Started refactoring to a library-based model to easily integrate comprehensive unit testing. Added CPU exception handling system for the GUI. Non-critical exceptions (though critical to execution of emulated application) will not shutdown the application in the future releases. Refactored Userspace::Run() logic so that the GUI-controls reflect emulator behavior.
CPU Security Emulator [x86]
This is mostly a learning project for me. I am learning about the internals of a CPU and how it encodes/decodes instructions to produce the intended results.
As of now, there are limitied features, and supported instructions are limited.
See; https://0xinfinity.dev/specs/emulator for an exhaustive list of supported instructions and specific opcodes.
Planned emulator features
- SIB Byte Support for existing and future instructions.
- Execution Lock and Permission system for RAM.
- Branch Prediction and Speculative Execution //Long-term plan
- SIMD flattening (optional) and AV redirection (optional).
- Buffer overflow prediction, detection, and reporting.
Planned architectural features
- Better logging system
- Comprehensive unit tests for each instruction.
Planned instructions
TBD
Requirements
- gcc Rest; TBD
