TAU_PHASE_CREATE_STA(3) 				      TAU Instrumentation API					   TAU_PHASE_CREATE_STA(3)

NAME

       TAU_PHASE_CREATE_STATIC - Defines a static phase.

SYNOPSIS

       C/C++:

       TAU_PHASE_CREATE_STATIC(Phase phase, char* or string& function_name, char* or string& type, TauGroup_t group);

       Fortran:

       TAU_PHASE_CREATE_STATIC(integer phase(2), character name(size));

DESCRIPTION

       TAU_PHASE_CREATE_STATIC creates a static phase. Static phases (and timers) are more efficient than dynamic ones because the function
       registration only takes place once.

EXAMPLE

       C/C++ :

       int f2(void)
       {
	 TAU_PHASE_CREATE_STATIC(t2,"IO Phase", "", TAU_USER);
	 TAU_PHASE_START(t2);
	 input();
	 output();
	 TAU_PHASE_STOP(t2);
	 return 0;
       }

       Fortran :

       subroutine F2()

	 integer phase(2) / 0, 0 /
	 save	 phase

	 call TAU_PHASE_CREATE_STATIC(phase,'IO Phase')
	 call TAU_PHASE_START(phase)

	 call INPUT()
	 call OUTPUT()

	 call TAU_PHASE_STOP(phase)
       end

NAME

       mlib_SignalUpSample_S16_S16, mlib_SignalUpSample_S16S_S16S, mlib_SignalUpSample_F32_F32, mlib_SignalUpSample_F32S_F32S - signal upsampling

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_SignalUpSample_S16_S16(mlib_s16 *dst,
	    const mlib_s16 *src, mlib_s32 factor, mlib_s32 phase,
	    mlib_s32 n);

       mlib_status mlib_SignalUpSample_S16S_S16S(mlib_s16 *dst,
	    const mlib_s16 *src, mlib_s32 factor, mlib_s32 phase,
	    mlib_s32 n);

       mlib_status mlib_SignalUpSample_F32_F32(mlib_f32 *dst,
	    const mlib_f32 *src, mlib_s32 factor, mlib_s32 phase,
	    mlib_s32 n);

       mlib_status mlib_SignalUpSample_F32S_F32S(mlib_f32 *dst,
	    const mlib_f32 *src, mlib_s32 factor, mlib_s32 phase,
	    mlib_s32 n);

DESCRIPTION

       Each of these functions performs upsampling.

       For monaural signals, the following equation is used:

	 dst[i] = src[k]  if i == k*factor + phase
	 dst[i] = 0	  if i != k*factor + phase

       where k = 0, 1, ..., (n - 1); i = 0, 1, ..., (n*factor - 1).

       For stereo signals, the following equation is used:

	 dst[2*i]     = src[2*k]      if i == k*factor + phase
	 dst[2*i]     = 0	      if i != k*factor + phase

	 dst[2*i + 1] = src[2*k + 1]  if i == k*factor + phase
	 dst[2*i + 1] = 0	      if i != k*factor + phase

       where k = 0, 1, ..., (n - 1); i = 0, 1, ..., (n*factor - 1).

PARAMETERS

       Each of the functions takes the following arguments:

       dst	 Output signal array.

       src	 Input signal array.

       factor	 Factor by which to upsample. factor >= 1.

       phase	 Parameter that determines relative position of an input value, within the output signal. 0 <= phase < factor.

       n	 Number of samples in the input signal array.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
