| Abstract: | This paper presents a high speed acquisition system based on key processor DSP TMS320VC5402. The system can collect data from multichannel analogue signal, and the sample rate of each channel at the same time is up to 1 MHz. After the real-time operation of the high speed processor, the data are transferred to upper main control computer through PCI local bus, where they are operated and analyzed further. The system can be applied to the high speed data acquisition and operation situations from multichannel analog signals. |
