Abstract
A stack with a unary encoded stack pointer which uses the position of a single bit to point to the top of the stack. A number of multi-bit latches are used to store the data elements in the stack. A serial, bidirectional shift register is loaded with all digital zeros except for a position having a digital one (the pointer) which is coupled to the register containing the top of the stack. As new data elements are pushed onto or popped off of the top of the stack, the pointer is shifted right or left accordingly.
