TY - JOUR T1 - Model-based precision analysis and optimization for digital signal processors JF - Proceedings of the European Signal Processing Conference Y1 - 2011 A1 - Kedilaya, Soujanya A1 - Plishker,William A1 - Purkovic, Aleksandar A1 - Johnson, Brian A1 - Bhattacharyya, Shuvra S. AB - Embedded signal processing has witnessed explosive growth in re-cent years in both scientific and consumer applications, driving the need for complex, high-performance signal processing systems that are largely application driven. In order to efficiently implement these systems on programmable platforms such as digital signal processors (DSPs), it is important to analyze and optimize the ap- plication design from early stages of the design process. A key per- formance concern for designers is choosing the data format. In this work, we propose a systematic and efficient design flow involving model-based design to analyze application data sets and precision requirements. We demonstrate this design flow with an exploration study into the required precision for eigenvalue decomposition (EVD) using the Jacobi algorithm. We demonstrate that with a high degree of structured analysis and automation, we are able to analyze the data set to derive an efficient data format, and optimize important parts of the algorithm with respect to precision.
