Short Content: Abstract: The enlargement mode direct memory deposits and withdraws (EDMA) is in digital signal processor (DSP) uses in the fast data exchange the important technology, has the independence in CPU backstage batch data transmission ability, can satisfy in the real-time imagery processing the high speed data transmission request. Take TI Corporation's TMS320DM642 DSP as the example, introduces the EDMA controller's characteristic. The union example gives EDMA and realizes the method in the image data live transmission concrete control. The experimental ...
