With the structure of Digital Signal Processor (DSP) application program getting more complex, there is a rise in the need for concurrent access to shared resources under a multitasking environment. However, the task scheduling and synchronization provided by most of the DSP operating systems is quite limited, which can barely meet the requirement of the control of concurrent access. At present, reader-writer...
For the bearing track correlation problems of multi-sensor on the same platform, in this paper an algorithm for bearing track correlation is presented based on grey incidence analysis. In this algorithm each track's azimuth information is considered as a discrete function of time. The grey incidence analysis for multi target track's azimuth information is performed by using the degree of grey incidence...
In this paper, the DMA transfer tactics is used to optimize a packed/planar video format conversion program. The program method to employ the DMA transfer in the video processing algorithms will be present in this paper. The objective is to develop the efficiency of the DSP on loading the large image data, which are stored in the external memory. The synchronous problem of the DMA transfer data flow...
