Systems and methods may provide for receiving a Reverse Polish Notation (RPN) program stream including a set of operands and a set of operations and populating a first register stack with one or more operands in the set of operands. Additionally, one or more registers in the register stack may be powered off based on a stack depth of the register stack. In one example, one or more arguments are read from the register stack and an execution is conducted of one or more operations on the arguments.
