Abstract: A power delivery sub-system included in a computer system employs a primary voltage regulator circuit that generates a primary supply voltage on a primary power supply node. The power delivery sub-system also includes multiple bypass voltage regulator circuits that source corresponding bypass currents to a local power supply nodes in an integrated circuit. The integrated circuit includes multiple circuit blocks coupled to corresponding ones of the local power supply nodes, and multiple local voltage regulator circuits coupled to the primary power supply node. When a voltage level of a given local power supply node drops below a threshold value, a corresponding local voltage regulator circuit sources a supply current to the given local power supply node.

Abstract: A computing device provides a user recommendation according to one or more privacy protocols. The computing device sends to a server one or more encrypted recommendation requests for recommendation information relating to a set of items, where the recommendation requests are encrypted by a cryptographic key not accessible to the server. The server uses the encrypted recommendation requests and a recommendation data store to generate one or more encrypted recommendation responses that it returns to the computing device using at least one of the privacy protocols, which prevents the server from accessing the encrypted recommendation request and recommendation response. The computing device receives from the server the encrypted recommendation responses relating to the set of items and decrypts the recommendation responses. Then, the computing device generates a user recommendation relating to the set of items from the decrypted recommendation responses and provides the recommendation to the user.
