  • Publication number: 20190004594
    Abstract: A server system including an enhanced Network Interface Controller (NIC) within a client-server architecture is provided. The server system includes a memory for storing data from one or more network packets and one or more processors for processing network requests based on the one or more network packets. The enhanced NIC is configured to receive the one or more network packets and transfer the data from the one or more network packets to the memory. During a latency period defined from the time required to transfer the network packet to memory, the enhanced NIC performs a Network-driven, packet Context Aware Power (NCAP) management process in order to actively transition a power management state of the one or more processors to a predicted level. In this manner, computational and energy efficiency of the server system is improved.

  • Patent number: 9959205
    Abstract: An architecture for improved memory access in asymmetric memories provides a set of shared row buffers that may be freely allocated between slow and fast memory banks of the asymmetric memory. This permits allocation of row buffers dynamically between the slow and fast memory banks to improve execution speeds and also permits a lightweight memory swap procedure for moving data between the slow and fast memory banks with low processor and memory channel overheads.
