We often hear about RISC-V, its competitive open-source architecture, and how it is making inroads into the CPU industry. However, last year we reported on an open source GPU under development, which would seriously bolster the development of open-source graphics engines. This week Think Silicon announced that it is ready to “showcase the industry’s first RISC-V-based GPU.”
The new RISC-V 3D GPUs from Think Silicon will form the foundation of its Neox series. Two branches are already being readied to expand Neox offerings; the Neox G series for graphics acceleration and the Neox A series for accelerating deep learning tasks.
Why is Think Silicon purposing these two separate Neox branches? It is reasonable to assume that, as Think Silicon is a self-proclaimed “leader in ultra-low power graphics IP,” that it designs lean products strictly for targeted tasks. These won’t be flabby general-purpose GPUs.
Think Silicon’s press release gives us a few more clues to the type of embedded products and applications the respective Neox GPUs will target. It says that the new GPUs will feature customized SoCs for graphics, machine learning, vision/video processing, and general-purpose compute workloads. Mobile devices and platforms appear to be the most obvious, but not exclusive, target for this technology. Think Silicon reckons Neox G and A cores will be used in; next-generation smartwatches, augmented reality (AR) eyewear, video for surveillance and entertainment, and smart displays for point-of-sale/point-of-interaction terminals.
“Unveiling the first RISC-V-based GPU is a significant milestone for the graphics industry and for Think Silicon,” said Ulli Mueller, Director of IP Licensing, Sales, and Marketing at Think Silicon. Mueller added that he hoped developers coming to the exhibition would be inspired by his firm’s new 3D GPUs. In particular, he hopes that some will see the Neox GPU’s potential to create “exceptional user experiences” while being thrifty with power.
Think Silicon will demonstrate its RISC-V 3D GPU family at Embedded World 2022. This trade show takes place in Nuremberg, Germany, from Tuesday, June 21 to Thursday, June 23. It will be interesting to see the level of performance these early RISC-V GPUs can muster, albeit in the low-power and embedded segments.
Before we go, it is worth pointing out that the PC graphics industry big hitters like AMD are also looking at using RISC-V technologies in their product portfolios.
