Description: Special Requirements
?nx must be a power of 2.
?The index array must be set up by bitrev_index before the function DSP_bitrev_cplx is called.
?If nx ?4K, one can use the char (8-bit) data type for the "index" variable. This would require changing the LDH when loading index values in the assembly routine to LDB. This would further reduce the size of the Index Table by half its size.
