Booth's multiplication algorithm

摘要： fromhttp://en.wikipedia.org/wiki/Booth%27s_multiplication_algorithmHow it works Consider a positive multiplier consisting of a block of 1s surrounded by 0s. For example, 00111110. The product is given by: where M is the multiplicand. The number of operations can be reduced to two by rewriting the s. 阅读全文
