AppliedMicro’s initial ARM-based SoC design will be optimized for cloud server systems with a software-friendly architecture that greatly improves system utilization. AppliedMicro has implemented a sophisticated microarchitecture for the ARMv8 64-bit ISA and optimized it to deliver the highest performance while maintaining the power and cost profile associated with ARM technology. This server-on-a-chip will integrate multiple copies of AppliedMicro’s ARMv8 compliant 64-bit cores and a high-performance terabit coherent fabric with on-chip 10-Gigabit LAN, storage and WAN physical layer IP, as well as a 100-Gigabit per second inter socket communications interface to extend coherency to multi-chip configurations. The SoC design integrates server-class dynamic power management to maximize power savings during the idle state while maximizing performance and responsiveness with the ability to configure thermal dissipated power (TDP) to meet varying system requirements. This technology allows the SoC to achieve an unprecedented level of standby power of less than 300mW.
The X-Gene’s unprecedented level of SoC integration in cloud server system designs reduces the chip count while also eliminating the power-hungry interfaces. In addition, the X-Gene platform is designed with Reliability, Availability and Serviceability (RAS) features required in the server space.
“We are excited to collaborate with AppliedMicro, who are early implementers of 64-bit ARM architecture based solutions,” said Lance Howarth, Executive Vice President Marketing, ARM. “As cloud computing continues to redefine high end computing workloads, highly integrated solutions like AppliedMicro’s server-on-a-chip will offer an optimized balance of power, performance and price for an emerging generation of efficient server solutions.”
AppliedMicro’s new processor family will leverage build upon the already large installed ARM software and hardware ecosystem and appeal to the open source software community much like its 32-bit predecessor. Server class open-source OS will be fully enabled by the time of production.First samples of AppliedMicro’s X-Gene server-on-a-chip devices are expected in the second half of 2012 and will be produced at TSMC.
