Designing with Embedded Processors and Microcontrollers
There can be multiple instances of a System Generator pcore in an XPS project. Each of the
instances is associated with a device ID, which can be found in “xparameter.h”. Assume
that the instance of interest has a device ID of 0 based on the following information in
“xparameter.h”.
/* Definitions for driver SG_PLBIFACE */
#define XPAR_SG_PLBIFACE_NUM_INSTANCES 1
/* Definitions for peripheral SG_PLBIFACE_0 */
#define XPAR_SG_PLBIFACE_0_DEVICE_ID 0
Use the device ID of a System Generator pcore instance to select the corresponding item in
RGB2GRAY_PLBW_ConfigTable, which is then provided to xc_create to retrieve the
settings of the specific System Generator pcore instance.
The topic Integrating a Processor with Custom Logic contains more information on how
the hardware is wired up and other software issues.
Running the code will produce the following print out on a RS232 terminal.
