Microcontrollers are everywhere, powering everything from your dishwasher to powerful computing systems and millions of wearable and IoT devices. For the processor cores and architectures, names such as ARM, AVR, MIPS, Xtensa, 8051, etc., dominate the landscape, each with unique strengths and areas of application. These platforms, used in many very popular microcontrollers such as the STM32, ESP32-S3, ATmega and so on, share a common trait: They are proprietary. Enter RISC-V, a relatively new player in the world of microcontrollers and processors.
