An image processing method is provided. Since in the present invention, the first quantization threshold obtained by the saturated mapping method and the second quantization threshold obtained by the unsaturated mapping method are weighted, it is equivalent to fusing two quantization threshold values. The obtained optimal quantization threshold can be applied to most activations, to more effectively retain the effective information of the activations and use in subsequent image processing, thereby improving the accuracy of inference computations of the quantified deep neural network on low-bit-width hardware platforms. An image processing device and apparatus have the same beneficial effects as the above image processing method.

Image processing method, device and apparatus

The present invention provides a method and apparatus for data caching. The method comprises: output matrixes are acquired one by one, a plurality of acquired output matrixes are written alternately into two queue sets of a first cache unit according to a sequence in which the output matrixes are acquired, and the output matrixes stored line by line in a first cache unit are written into a second cache unit one by one, according to the sequence in which the output matrixes are written into the second cache unit, valid data of each output matrix of the second cache unit is determined one by one according to preset parameters, and the valid data of each output matrix is written into a third cache unit, and the valid data of the output matrixes stored in the third cache unit are configured to be sequentially written into a memory according to a sequence in which the valid data are written into the third cache unit. In the present solution, the output matrixes are cached by using cache units with the writing speed matching with the computing speed of a processor, and the output matrixes are completely written into a memory one by one according to a sequence of generation time. Therefore, the present invention may solve the problem that the computing speed of the processor does not match with the writing speed of the memory.

Method and apparatus for data caching

A data storage method, apparatus, and device, and a readable storage medium. The method includes: after a random access memory is powered on, obtaining target data to be stored in a fixed storage address of the random access memory; determining a target transmission mode from a bit value change transmission mode and a bit value fixed transmission mode, wherein the target transmission mode is different from a historical transmission mode determined after the random access memory is powered on last time; and transmitting the target data from and to the random access memory according to the target transmission mode. The method can prevent data from being stolen after power-down of the target data, and guarantees the data security.
