View official documentation
Purpose:
Duplicates a scalar into every element of the destination vector.
Result:
float16x8_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
float16_t a = 2.5f;
float16x8_t result = vdupq_n_f16(a);
float16_t output[8];
vst1q_f16(output, result);
printf("%f %f %f %f %f %f %f %f\n", (float)output[0], (float)output[1], (float)output[2], (float)output[3], (float)output[4], (float)output[5], (float)output[6], (float)output[7]);
return 0;
}Prototypes
Assembly Instruction:
DUP
Usage:
float16x8_t result =
vdupq_n_f16(
float16_t a
)
