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.

Abstract: Techniques are disclosed for debugging a neural network execution on a target processor. A reference processor may generate a plurality of first reference tensors for the neural network. The neural network may be repeatedly reduced to produce a plurality of lengths. For each of the lengths, a compiler converts the neural network into first machine instructions, the target processor executes the first machine instructions to generate a first device tensor, and the debugger program determines whether the first device tensor matches a first reference tensor. A shortest length is identified for which the first device tensor does not match the first reference tensor. Tensor output is enabled for a lower-level intermediate representation of the shortest neural network, and the neural network is converted into second machine instructions, which are executed by the target processor to generate a second device tensor.

Abstract: The present disclosure relates to a device and a method for removing a carbon from an oxygen sensor. The device may include an oxygen sensor installed in a gas exhaust line of a vehicle to measure an oxygen content in an exhaust gas, a valve for transferring a high-pressure air flow to the oxygen sensor, a valve actuator for driving the valve, and a controller for controlling the valve actuator to open the valve when an abnormality occurs in the oxygen sensor. When the abnormality has occurred in the oxygen sensor, the valve for transferring the high-pressure air flow is opened, and a temperature of zirconia provided in the oxygen sensor is raised to remove a carbon deposited on the oxygen sensor.
