Methods and apparatus of encoding/decoding point cloud geometry may use data sensed by at least one sensor associated with a sensor index. The point cloud geometry data is represented by ordered coarse points occupying some discrete positions of a set of discrete positions of a two-dimensional space, each occupied coarse point is associated with a radius based on a distance of the point of the point cloud from a referential. The encoding/decoding method comprises encoding/decoding a data representative of a predicting radius, and encoding, into the bitstream, a residual radius between a radius associated with an occupied coarse point and the predicting radius.

An encoder for encoding input data to generate corresponding encoded data is provided. The encoder identifies substantial reoccurrences of data blocks and/or data packets within at least a portion of the input data. The encoder then identifies, in respect of individual elements, where elements are unchanged and/or changed within the substantially reoccurring data blocks and/or data packets. Subsequently, the encoder encodes unchanged elements in the encoded data by employing at least one corresponding symbol, or at least one corresponding bit, for example a single bit, indicating an absence of change in the unchanged elements relative to corresponding elements in a reference data block and/or data packet. Moreover, the encoder encodes changed elements in the encoded data.

A system and method for low-power digital signal processing, for example, comprising adjusting a digital representation of an input signal.

A system, method and computer program product for encoding an input string of binary characters representing alphanumeric characters. A system includes: a character writing engine for writing a binary character to an empty cell of a multi-dimensional shape beginning with a starting empty cell; a next cell determination engine for determining a next empty cell by traversing neighboring cells in the multi-dimensional shape until an empty cell is located; a loop facilitator for looping back to the character writing engine and the next cell determining engine until no more data characters or a next empty cell is not determined; and a serialization engine for serializing the cells into a one dimensional binary string of characters representing an encoded string of alphanumeric characters.

A recovery mechanism for robust header compression (ROHC) is disclosed for wireless communication systems. The ROHC recovery mechanism may allow a receiver and/or transmitter in the wireless systems to establish or reestablish a context of a packet transmission session when an initialization and refresh message is lost. In the ROHC recovery mechanism, upon receiving a compressed packet that is not associated with a context, a receiver sends a message to a transmitter suggesting the transmitter to transition to another mode. Upon receiving a subsequent packet transmission that is not associated with a context, the receiver sends another message indicating that a context has not been established or has been lost. The transmitter may then send the receiver necessary information to establish a context for the packet transmission session.

Energy aware data compression is disclosed. A storage array may receive data from a client to be compressed. The storage array may request information from a compression awareness engine that is configured to estimate compression times in the context of energy source and energy cost. The storage array makes a decision to compress the data based on the estimates or response received from the compression awareness engine. The data is then compressed and stored in the storage array.

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.
