Abstract: 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. 

Key words: digital signal processor (DSP), software stack, complier, debugger, independent chip
