TMS320F28386S: converting float values to send to UART takes forever

Hello,

I want to send float values via the serial port.

Consider the fallowing code:

void SendData(float a, float b, float c)
{
    #define bufLen  16
    uint16_t sendBuff[bufLen];

    sendBuff[0] = SOM1;
    sendBuff[1] = SOM2;

    sendBuff[2] = 0x00;

    GPIO_writePin(TEST_128, 0);
    loadDataToArray(&sendBuff[ 3], a);
    loadDataToArray(&sendBuff[ 7], b);
    loadDataToArray(&sendBuff[11], c);
    GPIO_writePin(TEST_128, 1);

    sendBuff[bufLen - 1] = EOM;

    SCI_writeCharArray(SCIA_BASE, sendBuff, bufLen);
}


void loadDataToArray(uint16_t * dest, float data)
{
    int * ptr = &data;

    dest[0] = *(ptr) & 0x00FF;
    dest[1] = *(ptr) >> 8;
    dest[2] = *(ptr + 1) & 0x00FF;
    dest[3] = *(ptr + 1) >> 8;
}

this code takes about 140us to run.

Any suggestion on how to do this process more efiisiantly?

Thanks!
