A New Generation of Platforms for CDAS
Abstract
A new platform was finished by the end of 2013. It contained two Xilinx K7 FPGAs for data processing, in addition to the capability of supporting two channels that each sample 512 MHz bandwidth or a single channel that samples 1024 MHz bandwidth. Compared with the previous platform, which consists of four Xilinx V4 FPGAs, the new one not only updates the key chips for DSP but also adds two 10-Gigabit Ethernet SFP+ ports for data transmission. The new platform also improves the performance and lowers the cost.
