  • Publication number: 20230376765
    Abstract: Deep learning operations (e.g., transposed convolution, resized convolution, dilated convolution, etc.) may be performed with sparsity maps and storage pointers. A deep learning operation has a tensor, which can be used to generate an upsampled tensor by adding new data elements (e.g., zeros) into the tensor. One or more sparsity maps may be generated based on one or more parameters of the first deep learning operation. The sparsity map may include elements indicating whether a data element in the upsampled tensor is a data element in the tensor or is a new data element. One or more storage pointers may be generated. A storage pointer may indicate a location (e.g., a memory address) where one or more data elements of the tensor are stored in a memory. An output of the deep learning operation may be performed using data elements in the tensor, the sparsity maps, and the storage pointers.

  • Publication number: 20230017662
    Abstract: An DNN accelerator includes a DMA engine that can rearrange weight data layout. The DMA engine may read a weight tensor from a memory (e.g., DRAM). The weight tensor includes weights arranged in a 3D matrix. The DMA engine may partition the weight tensor into a plurality of virtual banks based on a structure of a PE array, e.g., based on the number of activated PE columns in the PE array. Then the DMA engine may partition a virtual bank into a plurality of virtual sub-banks. The DMA engine may also identify data blocks from different ones of the plurality of virtual sub-banks. A data block may include a plurality of input channels and may have a predetermined spatial size and storage size. The DMA engine form a linear data structure by interleaving the data blocks. The DMA engine can write the linear data structure into another memory (e.g., SRAM).

  • Patent number: 7801442
    Abstract: Embodiments introduce redundant optical channels to significantly extend the lifetime of parallel optical transceivers. A plurality of transmitters, N, transmit on a plurality of optical channels, where N is an integer number of optical channels greater than 1. One or more redundant channels, M, are also provided. N+M multiple input shift registers provide multiple paths for signals from each of the transmitters to connect to N+M laser diodes. In the event up to M of the N+M laser diodes fail, the multiple input shift registers connect the N transmitters to functioning ones of the N+M laser diodes thus extending the life of the device. A corresponding scheme is also described for the receiver side.

  • Publication number: 20070196112
    Abstract: According to embodiments of the present invention, an optical receiver detects an optical signal, determines the signal strength, and is placed in a power save mode if the optical signal strength falls below a predetermined level. A microcontroller may instruct a transimpedance amplifier integrated circuit (TIA IC) or other circuitry in the receiver to turn off one or more of its components during power save mode. If the optical signal strength rises above the predetermined level, the microcontroller may instruct the TIA IC to return to normal mode.

  • Patent number: 7195203
    Abstract: A simplified structure for a wing skin and wing box wherein the internal surface (2) of an aircraft wing skin panel (1) in the wing box includes a multiplicity of strips (3), each strip being associated with a stringer. The strips (3) have different gradients in the span-wise direction S, which is the direction in which the strips extend. The surface of each strip is, in the chord-wise direction C, parallel to the external surface (5). At a junction, at which a rib meets a stringer, the interior surface (2) has an area (4a) that is parallel to the exterior surface (5), such that the rib and stringer at that junction may be simply attached to the wing skin panel (1).
