Tools & docs for the TI DSP TMS57070 including IDA disassembler

See the wiki tab

TMS57070_disasm.py

• Install in IDA_dir/procs/
• Developed for IDA 7.0/7.2
• Not complete - currently missing:
  • Some addressing modes
  • Some opcodes (to be implemented)
  • Some opcodes (to be discovered)
• Issues:
  • Data references are basically broken. They don't point to the right place in memory (PMEM rather than CMEM or DMEM) and don't track read/write properly
  • CMEM loading from file is partially broken. IDA doesn't fully understand the idea that this segment has a different word size (3 bytes vs 4 bytes for the code section)
  • If a loop is broken (by undefining code), the loop instruction (or last instruction of the loop) may need to be re-analysed to restore the loop
  • Some indirect address incrementing modes cannot be displayed (such as incrementing the DMEM pointer when the instruction doesn't read/write to DMEM)
  • Auto-comments spam the output window with errors. But hey, at least you get auto-comments (no thanks to IDA's poor documentation)
  • Reloading the input file is broken. IDA ruins the database in the process, but doesn't actually load in the new data.

• Developed in Visual Studio 2019 as a console project
• Pretty good accuracy and support
• Tested against the real hardware in an automated process
• Main omissions:
  • Some XMEM functionality
  • Some flag functionality
  • MACC accuracy with large numbers
  • Good command line interface
  • A readme!
• WAV file input and output courtesy of https://github.com/audionamix/wave
  • MIT license in the main file "wave/file.h"

Arduino project for sniffing host interface traffic, for the purpose of dumping the PMEM and CMEM. For more information, see the readme

Arduino project for TMS57070 interfacing and Qt project for TMS57070 control via the PC. Features:

• PMEM and CMEM live upload
• CMEM live view
