A method of determining the center of loading of a rolling element includes providing a rolling element body and at least three load sensors. The sensors are each positioned within a bore of the rolling element body at a separate distance from a reference position. Load measurements are taken with each one of the sensors at various positions about the circumference of the bearing and the center of loading is calculated at each one of the positions to determine the variation in axial loading about the bearing circumference.

An DNN accelerator can perform fixed-point emulation of floating-point computation. In a multiplication operation on two floating-point matrices, the DNN accelerator determines an extreme exponent for a row in the first floating-point matrix and determines another extreme exponent for a column in the second floating-point matrix. The row and column can be converted to fixed-point vectors based on the extreme exponents. The two fixed-point vectors are fed into a PE array in the DNN accelerator. The PE array performs a multiplication operation on the two fixed-point vectors and generates a fixed-point inner product. The fixed-point inner product can be converted back to a floating-point inner product based on the extreme exponents. The floating-point inner product is an element in the matrix resulted from the multiplication operation on the two floating-point matrices. The matrix can be accumulated with another matrix resulted from a fixed-point emulation of a floating-point matrix multiplication.

Embodiments detailed herein relate to matrix operations. In particular, the loading of a matrix (tile) from memory. For example, support for a loading instruction is described in the form of decode circuitry to decode an instruction having fields for an opcode, a destination matrix operand identifier, and source memory information, and execution circuitry to execute the decoded instruction to load groups of strided data elements from memory into configured rows of the identified destination matrix operand to memory.

The present disclosure relates to matrix computing methods, chips, devices, and systems. One example method includes obtaining a computing instruction. The to-be-computed matrix is disassembled to obtain a plurality of disassembled matrices. Precision of a floating point number in the disassembled matrix is lower than precision of a floating point number in the to-be-computed matrix. Computing processing is performed on the plurality of disassembled matrices based on the matrix computing type.

Systems, apparatuses, and methods related to acceleration circuitry are described. The acceleration circuitry may be deployed in a memory device and can include a memory resource and/or logic circuitry. The acceleration circuitry can perform operations on data to convert the data between one or more numeric formats, such as floating-point and/or universal number (e.g., posit) formats. The acceleration circuitry can perform arithmetic and/or logical operations on the data after the data has been converted to a particular format. For instance, the memory resource can receive data comprising a bit string having a first format that provides a first level of precision. The logic circuitry can receive the data from the memory resource and convert the bit string to a second format that provides a second level of precision that is different from the first level of precision.
