+ +## πŸ“ Overview +This program is a simulator for the [ICMC architecture](https://github.com/simoesusp/Processador-ICMC/). It features several upgraded functionalities compared to the C++ simulator, including: + +- A resizable window and fullscreen capability. +- An instruction scroll to view all instructions and data being modified in real-time. +- Ability to edit the stack pointer and program counter directly. +- Enhanced error handling: the simulator will halt and indicate errors to the programmer. +- Improved parsing of MIF files, adhering strictly to syntax definition and providing detailed error messages. +- Capability to change character mapping MIF during runtime (without resetting). +- Shortcuts that do not rely on keys that may not be present on laptop keyboards (e.g., insert, home, and end keys). +- Support for Windows, macOS, and Linux. + +## πŸ’» Installation +If you prefer not to compile anything, you can download a precompiled binary for your system from the [releases page](https://github.com/lucasgpulcinelli/goICMCsim/releases). + +## πŸš€ Usage +To get started, add a program to run and test it. You can specify MIF files in the ICMC architecture format in the command line or use the file -> open code/char MIF menu.

Choose an opcode for your instruction. +2. Add it to the constants list at [processor/Instruction.go](processor/Instruction.go). +3. Below the constants list in the same file, add your instruction data to the `AllInstructions` list. This allows the simulator to find and execute your instruction. +4. You need to provide four pieces of information: + - The opcode you just created. + - An instruction to generate its mnemonic string.
