/* NAME */
/* DSP_blk_move -- Move a block of memory. Endian Neutral */
/* */
/* REVISION DATE */
/* 11-Dec-2001 */
/* */
/* USAGE */
/* This routine is C-callable and can be called as: */
/* */
/* void DSP_blk_move(const short *restrict x, */
/* short *restrict r, int nx); */
/* */
/* x --- block of data to be moved */
/* r --- destination of block of data */
/* nx --- number of elements in block */
/* */
/* DESCRIPTION */
/* Move nx 16-bit elements from one memory location */
/* to another. */
/* */
/* void DSP_blk_move(const short *restrict x, */
/* short *restrict r, int nx) */
/* { */
/* int i; */
/* for (i = 0 ; i < nx; i++) */
/* r[i] = x[i]; */
/* } */
/* */
/* ASSUMPTIONS */
/* nx greater than or equal to 4 */
/* nx a multiple of 2 */
/* Source and destination arrays are word aligned. */
/* Source and destination arrays do not overlap. */
/* */
/* TECHNIQUES */
/* Twin input and output pointers are used. */
/* Unrolled 4 times to use parallel LDWs and STWs. */
/* Peeled off half-iteration to allow mult. of 2 instead mult. of 4. */
/* Return branch issued from loop kernel to save cycles. */
/* */
/* NOTES */
/* This function is interrupt tolerant, but not interruptible. */
/* It locks out interrupts for its entire duration. */
/* */
/* MEMORY NOTE */
/* No bank conflicts occur in this code. */
/* This code is ENDIAN NEUTRAL. */
/* */
/* CYCLES */
/* cycles = MAX(2 * (nx >> 2) + 15, 21) */
/* For nx <= 14, cycles == 21. */
/* For nx == 16, cycles == 23. */
/* For nx == 100, cycles == 65. */
/* */
/* CODESIZE */
/* 128 bytes. */
