Innovational Stack Pointer

Abstract

A method and apparatus to generate the read/write pointer of the stack or the last in first out memory (LIFO) is proposed. We use the linear feedback register (LFSR) to replace the traditional counter to generate the read/write address for the stack. Its’ advantage is more efficient and costs lower circuit area overhead. Besides, due to the pseudo random sequence of the LFSR, we make encryption to the data written to the stack (PUSH) and the burst error can avoid when we read data from the stack (POP).
