PC:
105 | - Increment loads as well to enable one clock cycle jumps
106 | - Wire colour scheme for increment has convoluted colour sharer circuit for previous design that tried to increment and load in one iteration
107 | - A bit of a mess, leaving as is for now since I might realize I've made a mistake in terms of pc loading timing
108 |
109 | Notes on aligner:
110 | - Not the best put together, kinda hacky
111 | - Completely undefined behavior for misaligned reads, be careful!!!
112 |
113 | Notes on control unit:
114 | - Instructions are responsible for incrementing pc since some instructions want to do that later or earlier
