RISC-V’s design is a revamp of the RISC concept that is intended from the ground up to fix the mistakes and learn from the lessons of the past 30 years. Power efficiency is 40% better than ARM or Intel. Compressed instructions reduce I-cache misses by 20-25%, which is roughly comparable to the same performance that would be achieved by doubling the Instruction Cache size. Yet despite El Reg’s insightful analysis,all is not as it seems: on further investigation, some of ARM’s criticism has merit, whilst some of it is clear out-and-out FUD from ARM that, being so critically dependent on free software, had its own employees complain so much that the site was pulled. Also we cannot help but wonder which “Big Chip” company offered seven-figure salaries to try to shut down the IIT Madras Shakti Project. Most interesting however is the fact that ARM — a $40 billion dollar company — is rattled by RISC-V enough to use underhanded tactics, whilst Intel on the other hand is actually investing.
