Abstract

A lookup table is a permanent memory storate element in which every stored value corresponds to a unique address. Range addressable lookup tables differ in that every stored value corresponds to a range of addresses. This type of memory has important applications in a recently proposed central processing unit which employs a multi-digit logarithmic number system that is well suited for digital signal processing applications. This thesis details the work done to improve range addressable lookup tables in terms of operating speed and area utilization. Two range addressable lookup table designs are proposed. Ideal design parameters are determined. An integrated circuit test platform is proposed to determine the real-world ability of these lookup tables. A case study exploring how non-linear functions can be approximated with range addressable lookup tables is presented.
