    Abstract: A method and an apparatus for slicing a multilevel analog signal using a two-level slicer having one threshold level to generate an analog error signal. The method may be performed by delaying a received multilevel analog signal in a plurality of serial analog stages (n), further delaying a multilevel analog signal tapped from stage n, combining the further delayed signal from stage n with an analog error signal e(t) to provide an analog weighting function Wn, wherein the combining of the delayed signal from stage n with Wn results in a plurality of signals XnWn, summing the plurality of signals XnWn, slicing a multilevel analog signal resulting from the summing of the plurality of signals XnWn using one threshold level to generate the analog error signal e(t), and combining the delayed signal from stage n with Wn.

    Abstract: Present embodiments describe a CAM device having a segmented CAM array. Each segment of the CAM array, or cell blocks, includes one or more rows of CAM cells. One or more of the cell blocks in the CAM array are selectively enabled during a search operation based on a detected matching condition of another cell block. By selectively enabling cell blocks during search operations only when needed, energy consumption is reduced. Selectively enabling a cell block includes selectively pre-charging match lines to the cell block, selectively enabling word lines to the cell block, and selectively enabling comparand line to the cell block. In accordance with certain embodiments, the CAM device is configurable to perform search operations in a pipelined manner. Accordingly, the CAM device is capable of performing multiple search operations simultaneously.

    Abstract: Approaches for an improved encoding scheme that allows a CAM device to selectively store, within each cell of a row of the CAM device, either a single bit of a binary value or two bits of an encoded data word encoded from the binary value. By storing two bits of the encoded data word in each CAM cell, data may be stored more efficiently and CAM systems may consume less power as compared to traditional binary CAMS when performing certain types of operations, such as exact matching and longest prefix matching. Encoded data words may be, but need not be, balanced data words which have equal number of logic high and logic low values.

    Abstract: A method and apparatus for a multiple lane transmission system that provides both a low latency mode of operation, while at the same time, provides reduced lane-lane skew. The overall transmission system operates as a mesochronous system, whereby each clock domain of the transmission system is synchronized to the leaf nodes of a global clock tree. A phase aligner is then used to align the phase of both the bit and byte clocks of each transmission lane to the clock signal generated at the leaf nodes of the global clock tree.
