A Dalvik-powered phone. The relative merits of stack machines versus register-based approaches are a subject of ongoing debate. [17]Generally, stack-based machines must use instructions to load data on the stack and manipulate that data, and, thus, require more instructions than register machines to implement the same high-level code, but the instructions in a register machine must encode the ...
