摘要
System ACE主要用于多FPGA系统对高效空间、预置、高密度配置需求的解决方案中。本文充分利用了System ACE的MPU控制器接口,突破了其传统的应用环境,将其使用在DSP系统中。主要介绍了System ACE原理、CF卡原理,并深入分析了FAT文件系统存储机制,最终实现了DSP通过System ACE对CF卡的存储数据进行文件系统管理的目的。
System ACE is mainly used in multiple FPGA systems for a space-efficient, pre-engineered, and high-density configuration so lution. This article makes full use of the System ACE controller interface of the MPU, breaks through its traditional application environment, and uses them for file system design in the DSP system. System ACE principles, CF card principle and an in-depth analysis of the FAT file system storage mechanism are described. File system management of the data stored on CF card by DSP through System ACE is achieved.
