This routine performs the bit-reversal of the input array x[], where x[] is a float array of length 2*nx containing single-precision floating-point complex pairs of data. This routine requires the index array provided by the program below. This index should be generated at compile time, not by the DSP. TI retains all rights, title and interest in this code and only authorizes the use of the bit-reversal code and related table generation code with TMS320 family DSPs manufactured by TI.
x | Complex input array to be bit reversed. Contains 2*nx floats | |
index | Array of size ~sqrt(nx) created by the routine bitrev_index to allow the fast implementation of the bit reversal | |
nx | Number of elements in array x[] |
