RISC-V ISA is an open source ISA currently developed and maintained by RISC-V International. IoT refers to physical devices connectivity, exchange, processing of data, etc. which is one of the fastest growing domains and expecting exponential growth in future. IoT requires many important factors like low power, security, etc. RISC-V provides many features which suits IoT well and provides advantages compared to other architectures. This whitepaper provides insight of the RISC-V and the advantages towards IoT devices and specifically on security features.
