Abstract


With the development of information technology , path planning technology is widely used in various types of navigation systems , such as unmanned aerial vehicles , robots , and so on to play a crucial role in modern penetration . Therefore, to improve the planning system security , accuracy and diversity of the general trend of the development of today 's flight path planning system . There are a variety of existing planning methods based the track fragments planning method used in this article is cell decomposition and roadmap methods combine . Large amount of computation and very time-consuming step of restructuring of the track after track fragments generated in the method and fragments generated . In order to speed up the planning process , the use of a DSP parallel processing methods to assist in the planning . Research in parallel processing system using a the three TI 's high-end chip TMS320C6455 the custom bus interconnection can be articulated through the PCI bus to the host , you can also communicate through a Gigabit Ethernet interface to keep up with bit machine . This paper first analyzes the characteristics of the track fragments planning system and clarify the feasibility of parallel co-processing methods to help the host planning . Multi-DSP system hardware structure of the framework , and highlights the system's PCI module and the Gigabit Ethernet module . Then introduces the PCI bus and the WDM driver model structure , and for the TMS320C6455 PCI module use DriverWorks tool development and design of WDM (Windows Driver Model) driver . Followed from the universal applicability of the network analysis the DSP system communicates with the network trend which points out the special nature of the TCP / IP protocol in the DSP system . Network development tools NDK, TI's DSP / BIOS system to achieve the design of the network driver . Finally , the driver will be used in the flight path segment in the planning system , and experimental results are given to realizing the data analysis .
