  • Publication number: 20190229966
    Abstract: A hybrid multi-layer method for decomposing of a source signal to a plurality of decomposed signals that can be used to collectively represent the source signal or recover the source signal. An example embodiment is a method that includes multi-layer (or multi-stage) signal decomposition to generate constant envelope signals without impact on the original signal. In an example embodiment, the method includes signal decomposition to maintain constant envelope properties and limit bandwidth expansion from the signal decomposition. The method includes decomposing a source signal into two first-stage decomposed signals that each have a constant envelope amplitude value. The method further includes iteratively decomposing each of the constant envelope signals into further-stage decomposed signals based on a threshold amplitude value at each iteration. The further-stage decomposed signals have a constant envelope with an envelope amplitude value in dependence of the threshold amplitude value at each iteration.

  • Patent number: 10318297
    Abstract: A self-timed parallelized multi-core processor has an instruction decoder unit for receiving a program code instruction, determining an operating code and latency for the instruction, and assigning a loop index to the instruction. An instruction decomposer creates a primitive by decomposing the instruction, replacing the loop index with a core index, and broadcasting the primitive. Self-timed processing cores each having a unique core index compare the core index to their unique processing core index. The processing cores act on the primitive when their processing core index is within a threshold of the core index.

    Abstract: Methods and apparatuses relating to QR decomposition using a multiple execution unit processing system are provided. A method includes receiving input values at the processing system and generating a first set of values based on the input values, where at least some of the first values are computed in parallel. A second set of values are generated recursively based on values in the first set. A third set of values are generated based on values in the second set, where at least some of the values in the third set are computed in parallel. The recursive component may be simplified to consist of one or more low latency operations. The processing performance of operations relating to QR decomposition may therefore be improved by using the parallelism available in multiple execution unit systems.
