    Abstract: A transformer compute apparatus and method of operation therefor. The apparatus receives matrix inputs in a first format and generates projection tokens from these inputs. Among others, the apparatus includes a first cache device configured for processing first projection tokens and a second cache device configured for processing second projection tokens. The first cache device stores the first projection tokens in a first cache region and stores these tokens converted to a second format in a second cache region. The second cache device stores the second projection tokens converted to the second format in a first cache region and stores the converted second projection tokens after being transposed. Then, a compute device performs various matrix computations with the converted first projection tokens and transposed second projection tokens. Re-processing data and expensive padding and de-padding operations for transposed storage and byte alignment can be avoided using this caching process.

  • Patent number: 12112263
    Abstract: In an example embodiment, a model is trained to specifically identify reversal points in data and then to rank these reversal points in order of importance. A reversal point shall be defined as a point in which a particular metric, specifically a first order derivative, crosses over from positive to negative or vice-versa. Users are more likely to be interested in abnormal and significant changes in data, and thus the machine-learned model is trained to evaluate a reversal point based on two dimensions: abnormality and significance.

According to the temperature compensation circuit of the disclosure, the reference arrays have the same structure as the computing-in-memory array. The insertion density of the reference arrays is related to the temperature field where the computing-in-memory arrays are located.

The syntax elements are of various types that correspond to transform coefficients of a transform block in a coded picture. Context modeling is performed to determine a context model for each bin of the syntax elements. In a given frequency region of the transform block, for one type of the syntax elements, a group of the transform coefficients having different template magnitudes within a predetermined range share a same context model, or one of the transform coefficients uses the same context model for possible different template magnitudes of the one of the transform coefficients. The possible different template magnitudes are within the predetermined range. The coded bits are decoded based on the context models determined for each bin of the syntax elements to determine the bins of the syntax elements.

  • Patent number: 11496124
    Abstract: A numerically-controlled oscillator (NCO) includes a phase accumulator (PA) which has a first input adapted to receive a phase increment, a second input adapted to receive a clock signal, and a third input adapted to receive a reset signal. The PA provides an instantaneous phase at an output. The NCO includes a dithered splitter which has an input coupled to receive the instantaneous phase. The dithered splitter dithers the instantaneous phase using a pseudo-random binary sequence (PRBS) and provides a dithered course phase and a dithered fine phase. The NCO includes a polynomial approximation unit which has a first input coupled to receive the dithered course phase and a second input coupled to receive the dithered fine phase. The polynomial approximation unit provides a sequence of numbers representing a discrete sinusoidal signal.

  • Patent number: 11483575
    Abstract: A video coder that constrains the total number of regular bins used for entropy coding syntax elements of a current block is provided. The video coder entropy encodes or decodes the syntax elements selectively as either regular bins using context modeling or as bypass bins without context modeling. A constraint is specified to limit a total number of regular bins used for entropy coding the syntax elements of the current block. There may be no constraint limiting a number of regular bins specific to an individual syntax element of the current block.
