  • Patent number: 10599178
    Abstract: Some implementations disclosed herein provide techniques and arrangements for transferring data between asynchronous clock domains. A synchronization signal may be generated by a first of the clock domains, and data may be transferred between the domains in response to the synchronization signal. Clock cycles of the second of the clock domains may be monitored in comparison to the synchronization signal to report the number of second clock domain cycles occurring per occurrence of the synchronization signal. This information may be recorded by testing and validation equipment to facilitate error analyses.
    Type: Grant
    Filed: July 16, 2018
    Date of Patent: March 24, 2020

  • Patent number: 6362672
    Abstract: A method and apparatus for matching rise time and fall time in two differential signals. The apparatus includes a system that includes an scaled summer, a reference voltage generator, a comparator, and a storage device. The scaled summer receives two input signals and generates an instantaneous scaled sum of the two input signals. The reference voltage generator generating a reference voltage. The comparator compares the scaled summer output signal and the reference voltage and generates a comparison signal. The storage device stores the comparison signal. The stored comparison signal is usable to adjust one of the rise time and the fall time of both of the two input signals to match one of the fall time and the rise time of the two input signals.
