The embodiment of the invention provides a data processing method and device, a storage medium and electronic equipment, and relates to the technical field of computers, and the method comprises the steps that a transmitting end obtains first I2S audio data, carries out the inter-frame splitting of the first I2S audio data, and obtains at least one first I2S data frame; encoding each first I2S data frame by using a Hamming code encoder to obtain an encoded second I2S data frame; the Hamming code encoder is used for encoding 4-bit data code words into 7-bit data code words, and data encoded by the Hamming code encoder is used for supporting error detection and error correction of the data; performing recombination according to the encoded second I2S data frame to obtain second I2S audio data; and sending the second I2S audio data to a receiving end based on an I2S protocol. Therefore, by grouping the frames and adopting (7, 4) Hamming codes for coding, the error correction capability is improved under the condition of increasing the minimum error correction bits, the reliable transmission of the I2S audio data is realized, and the hardware complexity is reduced.

The present application discloses a data backup method, device, equipment, medium and product. The method encodes the target data to obtain a first target code and a second target code, concatenates the first target code and the second target code to obtain a target cascade code, and saves the target cascade code so that in the event that the target data is lost, the target data can be restored through the target cascade code. Since the cascade code constructs a long code by serially cascading short codes, the length of the cascade code is less than the length of the long code constructed by a single structure and a single form of code, and therefore has the advantages of low decoding complexity, strong error correction capability and high coding efficiency. This technology can be used to solve the cache recovery problem when different nodes fall behind, and can maximize the decoding success rate under certain storage redundancy to achieve effective recovery after data loss.

The application provides a design method and device of a quantum sensor architecture, and a storage medium. The method comprises: receiving target signal specifications and environmental noise information; identifying a continuous symmetry group according to the target signal specifications and the environmental noise information; designing a quantum sensor configuration according to the continuous symmetry group; generating a measurement protocol that maintains symmetry protection based on the quantum sensor configuration, comprising: reconstructing a quantum state based on the quantum sensor configuration in the least number of times during the operation of the quantum sensor; and outputting a quantum sensor architecture specification based on the measurement protocol. Based on this, the immunity of the quantum sensor architecture to environmental noise can be enhanced, the standard quantum limit can be exceeded, and high sensitivity of the quantum sensor can be ensured.
