【摘要】：基于FPGA的可重構(gòu)系統(tǒng)設計是目前可重構(gòu)計算中研究較多的領域,可重構(gòu)計算同時具有軟件的靈活性和硬件的高性能,在嵌入式系統(tǒng)和高性能計算等領域獲得了越來越廣泛的應用,然而可重構(gòu)操作系統(tǒng)及其可重構(gòu)系統(tǒng)中任務自修復方面的研究仍是一個薄弱之處。 本文重點研究可重構(gòu)嵌入式系統(tǒng)的操作系統(tǒng)支持,主要在操作系統(tǒng)對軟硬件任務的支持和對任務級自修復特性的支持兩方面做以研究,包括以下幾方面的研究工作： 第一,介紹了一個擴展的Xilkernel,該操作系統(tǒng)完成對軟硬件任務的統(tǒng)一管理。首先,詳細說明了該操作系統(tǒng)對可重構(gòu)區(qū)域、硬件任務、位流文件、數(shù)據(jù)通信等管理的實現(xiàn),其次,介紹了該操作系統(tǒng)對外提供的統(tǒng)一多任務編程接口API的設計與實現(xiàn)。 第二,介紹了另一個擴展的Xilkernel,該操作系統(tǒng)同時支持軟硬件任務統(tǒng)一管理和硬件任務的心跳監(jiān)測。首先,詳細講述了該操作系統(tǒng)對可重構(gòu)區(qū)域、硬件任務、位流文件、數(shù)據(jù)通信等管理的實現(xiàn)；其次,介紹了硬件任務心跳監(jiān)聽器的設計和實現(xiàn)；最后,講述了操作系統(tǒng)對外提供的統(tǒng)一多任務編程接口API的設計與實現(xiàn),通過該接口用戶可創(chuàng)建軟硬件任務及配置心跳服務。 第三,我們分別在實驗室的硬件平臺和Xilinx ML505平臺上實現(xiàn)了兩個嵌入式系統(tǒng)：遠程動態(tài)可重構(gòu)嵌入式系統(tǒng)和可重構(gòu)自修復嵌入式系統(tǒng)來驗證兩個操作系統(tǒng)的正確性和性能。通過實驗可看出操作系統(tǒng)均可正確執(zhí)行,其中硬件任務比軟件任務有30倍以上的加速比。引入的心跳服務(100次/秒)對操作系統(tǒng)軟件線程執(zhí)行速度的影響也很小(0.3%-0.5%),對硬件線程的執(zhí)行無影響。
[Abstract]:The design of reconfigurable system based on FPGA is a research field in reconfigurable computing. Reconfigurable computing has the flexibility of software and the high performance of hardware. It has been widely used in embedded systems and high performance computing. However, the research on task self-repair in reconfigurable operating systems and reconfigurable systems is still a weak point. This paper focuses on the operating system support of reconfigurable embedded system, mainly in two aspects: the support of operating system for hardware and software tasks and the support for task-level self-repair characteristics. The research work includes the following aspects: firstly, an extended Xilkernel, operating system is introduced to complete the unified management of software and hardware tasks. Firstly, the realization of reconfigurable region, hardware task, bit stream file, data communication and so on are described in detail. Secondly, the design and implementation of the unified multitasking programming interface (API) provided by the operating system are introduced. Secondly, another extended Xilkernel, is introduced, which supports both hardware and software task unified management and hardware task heartbeat monitoring. Firstly, the realization of reconfigurable region, hardware task, bit stream file, data communication and so on are described in detail. Secondly, the design and implementation of hardware task heartbeat monitor are introduced. Finally, the design and implementation of the unified multitasking programming interface (API) provided by the operating system are described, through which the user can create software and hardware tasks and configure the heartbeat service. Thirdly, we implemented two embedded systems on the lab hardware platform and Xilinx ML505 platform: remote dynamic reconfigurable embedded system and reconfigurable self-repairing embedded system to verify the correctness and performance of the two operating systems. The experiment shows that the operating system can be executed correctly, and the hardware task is more than 30 times faster than the software task. The introduced heartbeat service (100 beats per second) has little effect on the execution speed of the operating system software thread (0.3% -0.5%), and has no effect on the execution of the hardware thread.
