In order to reduce the pressure of data storage and transmission on satellite, researchers implemented a method of object region data extraction from remote sensing image in orbit. This method stores and downloads pixels of interesting region through interesting region labeling. But encoding data volume (EDV), hardware scale and real-time property (RTP) are difficult to be balanced. To solve this...
Nowadays the weak signal detection technology is necessary in scientific research field, in which the phase-locked amplifying technology is widely used in the field of weak signal detection because it can meet the requirements of high speed and high accuracy. System Generator software is adopted as a tool since System Generator can make the design more conveniently and efficiently. The design of each...
Increasing calculation speed without affecting pixel calculation accuracy in fast image processing algorithms using parallel computation was always needed but controlled by Amdahl's Law. In fact increasing number of processors uses same data bus reduces the speed and not allowing us to get the 20 times faster as we expected. As number of processors are limited due to sharing processors same data bus...
Correcting infrared camera distortion is necessary in target tracking and object recognition system. The existent FPGA algorithm didn't utilize sufficiently the advantage of the parallel processing and leaded to the results that a great deal of the system resources were consumed and the running speed was slowed down. The paper analyzed the existing problems such as serial structure in other algorithms,...
An electrical drive and electricity generation operation system of Switched Reluctance Motor (SRM) for electric vehicles based on FPGA was introduced. Focused on 3 kW six-phase 12/10 SRM, FPGA of Xinlinx has been employed to construct the digital controller, and the system could be applied to vehicles to realize the starting and generating capability. Experimental results indicated that this system...
