The invention provides a system and method for executing a replacement selection algorithm embedded in each associativity of a cache memory architecture. Each associativity in a cache has an internal control logic that governs the process for replacing a cache line when a certain condition occurs, such as a presence of a TagHit. A designated set of control signals is used in an associativity control logic for corresponding with an external control logic. An associativity control logic within an associativity provides an internal capability to determine whether a TagHit condition occurs as well as volunteering the associativity for replacement. The preferred replacement algorithm is implemented using an approximation to Not the Most Recently Used Associativity (NMRU).

The invention provides a cache architecture that selectively powered-up a portion of data array in a pipelined cache architecture. A tag array is first powered-up, but the data array is not powered-up during this time, to determine whether there is a tag hit from the decoded index address comparing to the tag compare data. If there is a tag hit, during a later time, a data array is then powered-up at that time to enable a cache line which corresponds with the tag hit for placing onto a data bus. The power consumed by the tag represents a fraction of the power consumed by the data array. A significant power is conserved during the time in which the tag array is assessing whether a tag hit occurs while the data array is not powered-on at this point.

According to one exemplary embodiment, a structure comprises an electronic device situated over a substrate of a semiconductor die. The structure further includes a metal cage comprising a number of contacts situated over the substrate and surrounding the electronic device. The contacts form a lateral EMI shield portion of the metal cage. The structure also includes a number of vias connecting a number of metal interconnect segments to the contacts. The metal interconnect segments form a top EMI shield portion of the metal cage.

During simulation of an IC design, traces of certain signals can be generated, thereby allowing defects in the design to be detected. The traces of these signals, i.e. the target set, are typically saved in a value change file. Unfortunately, this value change file can get very large, thereby causing capacity and performance problems. A technique is described in which a subset of signals that can regenerate the target set of signals is determined. Determining the subset of signals can include identifying state elements (e.g. edge-triggered devices) and corresponding signal dependencies of the IC design. Advantageously, only this subset of signals needs to be saved in the value change file, thereby significantly reducing its size. The target set of signals can be computed on demand after reading the value change file.

A system for delivering power over a network of devices connected through a serial link includes a first and second differential pairs of wires. Each differential pair of wires is double AC coupled by a HPF on one side and by another HPF on an opposite side. An LPF connects a portion of each differential pair of wires between the HPFs to a voltage source, and another LPF connects that portion of each differential pair to a load. The system further includes a third and fourth differential pairs of wires. All four differential pairs of wires are located within a single cable, such as a CAT6 cable. The first, second and third differential pair of wires are used for video links, and the fourth differential pair of wires are used for the bi-directional hybrid link. A power delivery circuit in each device includes a voltage source, a power relay switch, a signature resistor for detection, and a load detector.

A system for delivering USB data over a DiiVA network may include a USB host controller, at least one USB device, a first DiiVA device connected to the USB host controller through an upstream USB port, a second DiiVA device connected to the USB device through a downstream USB port; and a network configured to transfer data between the first DiiVA device and the second DiiVA device according to USB protocol through a DiiVA bi-directional hybrid link in the network. The network is responsive to the USB host controller to deliver contents for the USB protocol through at least one line state information packet and at least one USB data packet transmitted through the hybrid link between the upstream USB port and the downstream USB port.

A system may include a video link and a hybrid link that connects a transmitting device to the receiving device, and at least one intermediate hop between the transmitting device and the receiving device. The intermediate hop may be configured to relay video content from the video source to the video sink through the hybrid link using one or more data relay modes. The hybrid link may be configured to perform hybrid link control signaling (HLCS) to manage a physical layer of the hybrid link. The video link between the video source and the video sink may be configured to transmit a video stream the from video source to the video sink over one or more video lanes. A video link training may be implemented for the video link and the hybrid link.

A system and method for a catalog item virtual fulfillment center is described. The system determines whether an item from a search query on an online marketplace corresponds to a catalog item. The catalog item corresponds to an item sold at substantially the same price among different sellers of the online marketplace. A display of a menu of different shipping times and corresponding total costs is generated for the catalog item.
