Helicopter with its flexible, mobile, high-speed low altitude flight capabilities play a significant role in the military, but because of its load capacity constraints, requiring radar system versatility, including target search, tracking, recognition, collision avoidance and other functions. During the war, the helicopter usually with trees, terrain, man-made objects as a cover by the radar system on the target search, track, and then identify and confirm the blow. Radar Display and Control Terminal Among these played a huge role, because the radar terminal directly with the operator interface to provide information to the operator must be done intuitive, accurate, real-time, and must have a friendly user interface, Eli radar operation control. This topic uses high-performance PowerPC processor MPC8540, for the radar display and control terminal application, the design of a generic radar display and control terminal platform, designed to build the radar display and control software development, hardware support and a powerful platform support, so that the software write generic and platform. The platform has been successfully applied to multiple radar systems. Radar display and control terminal hardware platform integrates ARNIC429, RS422/485, CPU expansion bus, PAL-D interfaces, 1553B, synchronous serial interface, and other hardware interfaces, these interfaces are connected to each unit and the corresponding realized various types of equipment inter-communicate. Modern radar display and control terminals have become increasingly demanding, requires not only a powerful processing capability, power consumption, etc. volume weight is more stringent requirements. PowerPC architecture in terms of performance, frequency and low power consumption and other aspects of an effective balance. MPC8540 processor integrates IEEE 802.310/100/1G Ethernet controller; 1 10/100M Ethernet controller; a 64-bit PCI-X controller, operating at frequencies up to 133MHz; a DDR controller; 4-channel DMA; Multi-channel interrupt controller. MPC8540 highly integrated to make the design more stable and reliable. Meanwhile MPC8540 processor integrates 256KB L2 cache, SIMD (Single Instruction Multiple Data) extensions, single-precision floating-point unit, DSP instruction acceleration unit, enhance the overall performance of the CPU, the CPU running at 800MHz, can reach 1850MIPS Performance (P Ⅲ 1GHz about 900MIPS), while consuming only 6W. As with real-time embedded Linux strong graphics capabilities to support good development of the difficulty small, low-cost characteristics, so the radar display and control terminal, we use the embedded Linux operating system.
