This process yields a bit vector with the same most significant 1 as x, but all 1's below it. Bitwise AND of the original value with the complement ...

"WebThe most well-known reordering technique involves explicit bit reversal for in-place radix-2 algorithms. Bit reversal is the permutation where the data at an index n, written in binary with digits b 4 b 3 b 2 b 1 b 0 (e.g. 5 digits for N=32 inputs), is transferred to the index with reversed digits b 0 b 1 b 2 b 3 b 4.

WebIf x is a matrix, the bit-reversal occurs on the first dimension of x with size greater than 1. y is the same size as x. [y,i] = bitrevorder(x) returns the bit-reversed vector or matrix y and the bit-reversed indices i, such that y = x(i). Recall that MATLAB uses 1-based indexing, so the first index of y will be 1, not 0. WebNov 21, 2007 · verilog reverse bit order HI Can anyone know how to reverse bits in verilog.
