RISC-V: Redefining the Future of Computing, Architecture, Innovations, and Beyond

In recent years, RISC-V has gained significant popularity and RISC-V computing device is going to increase by 2030 due to open-source and royalty-free instruction set architecture (ISA). RISC-V is widely adopted as an ISA for embedded processors globally. India has launched the Digital India RISC-V (DIR-V) program for next generation microprocessors in 2022, and many organizations have started working on the RISC-VISA. The RISC-V standards organization consistently introduces new ISA extensions to cater to the evolving requirements of advanced computing. The widespread of use of Android/Wear OS is attributed to technological advancements and the availability of cost-effective solutions for mobile and wearable devices. There are many operating systems are available for embedded devices such as iOS, Android, Tizen and FireFox. Among all of these OS Android is one of the most popular OS for wide variety of devices such as smartphones, wearable, automotive, smart TV, etc. In this paper, we present the study of RISC vs RISC-V. Further, the details of challenges to run operating system especially linux kernel based OS on RISC-V is covered.
