Implementation, Verification and Validation of an Openrisc-1200
(IJACSA) International Journal of Advanced Computer Science and Applications, Vol. 10, No. 1, 2019 Implementation, Verification and Validation of an OpenRISC-1200 Soft-core Processor on FPGA Abdul Rafay Khatri Department of Electronic Engineering, QUEST, NawabShah, Pakistan Abstract—An embedded system is a dedicated computer system in which hardware and software are combined to per- form some specific tasks. Recent advancements in the Field Programmable Gate Array (FPGA) technology make it possible to implement the complete embedded system on a single FPGA chip. The fundamental component of an embedded system is a microprocessor. Soft-core processors are written in hardware description languages and functionally equivalent to an ordinary microprocessor. These soft-core processors are synthesized and implemented on the FPGA devices. In this paper, the OpenRISC 1200 processor is used, which is a 32-bit soft-core processor and Fig. 1. General block diagram of embedded systems. written in the Verilog HDL. Xilinx ISE tools perform synthesis, design implementation and configure/program the FPGA. For verification and debugging purpose, a software toolchain from (RISC) processor. This processor consists of all necessary GNU is configured and installed. The software is written in C components which are available in any other microproces- and Assembly languages. The communication between the host computer and FPGA board is carried out through the serial RS- sor. These components are connected through a bus called 232 port. Wishbone bus. In this work, the OR1200 processor is used to implement the system on a chip technology on a Virtex-5 Keywords—FPGA Design; HDLs; Hw-Sw Co-design; Open- FPGA board from Xilinx. -

Mostly IP (Intellectual property) cores are used for system development. In this paper, the IP core is designed with ALTERA NIOSII soft-core processors as the core and Cyclone III 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 III EP3C16F484C6 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. ---------------------------------------------------------------------------------------------------------------------------------------- Date of Submission: 8 April 2013 Date Of Publication: 25, April.2013 --------------------------------------------------------------------------------------------------------------------------------------- -
