Xilinx Inc. has introduced what it flaunts as the industry's first high performance DDR4 memory solution for All Programmable UltraScale devices running at 2400Mb/s. Based on an ASIC-class architecture, the UltraScale devices support massive I/O and memory bandwidth with dramatic power and latency reduction.

The DDR4 memory interface in UltraScale devices claims to provide more than 1Tb/s of memory bandwidth to handle the massive data flow, fast processing and enormous memory requirements of leading-edge, next-generation system designs in key applications such as video imaging and processing, traffic management and high-performance computing, stated Xilinx. Applications will see a reduction in read latency by 30 per cent and significant power savings at the same data rate by going from a DDR3 to DDR4 interface. Even more compelling, customers can realize a 30 per cent improvement in data rate while also benefiting from a 20 per cent reduction in power when moving from DDR3 at 1866Mb/s to DDR4 at 2400Mb/s.

These DDR4 memory interfaces are tested over stressful system conditions such as varying voltage and temperature, system-induced jitter and with difficult data patterns, to ensure operating margin for real system deployment. Compliant with the JESD79-4 DDR4 SDRAM standard, Xilinx's SelectIO interface helps ensure the greatest timing margin. To guarantee optimal signal integrity, the I/O technology includes transmit pre-emphasis, receive equalization, low jitter clocks and noise isolation design techniques.

UltraScale devices with DDR4 memory interfaces are available.
