Reliable High Speed Data Acquisition System Using FPGA

This paper presents design and implementation of a data acquisition system (DAS) in field programmable gate arrays (FPGA) using system on chip (SoC) methodology. To ensure the reliability of data being transmitted over the channel, a suitable framing interface along with error detection is proposed and interfaced with Xilinx Aurora IP core. The proposed DAS is capable of transmitting the data @ 1.25 Gbps over the channel. The main advantage of the proposed DAS is that the configuration and monitoring is done using the in-built PowerPC processor of FPGA through universal synchronous asynchronous receiver transmitter (UART). This type of DAS is suitable for multi channel acoustic data acquisition and in Electronics Warfare systems.
