Abstract: A display panel and a display device; the display panel includes a plurality of bonding pins. At least one bonding pin includes a first bonding electrode disposed on a side of an insulating layer group away from a base substrate, the insulating layer group having a first concave portion, the first bonding electrode having a second concave portion, an orthographic projection of the second concave portion on the base substrate being located within an orthographic projection of the first concave portion on the base substrate. The first bonding electrode includes at least a first conductor layer and a second conductor layer, and the at least one bonding pin further includes a filling portion disposed on a side of the second concave portion away from the base substrate, which is at least partially within the second concave portion.

Abstract: A dynamic-tile neural network accelerator allows for the number and size of computational tiles to be re-configured. Each sub-array of computational cells has edge cells on the left-most column that have an added vector mux that feeds the cell output back to an adder-comparator to allow Rectified Linear Unit (ReLU) and pooling operations that combine outputs shifted in from other cells. The edge cells drive external output registers and receive external weights. The weights and outputs are shifted in opposite directions horizontally between cells while control and input data are shifted in a same direction vertically between cells. A column of row data selectors is inserted between sub-arrays to bypass weights and output data around sub-arrays, while a row of column data selectors are inserted between sub-arrays to bypass control and input data. Larger tiles are configured by passing data directly through these selectors without bypassing.

Abstract: A device, method and system for controlling provisioning of a mobile device is provided. An example devices determines, upon power-up, a status of a provisioning flag. The example device, in response to the provisioning flag comprising a first state associated with an out-of-box update mode, implements a first provisioning stage associated with a first communication system according to the out-of-box update mode. The example device, in response to the provisioning flag comprising a second state associated with a post-deployment update mode, implements the first provisioning stage associated with the first communication system according to the post-deployment update mode different from the out-of-box update mode. The example device implements a second provisioning stage for one or more of the second communication system and an operating system implemented at the mobile device.

Abstract: A neural network accelerator reads encoded weights from memory. All 1 bits in a weight except the first three are discarded. The first three leading 1 bits in the weight are encoded as three bit-shift values to form the encoded weight. The three bit-shift values are applied to a bit shifter to shift a node input to obtain three shifted inputs that are accumulated to generate the node output. Node complexity is reduced since only 3 shifts are performed rather than up to 15 shifts for a 16-bit weight. The bit shifter and accumulator for a node can be implemented by Look-Up Tables (LUTs) without requiring a Multiply-Accumulate (MAC) cell in a Field-Programmable Gate Array (FPGA). Quantization bias is reduced using a histogram analyzer that determines a weighted average for each interval between quantized weights. The third bit-shift value is incremented for weights in the interval above the weighted average.

Abstract: A hybrid-resolution panoramic VR generator places High-Resolution (HR) patches from a ring of HR cameras onto a 360-degree Low-Resolution (LR) image from a LR camera pointing upward from the ring into a panoramic mirror that captures the combined field of view of all the multiple HR cameras, but at a lower resolution. Ghosting artifacts caused by parallax errors between adjacent HR cameras are eliminated because object placement is determined by the 360-degree LR image. Each HR image is homographicly projected into 3 projections by grouping objects of different depths to obtain homographic matrixes. The 360-degree LR image is upscaled to HR and a query patch is searched in search windows in the three projections for up to two adjacent HR images. Best-matching patches are weighted by similarity with the query patch and blended to generate a reconstructed patch placed at the query patch location in a reconstructed HR panorama image.

Abstract: A frame-rate converter reduces halo artifacts along edges of moving objects. Halo artifacts occur on interpolated frames where a moving object covers and uncovers pixels along its edges. Motion estimation among three original frames produces hybrid direction motion vectors that are bi-directional for background and objects, but are unidirectional for covered and uncovered regions, since motion vectors with large matching errors are deleted. Covered regions in the interpolated frame are detected as intersecting only a forward but no backward hybrid motion vector. Bi-directional motion estimation from the hybrid motion vectors of two original frames produces refined motion vectors for the interpolated frame. Refined motion vectors in the covered regions are deleted and replaced with hybrid motion vectors from the original frames. Hybrid motion vectors from the original frames are assigned to the critical covered regions rather than using interpolated vectors in the covered regions, reducing halo artifacts.
