Embedded data acquisition hardware for high speed satellite data archival and processing

Abstract

To design an effectively fast and reliable high performance platform for satellite real time data acquisition, archiving and processing. A data acquisition system on a Programmable chip using the latest state of art technology FPGA, FIFO s and PCI-X 64bit/66MHz Master core is to be designed for acquiring multiple channel data from remote sensing satellites and can be interfaced to a true 64bit server for data archival and processing.It is planned to be designed for operating at frequencies ranging from 5MHz/sec to 200MHz/sec per channel. A short form standard Printer circuit Board adds on card is planned. Electrical inputs to the hardware are planned through Low voltage Differential Signaling. The power for the card will be drawn from the host system through PCI-X bus. The Embedded Data Acquisition Hardware is planned with PCI-X 64bit /66MHz DMA Interface to support both input channels in interleaved method. Data Acquisition board with Plug and Play features in PCI systems is planned. Frame Synchronization of the two channels, decommutation into 64bit word, writing the parallel data into the on chip memory at high speed of the on chip memory. Tagging the external GPS parallel data for every frame and transferring the data to a secondary onboard buffer for newlineinterfacing to the PCI 64bit/66MHz core. The core is to be integrated into the FPGA and by DMA mode, data transfers at a sustained rate of above 200 Megabytes /second is envisaged. newline
