This program uses the timers to trigger EDMA events. These events in turn * trigger linked EDMA parameter tables to fill a ping pong buffer structure. * Set a breakpoint on swiProcessFunc(int arg). Then open two memory windows. * Use ping as the address for one memory window and pong for the other. Then * run the application. You ll note that the program bounces between the ping * and pong buffers filling each with a value that comes from the source. The * source in this case is the SDRAM timer control register and it simulates * input data(This program uses the timers to trigger EDMA events.

NXP LPC11xx 系列单片机IAP在线升级的研究。经过长时间的摸索，研究LPC1114 IAP在线升级，因此写下文档记录方便以后查阅，同时也给需要IAP在线升级的同仁提供参考。文档内容是实践过的，经过多次反复测试(NXP LPC11xx series MCU IAP online upgrade. LPC1114 IAP online upgrade after a long period of exploration, research, write a convenient documented after inspection, but also to the need to IAP online upgrade colleagues to provide a reference. Document content is practice, after repeated testing)

次源码是用C++实现的jpeg图像压缩程序，压缩倍数可控制，压缩质量较好。

用四叉树实现了LOD地形的绘制，当然，是四叉树，如果有需要了解的话，或者是想要做场景管理开发的话，建议必备，呵呵！其他的就不多说啦！代码才是真功夫！祝下载者体验愉快吧！(Use quadtree realized LOD terrain rendering, of course, is quad-tree, and if there is a need to know about it, or want to make scene, necessary management development, hehe! Other did not say! Code is true effort! Wish downloaders experience enjoyable!)

针对粒子概率假设密度(PH D)滤波算法在虚警、漏检情况下，b标状态估计不稳定和b标可观测性车弱的问题，提出了一种基于序贯融合的粒子PH D滤波方法，利用雷达和红外传感器多目标进行融合跟踪杏基本思想是先对红外传感器进行粒子PH D滤波，丙将红外传感器滤波结果作为雷达的预测值，然后利用P达观测的数据进行更新，这样通过雷达和红外传感器交替上作保证目标状态的可观测性，从滤波器输出结身即可得到目标的状态信息仿真结果表明，在虚警、漏检和密集目标环境下，该方法是有效的和稳健的(The problem of target state estimation instability and observability weakerin the presence offalse alarms and missed detection was deal with. On the basis of sequential fusion, a particleprobabil- ity hypothesis density(PHD) filter for multrsensor multrtarget tracking was proposed. Observed da to collected from the infrared sensor was estimated with the particle PHD filter. Then the results from the filter were set as the radar predicted value by the radar observations. The multrtarget state can be updated to guarantee observing the target state. In this way, the global state is updated at the fusion center. Simulation results show that the proposed algorithm is effective and robust under the false warning, omission and concentrated target environment. )
