The resolution and frame rate of the video captured by the current camera arrays is not high enough to create the high quality 3DTV programs. We designed and implemented a high resolution camera array. It can be used to capture the video whose frame rate was 27fps and resolution was 1280×1024, or which frame rate was 93fps and resolution was 640×480. The two capture schemes can be chosen by the user applications. Some issues about the architecture, camera unit, synchronization control and real-time storage of the camera array were presented.

A dual-core DMA communication method between DSP and FPGA based on reverse wave analysis was proposed. In high definition and real-time dualcore embedded systems for catadioptric omnidirectional imaging, the dual-core DMA communication method was used to provide high speed panoramic data communication between DSP and FPGA. Reverse engineering methods were applied to perform reverse wave analysis on traditional DMA operations, and dual-core DMA communication was accomplished according to the results of wave analysis. Experiments indicate that the proposed dual-core DMA communication method provides a maximum data transmission speed between DSP and FPGA at 4.704Gbps (i.e. 588MBps).
