Introduction to RISC-V and the 32I Instruction Set RISC-V is an open and free instruction set architecture (ISA) that has gained significant popularity in microprocessor design due to its flexibility and efficiency. Unlike proprietary architectures, RISC-V allows developers and researchers to create custom processors without licensing restrictions. What is RISC-V? RISC-V is an architecture based on the Reduced Instruction Set Computing (RISC) principle, meaning it uses a simplified instruction set to improve hardware efficiency....

Selection of Hardware and Development Tools In this second article of the series, I will begin with the first steps in developing a RISC-V 32I-based microcontroller. For this, I have decided to use a Tang Nano 20K as the implementation platform. However, depending on resource usage, I might consider switching to a Tang Nano 9K if it meets the design requirements. Since the selected FPGA belongs to the Tang Nano family, this limits the development environment to compatible tools....
