- main library
|
|
- [processor related](processor_general.md)
|
|
- operand: defines basic operand types used in instructions
|
|
- matcher and decoder: decodes binary instructions into opcodes and operands
|
|
- disassembler: translate binary instructions to (pseudo-)assembly.
|
|
- parser: translate (pseudo-)assembly to binary instructions
|
|
- interpreter: executes instructions
|
|
- [register](register.md): defines all register states in the processor
|
|
- processor: wrapper of interpreter and register as a processor emulator
|
|
- test_generator: generates test cases information for the instruction set
|
|
- peripherals
|
|
- [AHBM](ahbm.md): interface for accessing external memory (DSi/3DS main memory)
|
|
- [APBP](apbp.md): interface for communication with CPU (ARM in DSi/3DS)
|
|
- [BTDMP](btdmp.md): audio input/output ports
|
|
- [DMA](dma.md): engine for transferring large data between DSP memory and external memory
|
|
- [ICU](icu.md): interrupt controller unit
|
|
- [timer](timer.md)
|
|
- [MMIO](mmio.md): I/O ports for all peripherals
|
|
- shared_memory: the DSP working memory
|
|
- [memory_interface](miu.md): the memory space exposed to the processor and related control
|
|
- Tools
|
|
- coff_reader: disassembles and parses symbols COFF files leaked by some DSi applications
|
|
- dsp1_reader: disassembles DSP1 files, DSP binary for 3DS applications
|
|
- makedsp1: assembles DSP1 files
|
|
- test_generator: generate random test cases for processor instructions.
|
|
- mod_test_generator & step2_test_generator: similar to test_generator, but dedicated for mod/step2 related instructions
|
|
- test_verifier: verify test cases on the interpreter against the result generated from 3DS
