| Abstract: | Software and hardware design of a acoustic signal processing system based on DSP and PCI bus was introduced in this article,its appications was also proposed.Data acquisition,signal processing and data storing in real-time were realized in this system which was divided into two modules:DSP and PCI.Data acquisition and signal processing were completed on DSP module.High speed data communication between PCI and DSP was implemented on PCI module using the bridge chip to share the dual-port RAM with DSP.Now thi... |
