Abstract:

A flame work of a super-resolution imaging system with the non-conventional image-carrying fiber bundles which adopts DSP (DM642) and FPGA as the core is presented in this paper.The function of FPGA in the system,including bilinear interpolation of Bayer images,image format conversion between RGB and YUV,communication with USB controller and so on,are discussed in detail.In this system,the FPGA connects with video port of DM642 directly to transmit YUV color space image data.This communication structure is simple,but it can guarantee high rate of data transmission,DSP greatly reduced its workload by extracting Y component directly from the YUV color space data to compute.This system gives full play to the quickness of hardware implementation in FPGA and enhances the system capability;and it has such advantages as adaptability,and flexibility.
