Detailed Description

DSP utils.

note, many functions in here may use MMX which trashes the FPU state, it is absolutely necessary to call emms_c() between dsp & float/double code

void ff_fft_calc_altivec ( FFTContext *  s,
FFTComplex *  z 
)

Do a complex FFT with the parameters defined in ff_fft_init().

The input data must be permuted before with s->revtab table. No 1.0/sqrt(n) normalization is done. AltiVec-enabled This code assumes that the 'z' pointer is 16 bytes-aligned It also assumes all FFTComplex are 8 bytes-aligned pair of float The code is exactly the same as the SSE version, except that successive MUL + ADD/SUB have been merged into fused multiply-add ('vec_madd' in altivec)
