hi ,THIS IS THE CODE C of multiplier c= a*b using altf_mult in megawizard quartus :

void main( void)

{

float a ,b,c=1;

a=0x0EEEB0FF;

b=0xE1EEE5FF;

unsigned int EN;

EN=0x01;

IOWR_ALTERA_AVALON_PIO_DATA(PIO_A_BASE, a);

IOWR_ALTERA_AVALON_PIO_DATA(PIO_B_BASE,b);

IOWR_ALTERA_AVALON_PIO_DATA(PIO_EN_BASE,EN);

//

c=IORD_ALTERA_AVALON_PIO_DATA(PIO_RS_BASE);

//

printf("%f",c);

}

thank you
