Super-H emulator
The type of processor and its options are controlled at config time.
A huge part of the code is generated auto-magically by the lua code in auto; this allows for automatic generation of documentation, instruction implementation code, decoder code and assembler code.
Configuration files
These files, in ini format are responsible for controlling the generation of the library.
They accept values referring to other values from past sections in the format %section.key%
config.ini
This file contains the general configuration, such as the emulated processor and MPU, the program name, version and release mode, the naming convention of the functions and types as well as what code to generate.
deps.ini
This file contains the top-level dependencies of the designated target, that is, the functions and types that the target should export to the user.
files.ini
This file contains the list of all the templates used by the auto-magical generator. It is responsible for converting a function or type name to a filename on disk.
Supported models
See the models and mpus folders
- SH1
- SH2
- SH3
- SH4
- soon SH4A
- potentially SH3-DSP
- potentially SH2A if I find a way to handle dual-word instructions
ToDo list
- implement all instructions
- then check for the NOP code to invalidate the pipeline
- implement peripherals according to the spec
- implement assembler and disassembler
- implement a debugger
Building
To build, you should first edit config.ini to target a specific processor model and MPU.
Then, you should go into the auto folder and execute auto.lua with a Lua interpreter (tested with lua5.3).
Then, when the code is generated, you should go into the output folder and execute make to compile the generated code. This will generate all the target you specified in the config file.
