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.

主題 : Low power Modified Booth Multiplier 介紹 : 為了節(jié)省乘法器面積、加快速度等等,許多文獻(xiàn)根據(jù)乘法器中架構(gòu)提出改進(jìn)的方式,而其中在1951年,A. D. Booth教授提出了一種名為radix-2 Booth演算法,演算法原理是在LSB前一個(gè)位元補(bǔ)上“0”,再由LSB至MSB以每?jī)蓚€(gè)位元為一個(gè)Group,而下一個(gè)Group的LSB會(huì)與上一個(gè)Group的MSB重疊(overlap),Group中的位元。 Booth編碼表進(jìn)行編碼(Booth Encoding)後再產(chǎn)生部分乘積進(jìn)而得到最後的結(jié)果。 Radix-2 Booth演算法在1961年由O. L. Macsorley教授改良後,提出了radix-4 Booth演算法(modified Booth algorithm),此演算法的差異為Group所涵括的位元由原先的2個(gè)位元變?yōu)?個(gè)位元。
