Construction of the experiment teaching platform based on freescale DSP

An experiment teaching platform has been built based on the Freescale MC56F8346 type DSP(Digital Signal Processor,DSP).FPGA is used to expand the GPIO(General Purpose Input and Output,GPIO)of the DSP.In addition motor,communication and human-computer interaction modules are added in the peripheral circuit.So the platform can not only complete motor control,digital-to-analog conversion and other common hardware experiments but also can complete classic signal processing experiments such as FIR filtering,FFT transforming.Experiments like standard current loop output which is closely integrated with the practical application of engineering are also in count.This experiment system will offer great help to deepen the understanding on relevant expertise for both undergraduate and graduate students.The platform has been successfully used in undergraduate experiment teaching and achieved good teaching effect.
