In this work we present the design of an FPGA based platform for acquiring and storing signals for SDR applications. The system comprises an embedded RISC processor, an A/D converter, RAM memory chips and a DMA controller core. This last component was designed from scratch to meet the high data rate and bulk requirements. The software needed to control the system was also developed and a Graphical User Interface was written to allow a user to interact with the system from a host PC. The developed system was successfully used for offline processing the received signals of a GNSS RF front-end.
