  • Patent number: 11600894
    Abstract: Provided is a rapid over-the-air (OTA) production line test platform, including a device under test (DUT), an antenna array and two reflecting plates. The DUT has a beamforming function. The antenna array is arranged opposite to the DUT, and emits beams with beamforming. Two reflecting plates are disposed opposite to each other, and are arranged between the DUT and the antenna array. The beam OTA test of the DUT is carried out by propagation of the beams between the antenna array, the DUT and the two reflecting plates. Accordingly, the test time can be greatly shortened and the cost of test can be effectively reduced. In addition to the above-mentioned rapid OTA production line test platform, platforms for performing the OTA production line test by using horn antenna arrays together with bending waveguides and using a 3D elliptic curve are also provided.

  • Publication number: 20230062503
    Abstract: Hierarchical structured sparse parameter pruning and processing improves runtime performance and energy efficiency of neural networks. In contrast with conventional (non-structured) pruning which allows for any distribution of the non-zero values within a matrix that achieves the desired sparsity degree (e.g., 50%) and is consequently difficult to accelerate, structured hierarchical sparsity requires each multi-element unit at the coarsest granularity of the hierarchy to be pruned to the desired sparsity degree. The global desired sparsity degree is a function of the per-level sparsity degrees. Distribution of non-zero values within each multi-element unit is constrained according to the per-level sparsity degree at the particular level of the hierarchy. Each level of the hierarchy may be associated with a hardware (e.g., logic or circuit) structure that can be enabled or disabled according to the per-level sparsity.

  • Publication number: 20220083314
    Abstract: Accelerators are generally utilized to provide high performance and energy efficiency for tensor algorithms. Currently, an accelerator will be specifically designed around the fundamental properties of the tensor algorithm and shape it supports, and thus will exhibit sub-optimal performance when used for other tensor algorithms and shapes. The present disclosure provides a flexible accelerator for tensor workloads. The flexible accelerator can be a flexible tensor accelerator or a FPGA having a dynamically configurable inter-PE network supporting different tensor shapes and different tensor algorithms including at least a GEMM algorithm, a 2D CNN algorithm, and a 3D CNN algorithm, and/or having a flexible DPU in which a dot product length of its dot product sub-units is configurable based on a target compute throughput that is less than or equal to a maximum throughput of the flexible DPU.

  • Patent number: 10956227
    Abstract: Examples provide two-tiered scheduling within a cluster. A coarse-grained analysis is performed on a candidate set of hosts to select a host for a virtual computing instance based on optimization of at least one resource. A host is selected based on the analysis results. The identified virtual computing instance is placed on the selected host. A fine-grained analysis is performed on a set of communication graphs for a plurality of virtual computing instances to generate a set of penalty scores. A set of communicating virtual computing instances are selected based on the set of penalty scores. A first virtual computing instance from a first host is relocated to a second host to minimize a distance between the first virtual computing instance and a second virtual computing instance. Relocating the first virtual computing instance reduces at least one penalty score for the set of communicating virtual computing instances.

  • Publication number: 20180349017
    Abstract: The present disclosure is related to a system and a system for displaying handwriting synchronously, and a handwriting device thereto. The handwriting device adopts a bistable display panel and includes a sensor circuitry that is used to record the handwriting contents over the panel. The sensor circuitry through the handwriting renders handwriting positions and pressure values. These sensed data is transmitted to a computer device instantly when the data of positions and pressure values are generated by the handwriting device. In the computer device, the handwriting can be synchronously displayed through a transformation from the received data to displaying positions and pressure values. Finally, in the computer device, a document recording the handwriting track over time is created. The document can be a picture, a video, or even a document with audio.
