In the analysis of an ARM binary, when would one normally encounter transfer operations between memory and a coprocessor? These are encoded as the `LDC` and `STC` operators.

Would it be common for programs to have this functionality or is it more specific for system-related operations? Any insight would be helpful, thanks in advance.
