摘　　要：飞腾迈创DSP是国防科技大学计算机学院为了突破卡脖子技术,解决我国相关重点领域内芯片长久受制于人的现实问题而自主设计的高性能数字信号处理器。由于该系列芯片采用全自主设计的指令集,无法兼容已有的软件,一套自主完备且高效的软件栈是决定飞腾迈创DSP生命力的关键。基于团队长期以来的持续工作,系统阐述了飞腾迈创DSP软件栈的设计原则与层次化架构,重点介绍了包括支持层、编译层以及工具层在内的相关软件工具的创新功能、实现方法以及性能。同时,结合用户的反馈与团队的思考,还讨论了飞腾迈创DSP软件栈未来需要探索的相关问题。FT-Matrix DSP(Digital Signal Processor)is a high-performance digital signal processor designed independently by the College of Computer Science and Technology,National University of Defense Technology,to break through the key technology and resolve the long-standing problem of dependency on foreign-made DSPs in key areas in China.Because the series of FT-Matrix chips use a self-designed instruction set,they cannot be compatible with existing software.A self-sufficient,complete,and efficient software stack is crucial for determining the vitality of FT-Matrix DSP.Based on the team's accumulated work,this paper systematically explains the design principles and hierarchical architecture of the FT-Matrix DSP software stack,focusing on innovative functions,implementation methods,and performance of related software tools including support layers,compilation layers,and tool layers.Additionally,drawing upon user feedback and the team's insights,this paper also discusses relevant issues that need to be explored in the future development of the FT-Matrix DSP software stack.
