摘　　要：在片上系统(System On Chip,SoC)芯片中,直接存储器访问(Direct Memory Access,DMA)用于处理大量数据,但很少考虑对其内部信号的保护。本文提出了一种新的DMA控制器硬件架构,该架构结合了错误码纠正校验(Error Correcting Code,ECC)算法来增强数据保护。通过对DMA控制器在不同情形下的仿真验证,证实了本文所设计的系统切实可行,能够实现单比特数据错误自动纠错、多比特数据错误报告,对于车载SoC可以提供一定的参考价值。In System On Chip(SoC)architectures,Direct Memory Access(DMA)is extensively utilized for handling large data volumes,yet internal signal protection within DMA is often neglected.This paper introduces a novel DMA controller hardware architecture that incorporates Error Correcting Code(ECC)algorithms to enhance data protection.This architecture is evaluated through simulations of the DMA controller under various scenarios,confirming the practicality and viability of the designed system.The system effectively achieves automatic correction of single-bit data errors and reporting of multi-bit errors,providing a certain reference value for vehicular SoC applications.
