Chapter 2: Hardware/Software Co-Design

Write Software

Create a new software application in your XPS project. Again, information on how to do

this can be found in the topic Using XPS. Add the following code to your application and

compile the software.

#include "xparameters.h"

#include "stdio.h"

#include "xutil.h"

// header file of System Generator Pcore

#include "rgb2gray_plbw.h"

int main (void) {

int i;

uint32_t gray, red, green, blue;

print("-- Entering main() --\n\r");

xc_iface_t *iface;

xc_from_reg_t *fromreg_gray;

xc_to_reg_t *toreg_red, *toreg_green, *toreg_blue;

// initialize the software driver

xc_create(&iface, &RGB2GRAY_PLBW_ConfigTable[0]);

// obtain the memory locations

xc_get_shmem(iface, "result", (void **) &fromreg_gray);

xc_get_shmem(iface, "red", (void **) &toreg_red);

xc_get_shmem(iface, "green", (void **) &toreg_green);

xc_get_shmem(iface, "blue", (void **) &toreg_blue);

for (i=15; i<30; i++){

red = i;

green = i + 10;

blue = i + 20;

// Write RGB value to peripheral

xc_write(iface, toreg_red->din, red);

xc_write(iface, toreg_green->din, green);

xc_write(iface, toreg_blue->din, blue);

xil_printf("R = 0x%x, G = 0x%x, B = 0x%x -- ",

red, green, blue);

xc_read(iface, fromreg_gray->dout, &gray);

xil_printf("Gray = %x \n\r", gray);

}

print("-- Exiting main() --\n\r");

return 0;

}
