Abstract
The word-length of functional units (FU) has a great impact on design costs. This paper addresses the problem of choosing different word-lengths for each FU while considering circuit area and power consumption. A high-level synthesis tool is used to minimize the circuit area and power consumption by selecting an optimal word-length for each FU in the system. Our results demonstrate that by customizing word lengths to non-standard sizes, savings can be made in the overall area and power without losing accuracy
