Tom’s Hardware Article: RISC-V Foundation Trumpets Open-Source ISAs In Wake Of Meltdown, Spectre

The RISC-V Foundation says that no currently announced RISC-V CPU is vulnerable to Meltdown and Spectre and, in the wake of those bugs, stressed the importance of open-source development and a modern ISA in preventing vulnerabilities.

In consumer computing, we usually only hear about two instruction set architectures (ISA): x86 and ARM. Classified as a complex instruction set, x86 dominates the desktop and server space. Since the rise of smartphones, however, reduced-instruction-set (RISC) ARM processors have dominated the mobile computing market. Beyond x86, there aren’t many complex instruction sets still in use, but there are still many relevant RISC designs despite ARM’s seeming ubiquity.
