MDOS makes frequent use of XOPs and offers them for user programs. An XOP (extended operation) is a special command of the TMS processor family which causes a context switch, transferring control to a location that is specified in a table.
Compared to common architecture concepts, the XOP is TI's way of implementing a system call.
