Problems solved by technology

[0003] However, due to the wide application of fixed-point and sparsification, a large number of continuous zeros usually appear in the model data, occupying a large amount of bandwidth resources and affecting the overall processing efficiency of the neural network processor
In the processing process of the processor, coding technology is usually used to compress the redundant data, but the compressed data cannot directly participate in the operation

Embodiment approach

[0244] As an optional implementation manner, it specifically includes the following steps:

[0245] Step 7042a, acquire the data length of the character code.

[0246] Specifically, the decoding device in the processor acquires the data length of one of the multiple character codes with the same value.

[0247] Step 7044b, compare the data length of the character code with the data bit width.

[0248] Specifically, the decoding device in the processor compares the data length of the character code acquired in step 7042 with the set data bit width, and judges whether the data length of the character code acquired in step 7042 is equal to the set data bit width Is it equal.

[0249] Step 7046c: If the data length of the character code is equal to the data bit width, it is judged that the additional character check digit is not set in the character code.

[0250] For example: if the set data bit width is 8bit, the data length of the obtained character code is 8bit, and the dat...

Abstract

The present application relates to a decoding method, a processor, a decoding device and a storage medium. The method includes: decoding the run-length coded data in the model data. Using this method can ensure the correctness of operation under the premise of data compression.

Description

technical field [0001] The present application relates to the technical field of statistical coding, and in particular to a decoding method, processor, decoding device and storage medium. Background technique [0002] With the continuous development of digital electronic technology, the rapid development of various artificial intelligence (AI) chips has higher and higher requirements for neural network processors. As one of the algorithms widely used in smart chips, the neural network algorithm runs on the neural network processor. [0003] However, due to the wide application of fixed-point and sparsification, a large number of continuous zeros usually appear in the model data, occupying a large amount of bandwidth resources and affecting the overall processing efficiency of the neural network processor. In the processing process of the processor, encoding technology is usually used to compress the redundant data, but the compressed data cannot directly participate in the ...
