  • Auto-blow memory repair
    Patent number: 9490033
    Abstract: In an example embodiment, a method may include collecting, at a controller within an integrated circuit, defect information indicative of defects identified during a built-in self-test (BIST) operation performed on plural memories embedded within the integrated circuit. Fuses within the integrated circuit may be blown based on the defect information collected automatically and without software intervention. The fuses blown may be used to inform a built-in self-repair (BISR) operation performed on the plural memories.

  • Method and apparatus for power gating hardware components in a chip device
    Patent number: 9483100
    Abstract: According to at least one example embodiment, a semiconductor device is configured to gate power supply to a hardware component through a transistor coupled to the hardware component. The transistor is operated by a controller in a manner to limit electric current dissipated to the hardware component during a transition period. The controller is configured to gradually turn on, or off, the hardware component during a transition period by controlling at least one input signal to the transistor. Gradual turning on, or off, of the hardware component reduces electric current leakage through the hardware component and diminishes any potential disturbance to a ground reference coupled to the hardware component.

  • CONTENT SEARCH MECHANISM USING FINITE AUTOMATA
    Publication number: 20160232210
    Abstract: An improved content search mechanism uses a graph that includes intelligent nodes avoids the overhead of post processing and improves the overall performance of a content processing application. An intelligent node is similar to a node in a DFA graph but includes a command. The command in the intelligent node allows additional state for the node to be generated and checked. This additional state allows the content search mechanism to traverse the same node with two different interpretations. By generating state for the node, the graph of nodes does not become exponential. It also allows a user function to be called upon reaching a node, which can perform any desired user tasks, including modifying the input data or position.

  • IMPLEMENTING 128-BIT SIMD OPERATIONS ON A 64-BIT DATAPATH
    Publication number: 20160140079
    Abstract: A method of implementing a processor architecture and corresponding system includes operands of a first size and a datapath of a second size. The second size is different from the first size. Given a first array of registers and a second array of registers, each register of the first and second arrays being of the second size, selecting a first register and corresponding second register from the first array and the second array, respectively, to perform operations of the first size. This allows a user, who is interfacing with the hardware processor through software, to provide data of the datapath bit-width instead of the register bit-width. Advantageously, the user is agnostic to the size of the registers.

  • Content search mechanism that uses a deterministic finite automata (DFA) graph, a DFA state machine, and a walker process
    Patent number: 9336328

    Publication number: 20150379470
    Abstract: A method of automatically re-organizing structured data in a reporting system based on screen size calculated an initial layout for data containers in a report, checks to see if any of the data containers are obscured by the right display edge, and re-arranges the data containers so that no containers are obscured. A similar process is performed on any data grids with obscured columns. Columns are removed according to importance to maintain context. Elements in a removed column are added below respective associated rows.

  • Dynamically Adjusting Supply Voltage Based On Monitored Chip Temperature
    Publication number: 20150091638
    Abstract: In an embodiment, a method includes monitoring a temperature of a semiconductor chip and adjusting a supply voltage to the semiconductor chip based on the monitored temperature. The temperature may be monitored by a temperature sensor located on-chip or off-chip. Adjusting the supply voltage includes increasing the supply voltage as a function of the monitored temperature decreasing. The increase to the supply voltage occurs only if the monitored temperature is below a threshold temperature. The supply voltage adjustment is determined by a linear relationship having a negative slope with temperature.

  • Method and Apparatus for Managing Global Chip Power on a Multicore System on Chip
    Publication number: 20150089251
    Abstract: According to at least one example embodiment, a method and corresponding apparatus for controlling power in a multi-core processor chip include: accumulating, at a controller within the multi-core processor chip, one or more power estimates associated with multiple core processors within the multi-core processor chip. A global power threshold is determined based on a cumulative power estimate, the cumulative power estimate being determined based at least in part on the one or more power estimates accumulated. The controller causes power consumption at each of the core processors to be controlled based on the determined global power threshold. The controller may directly control power consumption at the core processors or may command the core processors to do so.
