Abstract

Application verification is a key basic task for ensuring component independence. It involves a series of tests, assessments, and comprehensive evaluations of components before they are applied to equipment, to determine the maturity of component development and their suitability for usage. This paper introduces the component application verification work based on the astronautic data acquisition and encoder system, achieving 100% domestication of components and completing two key technological breakthroughs and innovations. The first is a design of an image compression algorithm scheme and an employment of H.264 image compression algorithm, using domestic FPGA to replace the original imported FPGA+DSP scheme. The second is an optimization of the acquisition and encoder precision algorithm, completing filter function based on domestic FPGA. After verification, the image compression effect of the FPGA is better than that of imported products. The statistical compressed image peak signal-to-noise ratio is greater than 30dB, meeting the requirements for usage.
