Abstract

The invention provides computer equipment, a product, a data task processing method and a device thereof. The method comprises the steps: carrying out the cyclic redundancy check of local safety related data and / or input and output data, generating a first check value, and transmitting the first check value to a backup central processing unit; receiving a second check value which is sent by the backup central processing unit and is generated by performing cyclic redundancy check on the local safety related data and / or the input and output data, and comparing the first check value with the second check value. Therefore, the communication data volume is effectively reduced. The comparison efficiency is improved, and the operation efficiency of the CPU is improved under the condition of ensuring the comparison result.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for processing computer equipment, products and data tasks thereof. Background technique [0002] In the task-level two-out-of-two system, two two-out-of-two central processing units (CPUs, central processing units) need to compare local safety-related data with external input and output data to complete the two-out-of-two check. The usual comparison method is to send the input data, output data and local safety-related data of the two CPUs to the other party through the software set in the execution layer of the two-out-of-two system. After receiving the data sent by the other party, the two CPUs communicate with the local The saved data is compared, and then the comparison result is sent to the voter. The voter judges the vote according to the consistency of the comparison result. If the vote is successful, the control processor continues to ...
