Electro Optical Tracker System Based On Digital Singnal Processor And CAN

The studies the application of digital signal processor, site local bus in vehicular photoelectric system in communication control. Analysis of the advantages of digital signal processor, site local bus, clear the use of digital signal processor and field local bus in vehicular photoelectric system advantage. The field bus has the data between nodes is strong real-time, short development cycle, strong anti-interference ability, high efficiency, high security features. Separate digital signal processor program and data space, can also access instructions and data, through the data bus independent in the two block visit at the same time, has low overhead or no overhead circulation and jump hardware support, fast interrupt processing and hardware I/O support, with operations in a single cycle, multiple hardware address generator you can perform multiple operations, support pipelining parallel, the fetching, decoding and execution can be characterized by overlapping the execution, convenient interface, good stability, high precision, easy integration, convenient programming etc.. This paper presents the hardware design scheme in detail, overall scheme design software application. And according to the proposed hardware, software realization scheme of the data communication board production. Through the function test of the scheme is feasible, and has been applied in a plurality of photoelectric system, achieved the objective economic benefit.
