Low power Modified Booth Multiplier
介紹 : 為了節省乘法器面積、加快速度等等，許多文獻根據乘法器中架構提出改進的方式，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前一個位元補上“0”，再由LSB至MSB以每兩個位元為一個Group，而下一個Group的LSB會與上一個Group的MSB重疊(overlap)，Group中的位元。
Booth編碼表進行編碼(Booth Encoding)後再產生部分乘積進而得到最後的結果。
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個位元變為3個位元。-Theme: Low power Modified Booth Multiplier Introduction: In order to save multiplier size, speed and so on, many papers multiplier in accordance with the framework to improve the way in which in 1951, AD Booth, a professor known as radix-2 Booth algorithm, algorithm theory is a bit LSB before the meeting on Platform: |

Description: A gate level implementation of a Booth Encoded Radix-4 24 bit multiplier with VHDL code in structural form. Carry-save adder and hierarchical CLA adder is used for the component adders in the design. The 12 partial products is a Wallace Adder Tree built from Carry-save adder using 3 to 2 reduction. A hierarchical CLA ( Carry-look-Ahead Adder ) adder is used for the final product generation.

Description: Due to its high modularity and carry-free addition, a redundant
binary (RB) representation can be used when designing high performance
multipliers. The conventional RB multiplier requires an additional RB partial
product (RBPP) row, because an error-correcting word (ECW) is generated
by both the radix-4 Modified Booth encoding (MBE) and the RB encoding.
This incurs in an additional RBPP accumulation stage for the MBE multiplier.
In this paper, a new RB modified partial product generator (RBMPPG) is
proposed; it removes the extra ECW and hence, it saves one RBPP
accumulation stage. Platform: |
