| Abstract: | This paper presents the development of DSP in recent years as well as the wide range of application. The comparison between float DSP method and fixed DSP method is made in several aspects such as operation accuracy, error index as well as the function and performance of the corresponding processing system. Some viewpoints are put forward about how to improve a DSP system. |
