This brings the total invested in Esperanto to $63 million.
The money will be used for the company's planned development of AI and machine learning chips in 7nm manufacturing process. The company had already revealed that it is planning an AI chip that is projected to contain more than 4,000 64bit processor cores on 7nm manufacturing technology.
Esperanto plans to use the open standard RISC-V Instruction Set Architecture (ISA) and other open standards such as the Open Compute Platform (OCP), Pytorch ML framework, Glow ML compiler, and the Open Neural Network Exchange (ONNX).
The company employs more than a hundred engineers, including AI experts, processor architects, chip designers, software developers and system engineers.
"Esperanto has assembled one of the most experienced VLSI product engineering teams in the ML industry, and we believe that will be a differentiating factor as we drive toward our 7nm products," said Dave Ditzel, CEO of Esperanto, in a statement.
In November 2017, Western Digital announced that it had made a strategic investment in Esperanto, and that it intends to transition its own consumption of processors – two billion cores per year – to the RISC-V architecture. "The RISC-V platform, and Esperanto solutions, free developers to innovate and optimize for special-purpose computing," said Martin Fink, CTO of Western Digital.
