WebMar 9, 2024 · Assuming 32-bit words, as stated in the question: For negative x, x >> 31 is implementation-defined in the C and C++ standards. The author of the code expects two’s complement integers and an arithmetic right-shift, in which x >> 31 produces all zero bits if the sign bit of x is zero and all one bits if the sign bit is one.. Thus, if x is positive or zero, … WebSep 19, 2012 · Therefore, shift your number left 4 bits (to multiply by 2^4 = 16), and add the original number to it. Another way to look at it is: 17 is 10001 in binary (base 2), so you need a shift operation for each of the bits set in the multiplier (i.e. bits 4 and 0, as above). I don't know C, so I won't embarrass myself by offering code. Share Follow

A barrel shifter is often used to shift and rotate n-bits in modern microprocessors, [citation needed] typically within a single clock cycle. For example, take a four-bit barrel shifter, with inputs A, B, C and D. The shifter can cycle the order of the bits ABCD as DABC, CDAB, or BCDA; in this case, no bits are lost. That … See more A barrel shifter is a digital circuit that can shift a data word by a specified number of bits without the use of any sequential logic, only pure combinational logic, i.e. it inherently provides a binary operation. It can however in … See more The number of multiplexers required for an n-bit word is $${\displaystyle n\log _{2}n}$$. Five common word sizes and the number of multiplexers needed are listed below: • 128-bit — $${\displaystyle 128\times \log _{2}128=128\times 7=896}$$ • 64-bit — See more • Kroening, Daniel; Strichman, Ofer (2008).
