WebMar 21, 2012 · 1. For larger FFTs, paying attention to cache blocking (minimizing total uncovered cache miss cycles) can have a far larger effect on performance than optimization of the cycle count taken by indexing bit reversal. Make sure not to de-optimize a bigger effect by a larger cycle count while optimizing the smaller effect.

"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). If you think about it, a swap any larger than this is superfluous. " - Bit reversal program in c

WebSep 20, 2016 · 7 Answers. In C, true is represented by 1, and false by 0. 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). WebBasically, i want to reverse the bit order in a byte, so that the least significant bit becomes the most significant bit.
