Dataflow-based DSP Modeling And Timing Analysis Software Design

With the rapid development of the digital signal processing technology andembedded technology, the embedded DSP system in application fields become morewidespread. At the same time, embedded DSP system also become more and morecomplicated.The proportion of the development cycle and development costs is moreand more big.The traditional DSP software development process is modeling and simulation inmatlab simulation environment, then according to creating model, translating the modelinto C or assembly code in the visual dsp++environment in order to obtain thedownloadable and executable dsp code, and finally completing the verification inhardware. Unable to obtain directly executable code from the model, this makes dspmodeling and development disjointed and makes the development cycle anddevelopment costs increased. In order to solve these problems, this article has beendesigned set algorithm modeling, memory layout, code generation, time-series analysis,hardware debugging in the integrated system.This article mainly elaborates the system design principle, design functionarchitecture and each function introduction. On the basis of study on the time-seriesanalysis technology, this article describes the realization process of the system of modelanalysis and time-series analysis, and eventually generates timing view. Practice showsthat the system has good validity and practicability, can be applied to practical systemdevelopment.
