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.

Installation:

Clone the repository:

git clone https://github.com/RealBusinessAccount/SplitBit-Emulator.git
cd SplitBit-Emulator

Build the Emulator: You'll need gcc and make or similar.

make

Run the emulator:

./SplitBit Programs/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.

Additional Info:

For more information on the custom ISA and programming for SplitBit, see the Programming Manual.
