The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video.

BM 算法是一個(gè)較優(yōu)的模式匹配算法。一般,如果不考慮模式串的長(zhǎng)度,一個(gè)具有時(shí)間復(fù)雜度O(n)的算法應(yīng)該是最優(yōu)的了,但是事實(shí)不是如此。BM算法可以實(shí)現(xiàn)更高效率的模式匹配。分析和實(shí)驗(yàn)說明,BM匹配算法對(duì)于那些字符集比較大,而模式串中出現(xiàn)的字符比較少的時(shí)候,工作效率最快。而且,考慮KMP匹配方式的優(yōu)化,可以結(jié)合KMP匹配和BM匹配,進(jìn)一步提高效率。
