Reduced Instruction Set Computer Architecture for IoT Devices
Reduced instruction set computer (RISC) architecture is a popular choice for IoT devices due to its energy efficiency and small footprint. RISC chips typically have a small number of simple instructions that are optimized for low power consumption. This makes them well-suited for IoT devices that need to operate on a small battery or that have limited power resources.
