  • Publication number: 20230342110
    Abstract: A variable width barrel shifter. The variable width barrel shifter includes a first barrel shifter configured to receive a data vector of width M as input. The variable width barrel shifter further includes a second barrel shifter configured to receive the data vector of width M as input. The variable width barrel shifter includes an element-wise multiplexer coupled to the first and second barrel shifters. The element-wise multiplexer is configured to provide a shifted output of the data vector of width M by including a first portion of output from the second barrel shifter and a second portion of output from the first barrel shifter.

  • Patent number: 11552704
    Abstract: Synchronizing a pulse position modulation (PPM) signal. A method includes performing a first synchronization operation by receiving a first series of symbols. The symbols in the first series are transmitted with a pulse in a known slot, such that the symbols comprise pulses that are substantially equally spaced in time from adjacent symbols. The first synchronization operation includes identifying when each pulse is received for each of the symbols and using information identifying when each pulse is received for each of the symbols in the first series of symbols to identify symbol and slot boundaries for the pulse position modulation signal. The method further includes performing a second synchronization operation by receiving a second series of symbols transmitted in a known pattern, and identifying the known pattern in the received second series of symbols to identify a frame boundary.

  • Patent number: 9341677
    Abstract: A data alignment method is provided by iteratively increasing the delay of each data input line of a system component until a test signal transmitted on each data input line is received at the system component at substantially a predetermined time.

  • Patent number: 8724690
    Abstract: The present invention is directed to a decision feedback equalizer that implements a multipath delay calculator to determine the delay between a line-of-sight component of a received data signal and a reflection of the line-of-sight component. The determined delay is used to control when decisions are used within the decision feedback equalizer so that the appropriate decisions are delayed until the reflection is received. In this way, the reflection can be substantially removed from the data signal using decisions that were generated when the line-of-sight component was received. Because the correction window is limited to the time when the reflection is received, the number of taps required to perform equalization is greatly reduced resulting in a decision feedback equalizer with less circuitry or logic.
