  • Publication number: 20230253337
    Abstract: Embodiments that allow both high density and low density interconnection between microelectronic die and motherboard via. Direct Chip Attach (DCA) are described. In some embodiments, microelectronic die have a high density interconnect with a small bump pitch located along one edge and a lower density connection region with a larger bump pitch located in other regions of the die. The high density interconnect regions between die are interconnected using an interconnecting bridge made out of a material that can support high density interconnect manufactured into it, such as silicon. The lower density connection regions are used to attach interconnected die directly to a board using DCA. The high density interconnect can utilize current Controlled Collapsed Chip Connection (C4) spacing when interconnecting die with an interconnecting bridge, while allowing much larger spacing on circuit boards.

    Abstract: Power management techniques are disclosed. For instance, an apparatus may include a bidirectional voltage converter circuit, and a control module that selectively operates the bidirectional voltage converter circuit in a charging mode and a delivery mode. The charging mode converts a voltage provided by an interface (e.g., a USB interface) into a charging voltage employed by an energy storage module (e.g., a rechargeable battery). Conversely, the delivery mode converts a voltage provided by the energy storage module into a voltage employed by the interface. Other embodiments are described and claimed.

  • Patent number: 11700130
    Abstract: Logic may implement protocols and procedures for vehicle-to-vehicle communications for platooning. Logic may implement a communications topology to distinguish time-critical communications from non-time-critical communications. Logic may sign time-critical communications with a message authentication code (MAC) algorithm with a hash function such as Keccak MAC or a Cipher-based MAC. Logic may generate a MAC based on pairwise, symmetric keys to sign the time-critical communications. Logic may sign non-time-critical communications with a digital signature. Logic may encrypt non-time-critical communications. Logic may append a certificate to non-time-critical communications. Logic may append a header to messages to create data packets and may include a packet type to identify time-critical communications. Logic may decode and verify the time-critical messages with a pairwise symmetric key. And logic may prioritize time-critical communications to meet a specified latency.
