  • Patent number: 11429848
    Abstract: In disclosed approaches of neural network processing, a host computer system copies an input data matrix from host memory to a shared memory for performing neural network operations of a first layer of a neural network by a neural network accelerator. The host instructs the neural network accelerator to perform neural network operations of each layer of the neural network beginning with the input data matrix. The neural network accelerator performs neural network operations of each layer in response to the instruction from the host. The host waits until the neural network accelerator signals completion of performing neural network operations of layer i before instructing the neural network accelerator to commence performing neural network operations of layer i+1, for i?1. The host instructs the neural network accelerator to use a results data matrix in the shared memory from layer i as an input data matrix for layer i+1 for i?1.

  • Patent number: 11422879
    Abstract: Embodiments herein describe error interceptors disposed along a bus that communicatively couples first and second circuits for redirecting in-band errors. That is, the error interceptors can block (or mask) in-band errors so they are not forwarded along the bus. Further, the error interceptors can redirect those errors such that they are converted into out-of-band errors. Moreover, the user can select which error interceptors to activate (e.g., block and redirect the errors) and which to deactivate (e.g., permit the in-band errors to pass). In this manner, the user can control which circuits receive in-band errors and which do not based on whether those circuits can handle the in-band errors.

  • Patent number: 11422781
    Abstract: Disclosed approaches for generating vector codes include inputting tensor processing statements. Each statement specifies an output variable, an initial variable, and multiply-and-accumulate (MAC) operations, and each MAC operation references the output variable, elements of a first tensor, and one or more elements of a second tensor. The MAC operations are organized into groups, and the MAC operations in each group reference the same output variable and have overlapping references to elements of the first tensor. For each group of MAC operations, at least one instruction is generated to load elements of the first tensor into a first register and at least one instruction is generated to load one or more elements of the second tensor into a second register. For each group of MAC operations, instructions are generated to select for each MAC operation in the group for input to an array of MAC circuits, elements from the first register and one or more elements from the second register.

  • Patent number: 11423303
    Abstract: Apparatus and associated methods relate to providing a machine learning methodology that uses the machine learning's own failure experiences to optimize future solution search and provide self-guided information (e.g., the dependency and independency among various adaptation behavior) to predict a receiver's equalization adaptations. In an illustrative example, a method may include performing a first training on a first neural network model and determining whether all of the equalization parameters are tracked. If not all of the equalization parameters are tracked under the first training, then, a second training on a cascaded model may be performed. The cascaded model may include the first neural network model, and training data of the second training may include successful learning experiences and data of the first neural network model. The prediction accuracy of the trained model may be advantageously kept while having a low demand for training data.

  • Publication number: 20220261523
    Abstract: Disclosed methods and systems involve, prior to mapping logic of the module to a target integrated circuit (IC) technology, estimating total delay of a module of a circuit design and determining whether or not the module is timing critical based on the total delay of the module and a timing constraint. Also prior to mapping, the module is restructured for timing optimization in response to determining that the module is timing critical. In response to determining that the module is not timing critical, and prior to mapping, the module is restructured for area optimization. The elements of the module are then mapped to the circuit elements of the target IC technology, followed by place-and-route and generating implementation data for making an IC that implements the circuit design.

  • Patent number: 11403068
    Abstract: Apparatus and associated methods relate to determining a natural exponent from a digital word input by splitting the digital word, and retrieving a precalculated and predetermined value from a data store at an address defined by the first word. In an illustrative example, the retrieved value may be a hyperbolic sum. The hyperbolic sum may be multiplied by the second word. The hyperbolic sum may be scaled, and summed with the multiplication result to generate a scaled exponential value. The scaled exponential value may be scaled to produce an exponential value representing eX. In various examples, the digital word input may be in a fixed point or a floating point format, or converted therebetween. In various embodiments, the data store may be a lookup table. Various examples may provide a compact and versatile architecture for determining a natural exponent with minimized hardware resources.
