  • Patent number: 10997277
    Abstract: An integrated circuit device such as a neural network accelerator can be programmed to select a numerical value based on a multinomial distribution. In various examples, the integrated circuit device can include an execution engine that includes multiple separate execution units. The multiple execution units can operate in parallel on different streams of data. For example, to make a selection based on a multinomial distribution, the execution units can be configured to perform cumulative sums on sets of numerical values, where the numerical values represent probabilities. In this example, to then obtain cumulative sums across the sets of numerical values, the largest values from the sets can be accumulated, and then added, in parallel to the sets. The resulting cumulative sum across all the numerical values can then be used to randomly select a specific index, which can provide a particular numerical value as the selected value.

  • Publication number: 20210116915
    Abstract: In one embodiment, a set of parameters representing a first state of an autonomous driving vehicle (ADV) to be simulated and a set of control commands to be issued at a first point in time. In response, a localization predictive model is applied to the set of parameters to determine a first position (e.g., x, y) of the ADV. A localization correction model is applied to the set of parameters to determine a set of localization correction factors (e.g., ?x, ?y). The correction factors may represent the errors between the predicted position of the ADV by the localization predictive model and the ground truth measured by sensors of the vehicle. Based on the first position of the ADV and the correction factors, a second position of the ADV is determined as the simulated position of the ADV.

  • Publication number: 20210116916
    Abstract: A method of navigating an autonomous driving vehicle (ADV) includes determining a target function for an open space model based on one or more obstacles and map information within a proximity of the ADV, then iteratively performing first and second quadratic programming (QP) optimizations on the target function. Then, generating a second trajectory based on results of the first and second QP optimizations to control the ADV autonomously using the second trajectory. The first QP optimization is based on fixing a first set of variables of the target function. The second QP optimization is based on maximizing a sum of the distances from the ADV to each of the obstacles over a plurality of points of the first trajectory, and minimizing a difference between a target end-state of the ADV and a determined final state of the ADV using the first trajectory.

  • Publication number: 20210096823
    Abstract: Provided are integrated circuits and methods for transposing a tensor using processing element array operations. In some cases, it may be necessary to transpose elements of a tensor to perform a matrix operation. The tensor may be decomposed into blocks of data elements having dimensions consistent with the dimensions of a systolic array. An identity multiplication may be performed on each block of data elements loaded into a systolic array and the multiplication products summed in column partitions of a results buffer. The data elements in the column partitions of results buffer can then be mapped to row partitions of a buffer memory for further processing.

  • Patent number: 10929063
    Abstract: Systems and methods for assisted indirect memory addressing are provided. Some computing systems move data between levels of a hierarchical memory system. To accommodate data movement for computing systems that do not natively support indirect addressing between levels of the memory hierarchy, a direct memory access (DMA) engine is used to fetch data. The DMA engine executes a first set of memory instructions that modify a second set of memory instructions to fetch data stored at one level of the memory hierarchy from dynamically computed indirect addresses stored in memory locations at another level of the memory hierarchy.
