COA booth algorithm self doubt
Why we do right shift in booth algorithm? I know the working of booths algorithm. Suppose we have multiplicand M = 01011 and multiplier Q = 01110 We can write Q as (2^4 - 2^1). So multiplication reduces to 2^4(M) + 2(-M) Now booths algorithm rules ... ^4(M) + 2(-M) we multiply by 16 and 2 which requires left shift. So how is booths algorithm working with right shift ?

Booth Algorithm
Can anybody Explain why is it so that "The worst case of an implementation using Booth’s algorithm is when pairs of 01s or 10s occur very frequently in the multiplier." ?

BITS Assignment
Use the Booth algorithm to multiply +21 (multiplicand) by -24 (multiplier), where each number is represented using 6 bits. I tried but I'm getting answers as 000100100111 which converts into 295 but 504 even in -504 form is 1000000111, so I'm not sure where am I going wrong. please answer it

Doubt in Booth Algo and Bit pair recoding
Let's say we have a multiplier $ (10101010)_2 $. Then applying booth re-coding, Method 1: appending a zero at the end: $ (1\ 0\ 1\ 0\ 1\ 0\ 1\ 0\ 0)_2 => (-1\ 1\ -1\ 1\ -1\ 1\ -1\ 0)_2$ ... condition true? #multiplier bits must be equal to #multiplicand bits Please don't give any ref link because I've already searched but didn't got my doubt cleared.
