Aided design method used for shared data protection

Abstract

The invention discloses an aided design method used for shared data protection, relating to the field of computer aided design. The method comprises the following steps of: according to the core feature of each operating system, setting a rule feature table and an attribute feature table corresponding to each operating system; according to the name of the current operating system input by a user, selecting the corresponding current rule feature table and the corresponding current attribute feature table; according to a first order input by the user, extracting a current protection mechanism corresponding to the current shared data from the current rule feature table; according to a second order input by the user, selecting the current attribute feature description corresponding to the current shared data from the current attribute feature table; and presenting the current protection mechanism and the current attribute feature description for the user. The method reduces design burden and design risks of designers and solves the problems of high difficulty and high cost during follow-up error checking.

Description

technical field [0001] The invention relates to the technical field of computer aided design, in particular to an aided design method for shared data protection. Background technique [0002] Multi-processor and multi-core hardware platforms have been used more and more, and have become standard configurations in some fields. The corresponding operating system and software design must support this change, and the parallel design method should be adopted to give full play to the performance improvement space brought by the multi-core platform. If the shared data lacks protection or is not properly protected during concurrent operation, the shared data will be damaged at the least, and the system will crash at the worst. Therefore, the protection scheme of the shared data must be carefully designed. However, the operating system itself is becoming more and more complex, and the business processes to be realized by business software are also becoming more and more complex. Tho...

If the shared data lacks protection or is improperly protected during concurrent operation, the shared data will be damaged at the least, and the system will crash at the worst. Therefore, the protection scheme of the shared data must be carefully designed

However, the operating system itself is becoming more and more complex, and the business processes to be realized by business software are also becoming more and more complex. Those who are familiar with business processes are not necessarily familiar with operating systems (or not necessarily familiar with all operating systems), and those who are familiar with operating systems are not necessarily familiar with operating systems. Familiar with business process

[0003] Shared data protection is a difficult problem in software parallelization design. Insufficient protection will affect data integrity and operating system stability. Excessive protection will affect operating system performance, and the advantages of multi-core platforms cannot be fully utilized.

Therefore, the current shared data protection problem, on the one hand, increases the design burden and design risk of designers; on the other hand, if the protection is not proper, the difficulty and cost of subsequent troubleshooting are very high
