基于DSP的DMA控制技术

DMA controlling technology based on DSP

通过分析TMS32 0C2XX使用保持 (HOLD)操作的直接存储器访问 (DMA)和DMA控制器 82 37- 5的工作原理 ,解决了DSP与 82 37- 5的软、硬件接口问题 ,实现了DMA在数字化语言学习系统中的应用。

After analyzing direct memory access(DMA) with HOLD operation in TMA320C2XX and the operation principle of DMA controller 8237-5,the software and hardware interface problem between digital signal processing(DSP) and DMA controller 8237-5 is solved, then DMA application in digital language studying system is achieved.
