Creating a custom IP and integrating to Microblaze

Hi,

FPGA is used for various applications which involves complex processing and control of other devices. Typically, FPGA logic resources are used to do complex processing (using Verilog/VHDL hardware description languages) whereas a soft-processor like Microblaze is used to control other devices.

The following link is very useful which gives hands-on lab experience with emphasis on concepts and their implementation in EDK.

Xilinx Document :

Chapter 6 explains how to create a custom IP and integrate it with EDK.

As a continuation of this Xilinx tutorial, I would like to explain how to access custom IP from a C code.

Xilinx provides Xil_Out8 API to write to a particular address in EDK design.

Definition of function is as follows:

void Xil_Out8(uint32 address=,uint8 data);

Eg: Xil_Out8(2019557376=,255);

Note: Do not forget to include #include "xil_io.h" to use these API's.

The following link has information of all other API from Xilinx.
