Design and Implementation of Embedded I/O System Based on MicroBlaze

The MicroBlaze embedded soft-core is of RISC architecture,optimized for implementation in Xilinx field programmable gate arrays(FPGA),using which the embedded system can be designed.The architecture of MicroBlaze is introduced and the procedure of embedded system development is analyzed based on MicroBlaze.The whole design scheme is brought forward about embedded I/O system,and the key problems involved in the design are discussed.
