    Abstract: In a first method, a wireless device estimates a delay profile of a channel impulse response, CIR, for a channel between a network node and the wireless device, compresses the delay profile using a compression function, and transmits the compressed delay profile. The compression function includes a first function and a quantizer. The first function is configured to receive input data and reduce a dimension of the input data. In a second method, a network node receives a compressed delay profile of CIR for a channel between a network node and a wireless device, decompresses the compressed delay profile using a decompression function, and estimates a position of the wireless device based on at least the decompressed delay profile. The decompression function includes a first function which is configured to receive input data and provide output data in a higher dimensional space than the input data.

    Abstract: The present disclosure provides example operation accelerators and compression methods. One example operation accelerator includes a storage configured to store first input data, weight data, and a control instruction, and an operation circuit connected to the storage and configured to perform matrix multiplication on the first input data and the weight data, to obtain a computation result. The operation accelerator further includes a compression module configured to compress the computation result to obtain compressed data, as well as a controller connected to the storage and configured to obtain the control instruction from the storage, and when the control instruction includes instructions to compress the computation result, control the compression module to compress the computation result to obtain the compressed data. The operation accelerator further includes a direct memory access controller connected to the compression module and configured to store the compressed data in a memory outside the operation accelerator.

    Abstract: The embodiments relate to a method for encoding two or more tensors. The method comprises processing the two or more tensors having respective dimensions so that the dimensions of said two or more sensors have the same number (510); identifying which axis of each individual tensor is swappable to result in concatenable tensors around an axis of concatenation (520): reshaping the tensors so that the dimensions are modified based on the swapped axis (530): concatenating the tensors around the axis of concatenation to result in concatenated tensor (540): compressing the concatenated tensor (550); generating syntax structures for carrying concatenation and axis swapping information (560): and generating a bitstream by combining the syntax structures and the compressed concatenated tensor (570). The embodiments also relate to a method for decoding, and to apparatuses for implementing the methods.

    Abstract: A data processing method includes a computing device that obtains first data, and determines a deduplication rate of the first data and a working status of the computing device. When the working status of the computing device is a busy state, and when the deduplication rate of the first data is greater than or equal to a first preset value, deduplication on the first data is performed. When the deduplication rate of the first data is lower than the first preset value, deduplication is not performed on the first data, and the first data may be directly stored.

    Abstract: The present disclosure discloses example operation accelerators and compression methods. One example operation accelerator performs operations, including storing, in a first buffer, first input data. In a second buffer, weight data can be stored. A computation result is obtained by performing matrix multiplication on the first input data and the weight data by an operation circuit connected to the input buffer and the weight buffer. The computation result is compressed by a compression module to obtain compressed data. The compressed data can be stored into a memory outside the operation accelerator by a direct memory access controller (DMAC) connected to the compression module.
