Automated Conversion of SystemC Fixed-Point Data Types

TL;DRAbstract

This article describes a methodology for the automated conversion of SystemC fixed-point data types and arithmetics to an integer-based format for simulation acceleration and hardware synthesis. In most design flows the direct synthesis of fixed-point data types and their related arithmetics is not supported. Thus all fixed-point arithmetics have to be converted manually in a very time-consuming and error-prone procedure. Therefore a conversion methodology has been developed and a tool enabling an automated conversion of SystemC fixed-point data types as well as fixed-point arithmetics has been implemented. The article describes the theory and transformation rules of the conversion methodology, their implementation into a tool solution, and its application in terms of an experimental case study.
