Booth's multiplication algorithm is a multiplication algorithm that multiplies two signed binary numbers in two's complement notation. The algorithm was invented by Andrew Donald Booth in 1950 while doing research on crystallography at Birkbeck College in Bloomsbury, London. [1] Booth's algorithm is of interest in the study of computer ...
Finally, multiplication of each operand's significand will return the significand of the result. However, if the result of the binary multiplication is higher than the total number of bits for a specific precision (e.g. 32, 64, 128), rounding is required and the exponent is changed appropriately.
A multiplication algorithm is an algorithm (or method) to multiply two numbers. Depending on the size of the numbers, different algorithms are more efficient than others. Numerous algorithms are known and there has been much research into the t

Andrew Donald Booth (11 February 1918 – 29 November 2009) [2] [3] was a British electrical engineer, physicist and computer scientist, who was an early developer of the magnetic drum memory for computers. [1] He is known for Booth's multiplication algorithm. [2] In his later career in Canada he became president of Lakehead University.
This leads to efficient implementations of add/subtract networks (e.g. multiplication by a constant) in hardwired digital signal processing. [1] Obviously, at most half of the digits are non-zero, which was the reason it was introduced by G.W. Reitweisner [2] for speeding up early multiplication algorithms, much like Booth encoding.

Here is a reference to Booth's paper: A. D. Booth. A Signed Binary Multiplication Technique, Quarterly Journal of Mechanics and Applied Mathematics 4 (1951), 236--240. This shows that Booth proposed his multiplication technique in 1951. The article gives a date of "around 1957". -James
