  • Method and apparatus for updating a system on chip (SOC) image from a host computer system without using DMA
    Patent number: 9934120
    Abstract: Embodiments of the present disclosure relate to systems and methods for updating a System on Chip (SOC) image without using direct memory access (DMA) programming. A target SOC monitors a target mailbox to determine reception of a data packet of an SOC image received from a host computer, wherein the SOC image includes a plurality of data packets. The target SOC reads the data packet from a buffer of the target SOC and writes a status message to a host mailbox of the target SOC, wherein the status message is indicative of a reception status of the data packet.

  • Compression of IPV6 addresses in a netflow directory
    Patent number: 8015315
    Abstract: Modified flow keys holding compressed IPv6 addresses are stored in a flow table to improve memory utilization. The compressed IPv6 addresses are utilized to access a compression table holding the full IPv6 address, and full IPv6 address are substituted into the modified flow key to form an unmodified flow key.
