Abstract

The obtained data are compressed and stored in hard disk at real time and uploaded to the personal computer simultaneously during the remote sensing of Spacecraft. ISP1761,which is USB chip with OTG(on-the-go) is introduced to realize protocol transform, and control host and Peripheral to switch. It dominates up and down high speed data transfer for settling the contradiction of duplicative roles that is host and peripheral of data compression board in the USB transfer. Virtex4 FPGA chip which contains MicroBlaze is adopted to fulfill initialization and DMA data transfer according to the capability of ISP1761. Data transfer is achieved at the speed of 46.9Mbps after the image is compressed by JPEG2000.
