Edge AI, mired by fragmentation and an absence of broad availability of toolchains, is inching towards open architectures and open-source {hardware} and software program. This shift was obvious at Synaptics Tech Day on 15 October 2025, held on the firm’s headquarters in San Jose, California.
In different phrases, some edge AI processors are transferring away from proprietary, closed AI software program and tooling towards open software program and ecosystems to ship AI purposes at scale. Google’s collaboration with Synaptics embodies this open-source method to edge processors, aiming to ship AI intelligence at very low energy ranges.

Google, which constructed a mini-TPU ASIC for edge AI underneath the Coral model again in 2017, subsequently constructed the Coral NPU as a four-way superscalar 32-bit RISC-V CPU. Google is hoping that edge AI silicon suppliers will begin utilizing this small, light-weight CPU as a constant front-end to different execution items on an edge AI processor.
As a part of this initiative, Google has open-sourced a compiler and software program stack to port fashions from any ML framework onto the CPU. That permits silicon distributors like Synaptics to create an open-standards-based pipeline from the ML frameworks all the best way all the way down to the NPU front-end.
However the query is why RISC-V, particularly when Synaptics’ SL2610 processor is constructed round Arm Cortex-A55, Cortex-M52 with Helium, and Mali GPU applied sciences. Synaptics managers say that the transfer to RISC-V is meant to cut back fragmentation in software program stacks serving edge AI designs.
When requested about this, John Weil, head of processing at Synaptics, advised EDN that many semiconductor suppliers are using RISC-V cores, usually as helping cores, and most of the people don’t know that they’re even there. “On this case, it’s a way more performance-oriented RISC-V core to carry out neural processing.”
Synaptics tie-up with Google
In January 2025, Synaptics introduced it could combine Google’s ML core with its Astra open-source software program to speed up the event of context-aware units. The collaboration aimed to mix AI-native {hardware} with open-source software program to speed up the event of context-aware units.
Subsequent, Synaptics launched the Torq edge AI platform, which mixes NPU architectures with open-source compilers to set a brand new customary in edge AI utility improvement. Torq, leveraging an open-source IREE/MLIR compiler and runtime, has been vital in facilitating the deployment of Google’s RISC-V-based Coral open NPU within the edge AI processor Astra SL2610.

At Synaptics Tech Day, the corporate showcased the Astra SL2610 processor powering a number of edge AI purposes. That included e-bikes, EV charging infrastructure, industrial-grade AI glasses, command-based speech recognition, and good house automation.
Vikram Gupta, chief merchandise officer at Synaptics, advised EDN that when the corporate needed to go broad, it determined that this processor can be AI native. “Once we met with Google, it immediately resonated with us as a result of they had been engaged on Coral NPU, an open ML accelerator,” he stated. “We additionally needed to go open supply as a part of our AI-native processor story.”
Concerning Google’s curiosity on this collaboration, Gupta stated that Google advantages as a result of it has a silicon companion. “Google will get mindshare within the AI race whereas it’s outstanding within the cloud in addition to the sting AI.” Furthermore, Google might convey multimodal capabilities to this tie-up to allow extra context-aware consumer experiences, stated Nina Turner, analysis director for enabling applied sciences and semiconductors at IDC.
One other vital purpose of this silicon partnership is to confront fragmentation within the edge AI world. “Our take is that the one solution to sustain with AI innovation on the edge is to be open,” stated Weil of Synaptics. “Whereas some edge AI suppliers need the whole lot of their ecosystem, we’re targeted on how we knock down walled gardens.”
Concerning collaboration with Google, Weil added, “As an edge AI man, I must be working with guys working within the cloud, targeted on the subsequent large AI thought.” He additional summed up by saying that for Synaptics, the problem was how one can make {hardware} that retains up with the velocity of AI, open structure, and open supply. “So, we took Google know-how and matched it with ours.”
Open and collaborative
At a time when improvements in AI software program and algorithms are far outpacing silicon developments, an AI-native method to edge IoT processing may very well be vital in adopting contextual LLMs for audio, voice, textual content, and video purposes on the edge.
The launch of the Astra SL2610 processor, an AI-enabled system-on-chip (SoC) encompassing utility processor-level in addition to microcontroller-level components, marks an essential step within the availability of scalable, open methods for deploying real-world edge AI. These AI-native chips are anticipated to assist create an ecosystem that may simplify improvement and unlock highly effective new purposes within the edge AI realm.
“We consider that the one solution to sustain with AI innovation on the edge is to be open and collaborative,” Weil concluded.
