Abstract: Modern FPGAs operate at a core voltage around 1V and therefore even small voltage fluctuations can lead to timing violations and logic errors. The Power Delivery Network (PDN) between a power supply and the FPGA core must be carefully designed to achieve a low output impedance over a broad range of frequencies. The present disclosure describes two techniques for characterization of the PDN: 1) to extract the DC resistance in the power delivery path, and 2) to identify the high impedance frequency band(s) in the PDN. An embedded impedance extraction tool is synthesized within the FPGA load, in coordination with a mixed-signal current-mode dc-dc converter. A self-calibrated Carry-Chain based ADC (CC-ADC) is used for high-speed sampling of the core voltage. By modifying the PDN based on the extracted results, the voltage operating range and reliability of a crossbar application may be greatly extended.

Abstract: A deep neural network(s) (DNN) may be used to detect objects from sensor data of a three dimensional (3D) environment. For example, a multi-view perception DNN may include multiple constituent DNNs or stages chained together that sequentially process different views of the 3D environment. An example DNN may include a first stage that performs class segmentation in a first view (e.g., perspective view) and a second stage that performs class segmentation and/or regresses instance geometry in a second view (e.g., top-down). The DNN outputs may be processed to generate 2D and/or 3D bounding boxes and class labels for detected objects in the 3D environment. As such, the techniques described herein may be used to detect and classify animate objects and/or parts of an environment, and these detections and classifications may be provided to an autonomous vehicle drive stack to enable safe planning and control of the autonomous vehicle.

Abstract: Methods and systems for updating the weights of a set of convolution kernels of a convolutional layer of a neural network are described. A set of convolution kernels having attention-infused weights is generated by using an attention mechanism based on characteristics of the weights. For example, a set of location-based attention multipliers is applied to weights in the set of convolution kernels, a magnitude-based attention function is applied to the weights in the set of convolution kernels, or both. An output activation map is generated using the set of convolution kernels with attention-infused weights. A loss for the neural network is computed, and the gradient is back propagated to update the attention-infused weights of the convolution kernels.
