RISC-V AI Chips Will Be Everywhere
spectrum.ieee.org, Feb. 24, 2022 –
The adoption of RISC-V, a free and open-source computer instruction set architecture first introduced in 2010, is taking off like a rocket. And much of the fuel for this rocket is coming from demand for AI and machine learning. According to the research firm Semico, the number of chips that include at least some RISC-V technology will grow 73.6 percent per year to 2027, when there will be some 25 billion AI chips produced, accounting for US $291 billion in revenue.
The increase from what was still an upstart idea just a few years ago to today is impressive, but for AI it also represents something of a sea change, says Dave Ditzel, whose company Esperanto Technologies has created the first high-performance RISC-V AI processor intended to compete against powerful GPUs in AI-recommendation systems. According to Ditzel, during the early mania for machine learning and AI, people assumed general-purpose computer architectures–x86 and Arm–would never keep up with GPUs and more purpose-built accelerator architectures.
"We set out to prove all those people wrong," he says. "RISC-V seemed like an ideal base to solve a lot of the kinds of computation people wanted to do for artificial intelligence."
