摘要
针对嵌入式系统中检验和计算过程复杂且效率低下的状况,文章实现了嵌入式系统中增量式检验和算法,有效提高了嵌入式环境下数据校验的性能,降低了数据校验过程的开销;实验结果表明增量式校验和算法可以满足嵌入式系统下数据校验的要求。
The cost of checksum calculation is very expensive in embedded system, which is becoming the bottle-neck of data processing in embedded system. Incremental Updating Checksum algorithm is designed and implemented in this paper. Experi-ments are carried out to contrast performance of data processing between Incremental Updating Checksum and Cyclic Redund-ancy Check（CRC）. The result shows the performance of Incremental Updating Checksum is better than CRC.
