Design of PS2 keyboard controller IP core based on SOPC

In this paper, the IP core is designed with ALT ERA NIOSII soft-core processors as the core and Cyclone II FPGA series as the digital platform, the SOPC technology is used to make the I/O interface controller soft-core such as microprocessors and PS2 keyboard on a chip of FPGA. NIOSII IDE is used to accomplish the software testing of system and the hardware test is completed by ALTERA Cyclone II EP2C35 FPGA chip experimental platform. The result shows that the functions of this IP core are correct, furthermore it can be reused conveniently in the SOPC system.
