Function Descriptions
3.30 Multiplication of a Real scalar and a Real Vector
Description:
This module multiplies a real scalar and a real vector.
Y [i] = C ∗ X[i]
Header File:
FPU.h
Declaration:
void mpy_SP_RSxRV_2(float32
*
y, const float32
*
x,
const float32 c, const Uint16 N)
Usage:
mpy_SP_RSxRV_2(y, x, c, N);
float32 *y
result real array
float32 *x
input real array
float32 c
input real scalar
Uint16 N
length of x and y array
Alignment Requirements:
None
Notes:
1. N must be EVEN and a minimum of 4.
Example:
#include "FPU.h"
#define N 10
float32 x[N], y[N];
float32 c;
main()
{
mpy_SP_RSxRV_2(y, x, c, N);
}
Benchmark Information:
Number of Cycles = 2*N + 15 cycles (including the call and return)
