e) Storing the data in a disk, and after ninthly, sending the data to MicroBlaze _1, MicroBlaze _2, MicroBlaze _3 and MicroBlaze _4 in sequence; after the MicroBlaze _1, MicroBlaze _2, MicroBlaze _3 and MicroBlaze _4 are received, the disk storage operation is started, and after the disk storage operation is completed, MicroBlaze _0 waits forAndall receive thenReporting to the CPU, finishing a data storage operation at the moment, and finishing a SATA address interaction; storing data in disk, after receiving the data, MicroBlaze _0 sends down (C) to MicroBlaze _1, MicroBlaze _2, MicroBlaze _3 and MicroBlaze _ 4; after the MicroBlaze _1, MicroBlaze _2, MicroBlaze _3 and MicroBlaze _4 are received, the disk storage operation is started, and after the disk storage operation is completed, MicroBlaze _0 waits forAndall receive thenReporting to the CPU, finishing a data storage operation at the moment, and finishing a SATA address interaction; data storage, MicroBlaze _0 receptionThen, the fifth, the sixth, the seventh and the seventh are issued to MicroBlaze _1, MicroBlaze _2, MicroBlaze _3 and MicroBlaze _4 in sequence; MicroBlaze _1, MicroBlaze _2, MicroBlazee _3, after the MicroBlaze _4 is received, the disk storage operation is started, and after the disk storage operation is finished, the MicroBlaze _0 waitsAndall receive thenReporting to CPU, finishing one data storage operation and one SATA address interaction.

f) Stopping data recording: a domestic CPU (APP _ STORE) issues a first step, wherein the first step comprises a channel shutdown instruction; the MicroBlaze _0 issues the second, third and fourth to MicroBlaze _5, MicroBlaze _6 and MicroBlaze _7 to turn off the channel; MicroBlaze _0 receives a ninthly; the fifth, the sixth, the seventh and the eighth parts of MicroBlaze _0 are sequentially issued to MicroBlaze _1, MicroBlaze _2, MicroBlaze _3 and MicroBlaze _ 4; MicroBlaze _0 will waitAndall receive thenReporting to the CPU to complete one SATA address interaction; MicroBlaze _0 receives r; the fifth, the sixth, the seventh and the eighth parts of MicroBlaze _0 are sequentially issued to MicroBlaze _1, MicroBlaze _2, MicroBlaze _3 and MicroBlaze _ 4; MicroBlaze _0 will waitAndall receive thenReport to CPU, finishing one SATA address interaction; MicroBlaze _0 receptionThe fifth, the sixth, the seventh and the eighth parts of MicroBlaze _0 are sequentially issued to MicroBlaze _1, MicroBlaze _2, MicroBlaze _3 and MicroBlaze _ 4; MicroBlaze _0 will waitAndall receive thenReporting to CPU to complete SATA address interaction.

g) CPU (APP _ STORE) receptionAnd updating the file system in real time to wait for the next read-write operation.

The data playback flow is similar to recording and will not be repeated here.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
