The IGLOO2 architecture offers up to 3.6x gate count implemented with the 4-input look-up table (LUT) fabric with carry chains, giving 2x performance, and includes multiple embedded memory options and mathblocks for digital signal processing (DSP). High-speed serial interfaces include PCI express (PCIe), 10 Gbps attachment unit interface (XAUI) / XGMII extended sublayer (XGXS), plus native serialization/deserialization (SerDes) communication, while double data rate 2 (DDR2)/DDR3 memory controllers provide high-speed memory interfaces.
