/* NAME */
/* DSP_q15tofl -- Q.15 to IEEE float conversion */
/* */
/* REVISION DATE */
/* 17-Jul-2001 */
/* */
/* USAGE */
/* This routine is C-callable and can be called as: */
/* */
/* void DSP_q15tofl (short *x, float *r, int nx) */
/* */
/* x[nx] --- Pointer to Q15 input vector of size nx */
/* r[nx] --- Pointer to floating-point output data vector */
/* of size nx containing the floating-point equivalent */
/* of vector input */
/* nx --- length of input and output data vectors */
/* */
/* DESCRIPTION */
/* Converts the Q15 stored in vector input to IEEE floating point */
/* numbers stored in vector output. */
/* */
/* void DSP_q15tofl (short *x, float *r, int nx) */
/* { */
/* int i; */
/* */
/* for (i=0;i<nx;i++) */
/* r[i]=(float)x[i]/0x8000; */
/* } */
/* */
/* The above C code is a general implementation without */
/* restrictions. The assembly code may have some restrictions, as */
/* noted below. */
/* */
/* TECHNIQUES */
/* unrolled loop 2x */
/* */
/* ASSUMPTIONS */
/* nx must be a multiple of 2 */
/* */
/* MEMORY NOTE */
/* no bank conflicts occur ever */
/* */
/* NOTES */
/* this routine is interrupt-tolerant but not interruptible */
/* this routine is ENDIAN NEUTRAL */
/* */
/* CYCLES */
/* 5/2 * nx + 18 */
/* */
/* CODESIZE */
/* 288 bytes */
