基于虚拟化的软件定义DSP计算技术研究
Research on Software Defined DSP Computing Technology Based on Virtualization
摘要
Abstract
With the rapid growth of space-based computationally intensive tasks,the demand for computing in onboard tasks has also sky-rocketed.Spaceborne computer systems typically use heterogeneous electronic systems,with their"computing power"enclosed in independent onboard computers,where computing resources cannot be shared with each other,leading to resource waste.Additionally,various embedded software and programmable logic use non-standard programming,which does not support unified upgrades and com-prehensive calls.To address this issue,a software defined DSP computing architecture based on virtualization technology is designed with heterogeneous CPU and DSP computing resources as the research focus.By analyzing the current challenges of abstraction and multi tenant technology,and drawing on virtualization technologies related to heterogeneous GPUs and FPGAs,technologies such as hardware abstraction layer,time division multiplexing virtualization,interface call redirection,component registration,and data routing are compre-hensively utilized,the multi user sharing and efficient unified invocation of DSP heterogeneous computing resources is realized.Experimental verification shows that software defined DSP computing architecture can achieve flexible decoupling of software and hardware in spaceborne heterogeneous computing systems,and support multiple users and applications accessing and calling a single DSP computing resource simultaneously.关键词
