Abstract: To reduce direct memory access (DMA) overhead, a tensorized descriptor can be used to generate a series of memory descriptors to perform a series of DMA data transfers. The tensorized descriptor may include attributes such as a stride and a memory descriptor template, which can be used to generate the series of memory descriptors. Hence, instead of having to retrieve each of the memory descriptors to perform the series of DMA transfers, a single tensorized descriptor can be retrieved to perform a series of data transfers.

Abstract: Data received from an in-situ monitoring system includes, for each scan of a sensor, a plurality of measured signal values for a plurality of different locations on a layer. A thickness of a polishing pad is determined based on the data from the in-situ monitoring system. For each scan, a portion of the measured signal values are adjusted based on the thickness of the polishing pad. For each scan of the plurality of scans and each location of the plurality of different locations, a value is generated representing a thickness of the layer at the location. This includes processing the adjusted signal values using one or more processors configured by machine learning. A polishing endpoint is detected or a polishing parameter is modified based on the values representing the thicknesses at the plurality of different locations.

Abstract: The present invention discloses a method and a device for laser-assisted electrochemical composite deposition using a rifling-type hollow rotating electrode, which relate to the field of micro-composite processing in special processing technologies. A center of a laser beam is allowed to pass through a rifling-type hollow rotating electrode and focus onto a cathode substrate. When the rifling-type hollow rotating electrode is rotated at a constant speed, an electrodeposition solution rotates in the rifling-type hollow rotating electrode and generates a certain centripetal force to improve the precision and localization of deposition. During the process of the present invention, an internal rifling structure of the electrode is rotated at a high speed so that the deposition solution generates a centripetal force. The internal rifling structure and an external helical structure of the rifling-type hollow rotating electrode make the deposition solution move upward to form a “self-circulation” system.

The DMA engine may include a calculation circuit operable to perform a multiply-and-add calculation on a set of operands, and an operand selector circuit operable to select a source for each operand of the calculation circuit. The DMA engine may also include a control circuit operable to retrieve a meta-descriptor for performing a computation, configure the operand selector circuit based on the meta-descriptor, and use the calculation circuit to perform the computation based on the meta-descriptor to generate a computation result.

Abstract: To reduce the storage size of weight tensors and speed up loading of weight tensors from system memory, a compression technique can be employed to remove zero values from a weight tensor before storing the weight tensor in system memory. A sparsity threshold can be enforced to achieve a compression ratio target by forcing small weight values to zero during training. When the weight tensor is loaded from system memory, a direct memory access (DMA) engine with an in-line decompression unit can decompress the weight tensor on-the-fly. By performing the decompression in the DMA engine, expansion of the weight values back to the original weight tensor size can be carried out in parallel while other neural network computations are being performed by the processing unit.

Abstract: Disclosed are a device and a method for microelectrodeposition through a laser assisted flexible following tool electrode. Localization of electrodeposition and dimensional precision of members are enhanced by using the flexible following tool electrode to restrict a dispersion region of an electric field and a reaction region of electrodeposition, and a complex-shaped member can be deposited by controlling a motion path of the flexible following tool electrode. Since a laser has a high power density, introducing laser irradiation changes an electrode state in a radiated region, accelerates ion diffusion and electron transfer speeds, and increases a deposition rate, thus reducing defects such as pitting and cracking in a deposit, enhancing deposition quality, and achieving fabrication of a micro-part by a synergistic action of both electrochemical energy and laser energy.
