I'm afraid you misinterpreted the parent. The parent is saying that C's function calls and stack management are not implemented in hardware. That there is, in effect, a C 'runtime' that implemented these behaviors. Further, malloc and free are not hardware calls. The physical property would be literal ram addresses (not virtual memory, though there is now hardware virtual memory so i digress.)
