Semiconductor Engineering Article: Week In Review: Design, Low Power

This week Semiconductor Engineering made a round-up of notable news in the open-source world including RISC-V base ISA and privileged architecture specifications have been ratified by the RISC-V Foundation. Additionally, the RISC-V privileged architecture covers all aspects of RISC-V systems beyond the unprivileged ISA, including privileged instructions as well as additional functionality required for running operating systems and attaching external devices. Each privilege level has a core set of privileged ISA extensions with optional extensions and variants, including the machine ISA, supervisor ISA and hypervisor ISA.
