ARM Instruction

This is the ARM instruction interface, every new instruction must implement this interface.

Instructions are contained in the armsim.instruction package.

There we have the following modules:

• dp.py Data Processing instructions
• branch.py Branch instructions
• ldstr.py Memory load and store instructions
• mult.py Multiplication instructions
• semaphore.py Semaphore instructions
• status.py Status Register operation instructions
• exception.py Exception generating instructions
• miscellaneous.py Miscellaneous instructions

Most of the instructions are recognized, but it is yet needed to implement most of this instructions, if you would like to help check the Contribute page
