Bit reversal program in c
WebAug 2, 2009 · Method 2 – Standard: The idea is to keep putting set bits of the num in reverse_num until num becomes zero. After num becomes zero, shift the remaining bits of reverse_num. Let num is stored using 8 bits and num be 00000110.

However, in a comparison, any non-false value is treated is true. The ! operator does boolean inversion, so !0 is 1 and !1 is 0. The ~ operator, however, does bitwise inversion, where every bit in the value is replaced with its inverse. So ~0 is 0xffffffff (-1). ~1 is 0xfffffffe (-2).

In case bit-reversal is time critical, and mainly in conjunction with FFT, the best is to store the whole bit reversed array. In any case, this array will be smaller in size than the roots of unity that ... WebReverse bits of a given 32 bits unsigned integer. Note: Note that in some languages, such as Java, there is no unsigned integer type. In this case, both input and output will be given as a signed integer type. They should not affect your implementation, as the integer's internal binary representation is the same, whether it is signed or unsigned.

WebJan 5, 2012 · An efficient method of bit reversal is to exchange adjacent single bits, followed by exchanging adjacent 2-bit fields, followed by adjacent 4-bit fields, etc. For a 32-bit register, the final swap is on adjacent 16-bit fields, but more generally you want to stop at 2^(n-1).
