# SplitBit Emulator
|
|
|
|
## Overview:
|
|
SplitBit is a custom CPU designed for hobbyist projects and experimentation. The SplitBit Emulator is a C implementation of its bespoke instruction set architecture. It allows users to load and run binary programs created for the SplitBit CPU interactively from the command line.
|
|
|
|
### Features:
|
|
- 8-bit Harvard Architecture: The system memory is separated into two 64k banks, one for the Program Memory and another for the Data Memory.
|
|
- Custom ISA: A fully implemented instruction set architecture optimized for simplicity and easy assembly programming.
|
|
- Debug Mode: Single-step through instructions and monitor the CPU's registers as they change through each cycle.
|
|
- CLI Based: Debug messages and CPU input and output are supported through the command line.
|
|
- Binary File Support: Load programs and data from binary files.
|
|
- Modular Codebase: Mostly clean separation of CPU, I/O, and utility functions for easy modification.
|
|
- Assembler: Assemble human readable assembly language files directly into SplitBit compatible binary files. Supports including external files, handling labels, and defining Program and Data segments.
|

|
|
### Installation:
|
|
1) Clone the repository:
|
|
```
|
|
git clone https://github.com/RealBusinessAccount/SplitBit-Emulator.git
|
|
cd SplitBit-Emulator
|
|
```
|
|
2) Build the Emulator and the Assembler: You'll need gcc and make or similar.
|
|
```
|
|
make
|
|
```
|
|
3) Assemble a program:
|
|
```
|
|
./Assembler Programs/hello.asm
|
|
```
|
|
|
|
4) Run the program:
|
|
```
|
|
./SplitBit hello.bin
|
|
```
|
|
|
|
### Usage:
|
|
```
|
|
./SplitBit [options] [binary file]
|
|
```
|
|
#### Options:
|
|
- -d, --debug: Enable debug mode to single step through cycles.
|
|
- -h, --help: Show help and usage information.
|
|
|
|
### Usage:
|
|
```
|
|
./Assembler [assembly file]
|
|
```
|
|
#### Notes:
|
|
- The assembled binaries are saved with the same name as the assembly source file they're assembled from, with a .bin extension, in the same directory that you call the assembler from.
