Implementation, Verification and Validation of an OpenRISC-1200 Soft-core Processor on FPGA

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 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 GNU is configured and installed. The software is written in C and Assembly languages. The communication between the host computer and FPGA board is carried out through the serial RS- 232 port.
