Abstract
A last-in first-out data stack is able to store a plurality (n) of elements wherein the plurality is greater than two. For each of n storage locations in the stack a selector is adapted to receive n elements read out from the stack and a new element. The selector is arranged to make a controllable selection of its received elements. Combinational logic capable of performing logic manipulations on the selection of elements provides a resultant for pushing onto the stack.
