-- List of definitions for every instruction
-- Each instruction definition contains:
-- Mnemonic: The mnemonic used to generate the assembler definitions and instruction list.
-- This is what must literally appear in the assembly code in order to generate this instruction, other than immediate values.
-- "imm8" means an 8-bit value.
-- "imm16" means a 16-bit value.
-- Opcode: The machine code byte that represents this operation.
-- Used by the assembler generator to map mnemonics to opcodes.
-- Used by the microcode generator to place the instruction's data within the microcode ROM, which is addressed by opcode.
-- List of control signals: Specifies the control lines that will be activated by the microcode when the instruction is executed.
-- Instructions may take multiple clock cycles. To convey this, each clock cycle is represented by an independent list of microcode signals.
-- Under the hood, the microcode ROM uses a 10-bit address: 8 bits for the opcode, and 2 bits for the clock cycle.
-- Because of this, each opcode may only use up to 4 clock cycles.
-- If more are required, the least significant bit of the opcode can be set by a control line, incrementing the opcode.
-- This causes one instruction to use up multiple opcodes.
-- The need for this is determined automatically by the microcode generator: whenever an instruction specifies more than 4 lists of control signals.
-- Description: A brief description of the instruction. Used to generate the instruction list.
-- C Code: Used to generate an emulator (as part of a separate project).
-- Categories can be specified. These serve only to organize the instruction list.
-- The category letter determines what letter will be used to represent the instructions in the opcode map, located at the bottom of the instruction list.

## Boot ROM
Execution starts here, at address `$0000`.<br> ## Main RAM
The main program is located here, or the OS bootloader if an OS is present. 8 KiB of random-access memory.<br>
Located at addresses `$8000` to `$9FFF`.<br>
Programs can write data to these addresses, and retrieve the data at a later time.<br>
Machine code can also be stored here and executed.
## Text Display
Write ASCII values to addresses `$2000` to `$27FF` to display characters at certain positions on the screen.<br>
`$2000` is the top left, `$27FF` is the bottom right.<br>
Rows are 64 bytes long.<br>
For example, `$2040` would be the first character of the second row from the top.<br>
Values can also be read back out of the display memory, as if it were RAM.
## Text Display Color
Write 6-bit color IDs to addresses `$0C00` to `$0FFF` to set the color of characters on the screen.<br>
If the most significant bit is 1, the character and background colors will be inverted, i.e. highlighted.<br>
Values can also be read back out of the display color memory, as if it were RAM.
## Main ROM
1 KiB of read-only memory.<br>
Located at addresses `$0000` to `$03FF`.<br>
When the CPU is first turned on, or is reset, it will start executing code from here, starting at address `$0000`.<br>
Bricks can be physically placed on top of the ROM brick to set bits within the ROM.<br>
A bootloader, operating system, or hex monitor may be loaded here.
## GPIO ## GPIO
Contains hardware multiplication (`$0400 * $0401 -> $0400`) and division (`$0402 / $0403 -> $0402 r $0403`), popcount (`$0404 -> $0404`), and a timer (`$0405`).<br> Contains hardware multiplication, division, popcount, and a timer.<br>
Value written to timer register = number of game ticks (32 ms) between interrupt triggers.<br> When two 8-bit values are written to the multiplier registers `$0400` and `$0401`, the result will be available as a big-endian 16-bit value at `$0400`. Read from `$0401` to retrieve an 8-bit result.<br>
Write 0 to disable. When two 8-bit values are written to the divider registers `$0402` and `$0403`, the quotient can be read from `$0402` and the remainder from `$0403`<br>
When any 8-bit value is written to the timer register `$0404`, the popcount of that value (The number of bits that are 1) can be read from the same location.
When any value is written to the timer register at `$0405`, an interrupt will be triggered after 32 milliseconds.
## Keyboard ## Keyboard
Read address `$0500` to get the next key event<br> Read address `$0500` to get the next keycode from the buffer.<br>
7-bit Windows VKey code, MSB 1 = press, 0 = release<br> Keycodes are 7-bit Windows VKey codes, plus a press/release bit. If the MSB is 1, the event is a key press; if 0, a release.<br>
Returns 0 if buffer is empty. Result will be 0 if the buffer is empty.<br>
Write 1 to `$0500` to enable keyboard interrupts, 0 to disable. If 1 is written to `$0500`, an interrupt will be triggered whenever a key event is available. Write 0 to disable again.
## Serial Peripheral Interface ## Serial Peripheral Interface
Not yet implemented. Not yet implemented.
## Robot Controller ## Robot Controller
Write to `$0701` to control the robot. Each bit is an action - MSB to LSB: Plant brick, destroy brick, move forward, backward, left, right, up, down.<br> Write to `$0701` to control a 1x1f-sized "robot" that can place and destroy bricks.<br>
Write a 6-bit color ID to `$0700` to set the color of the bricks the robot plants.<br> Each bit indicates an action; if that bit is set, that action will be taken. From MSB to LSB: Plant brick, destroy brick, move forward, backward, left, right, up, down.<br>
Read `$0700` to get the color of the brick the robot is on. MSB = brick exists. Returns 0 if no brick. Write a 6-bit color ID to `$0700` to set the color of the bricks the robot will plant.<br>
Read `$0700` to get the color of the brick the robot is currently overlapping. If the MSB is 1, a brick exists at this location. Result will be 0 if no brick is present.<br>
The robot should only be given new actions once per game tick. The timer at `$0405` can be used for this purpose.
## Text Display
Write ASCII values to `$0800` to `$0BFF` to display characters at certain positions on screen.<br>
`$0800` is top left, `$0BFF` is bottom right, rows are 64 bytes.
## Text Display Color
Write 6-bit color IDs to `$0C00` to `$0FFF` to set the color of characters on screen.<br>
MSB = whether to invert character mask (i.e. for highlighting).
## System RAM
The OS may use this memory for the stack, system variables, etc.<br>
If no OS is present, this memory can be used for any purpose, etc.<br>
Located at `$1000` to `$1FFF`.
## User ROM

# 8608 - An 8-bit data, 16-bit address, CISC architecture. # 8608 - An 8-bit data, 16-bit address, CISC architecture.
For a list of instructions, see [instructionList.txt](instructionList.txt). For a description of the architecture and a list of instructions, see [instructionList.txt](instructionList.txt).
## How to use the assembler: For a memory map of the 8608-based computer, see [memoryMap.md](memoryMap.md).
1. Install `bllua3` from [https://notabug.org/redo/bllua3](https://notabug.org/redo/bllua3)
2. Download this repo into `Add-Ons/8608` or anywhere within one of Blockland's main directories.
3. In BL console, execute:
```
luaexec("Add-Ons/8608/assembler-8608.lua");
```
4. To assemble a program, place a 1x1f ghost brick on the top-left corner of the ROM, face forward, and in BL console do:
```
AssembleBuildFile("Add-Ons/8608/examples/program.asm", "RomX RomY RomZ");
```
where `RomX` is the width of the ROM, `RomY` is the depth front to back, and `RomZ` is the height in bits, i.e., "16 16 8".
You can also run the assembler from the command line to get a memory dump and disassembly in stdout, if you have lua installed: To assemble programs, use CustomAsm: [https://github.com/hlorenzi/customasm](https://github.com/hlorenzi/customasm)<br>
``` Simply include the 8608 architecture file into your program: [8608.asm](8608.asm).<br>
luajit "Add-Ons/8608/assembler-8608.lua" "Add-Ons/8608/examples/program.asm" `#include "8608/8608.asm"`
```
## How to use the emulator:
1. Install love2d from [https://love2d.org](https://love2d.org)
2. Open a command prompt in the "emulator" folder and run:
```
love . C:/path/filename.asm
```
