  • Patent number: 7714354
    Abstract: A method is provided for electroforming metal integrated circuit structures. The method comprises: forming an opening such as a via or line through an interlevel insulator, exposing a substrate surface; forming a base layer overlying the interlevel insulator and substrate surface; forming a strike layer overlying the base layer; forming a top layer overlying the strike layer; selectively etching to remove the top layer overlying the substrate surface, exposing a strike layer surface; and, electroforming a metal structure overlying the strike layer surface. The electroformed metal structure is deposited using an electroplating or electroless deposition process. Typically, the metal is Cu, Au, Ir, Ru, Rh, Pd, Os, Pt, or Ag.

  • Patent number: 7707398
    Abstract: A system and method are provided for updating a speculative global history prediction record in a microprocessor system using pipelined instruction processing. The method accepts microprocessor instructions with consecutive operations, including a conditional branch operation with an associated first branch address. A speculative global history record (SGHR) of conditional branch resolutions and predictions is accessed and hashed with the first branch address, creating a first hash result. The first hash result is used to index a branch history table (BHT) of previous first branch resolutions. As a result, a first branch prediction is made, and the SGHR is updated with the first branch prediction. A non-speculative global history record (NSGHR) of branch resolutions is updated with the resolution of the first branch operation, and if the first branch prediction is incorrect, the SGHR is corrected using the NSGHR.

  • Patent number: 7698077
    Abstract: An electronic signal level detection system and method are provided. The method receives an analog input signal having a variable voltage and compares the input signal voltage to a threshold. A detection signal is generated for input signal voltages exceeding the threshold in a periodic first time frame. In a second periodic time frame (following the first time frame), a count is updated in response to the generated detection signals. The count is used to create a metric representative of the difference between the input signal voltage and the threshold. The count is incremented in response to the generating a detection signal (“1”) in the first time frame, and decremented in response to not generating a detection signal (“0”) in the first time frame.

  • Patent number: 7682948
    Abstract: A system and method are provided for crystallizing a semiconductor film using a digital light valve. The method comprises: enabling pixel elements from an array of selectable pixel elements; in response to enabling the pixel elements, gating a light; sequentially exposing adjacent areas of a semiconductor film, such as Si, to the gated light; annealing the light-exposed areas of semiconductor film; and, in response to the annealing, laterally growing crystal grains in the semiconductor film. For example, the method may sequentially expose adjacent areas of semiconductor film to gated light in a first direction; and, simultaneously exposing adjacent areas of semiconductor film to gated light in a second direction, different than the first direction. For example, the second direction may be perpendicular to the first direction. As a result, crystal grains can be laterally grown simultaneously in the first and second directions.

  • Patent number: 7649965
    Abstract: A system and method are provided for maximum likelihood estimation in a channel receiving data with inter-symbol interference (ISI). The method receives a serial stream of digital information bits. Decisions are made concerning the received information bit values, which the method accepts as processed information, with soft decisions (SDs) and corresponding initial hard decisions (HDs). The method then identifies a sequence of processed information in a correction matrix, and uses the correction matrix to cross-reference the sequence to a HD look-up value. In response to accessing the HD look-up value, a modified HD is created. The modified HD is decoded, for example, by using forward error correction (FEC), creating a decoded HD. The method compares the decoded HD to the initial HD, and updates the correction matrix HD look-up value in response to the comparison.

Initially, Polling Request messages are sent to the PHY device, and Polling Result messages received from the PHY device, as is conventional. In response to analyzing the Polling messages, a transmission pattern is determined, which includes the amount of information to transmit and a period between transmissions.
