Progress in the TinyML Revolution
Over the past year, Efinix has been at the forefront of the TinyML revolution, enhancing the accessibility of machine learning on the ever-expanding portfolio of Efinix’s power efficient FPGAs. This has been transformative in environments where power efficiency and real-time processing are critical. Efinix's FPGA solutions are transforming industries from automotive to healthcare, marking a new era where AI extends beyond data centers to enable instantaneous decision-making at the edge.
The progress made in overcoming the challenges associated with Convolutional Neural Networks (CNNs) has been significant. CNNs, although powerful for tasks such as image recognition, demand substantial computational resources and are costly to train. Efinix tackles these challenges by optimizing CNNs for efficiency using its advanced FPGA technology, which boosts performance and expands their applicability at the edge.
AI Everywhere with Efinix FPGAs
Efinix has made “AI Everywhere” a reality by extending TinyML capabilities across the entire FPGA portfolio. From the compact Trion T20, ideal for energy efficient edge tasks, to the more powerful Titanium Ti60 and Ti180 suited for complex tasks, there's a FPGA for every project. Devices like the Trion T20 deliver advanced machine learning directly at the network's edge in the smallest of physical footprints and power budgets. The Ti60 and Ti180 demonstrate the same efficiency and AI capability while providing an FPGA fabric large enough for significant system integration reducing system bills of materials and overall system complexity.

As applications have become more complex, the compute needed for embedded AI and the system integration requirements have also grown exponentially demanding more and more capable FPGA platforms. Enter the Ti375—an FPGA that supports multiple AI models simultaneously. Featuring a quad-core RISC-V processor, it boosts performance by four while retaining custom instruction capabilities, crucial for real-time applications in smart cities, IoT, and automotive industries.
Central to Efinix’s innovations is the Sapphire RISC-V core—a flexible, high-performance processor architecture at the heart of our FPGAs.
We've expanded the Sapphire architecture to include both soft-core and hard-core RISC-V processors. Soft-core processors offer incredible flexibility and can be configured for diverse application needs. When performance demands increase, our hard-core processors step in, providing the compute needed for more demanding tasks and quadrupling the performance compared to their soft-core counterparts.
By providing both soft-core and hard-core processors and using the efficient RISC-V architecture, our FPGAs provide a range of compute capabilities while retaining the same energy efficient platform. This ensures that Efinix FPGAs are keeping up in the fast-evolving world of AI models and applications.
At Efinix, our mission remains clear: to continuously evolve with the expanding demands of AI technologies and to lead the edge computing revolution with our innovative solutions.
Fine-Tuning AI at the Edge with TinyML and Custom Instructions
Efinix’s TinyML platform uses TensorFlow Lite Micro (TFLite), a lightweight version of TensorFlow designed to run AI models on edge devices. TensorFlow, created by Google, is an open-source machine learning framework used to train AI models. After training, these models are converted into TFLite formats using post-training quantization, making them efficient enough to run on edge devices with minimal power consumption.
One of the key features of Efinix’s platform is the use of custom instructions, which allow developers to optimize the embedded RISC-V processor to the requirements of the AI models. By leveraging FPGA hardware acceleration, the platform handles compute-intensive operations—such as image recognition using convolutional neural networks (CNNs) or object detection with YOLO (You Only Look Once)—more efficiently than traditional GPUs or CPUs. This hardware-level optimization reduces latency and power consumption which makes Efinix FPGAs ideal in fields that require real-time insights with minimal delay.
For example, YOLO models are widely used for real-time object detection but typically require a lot of processing power. With Efinix FPGAs and RISC-V custom instruction acceleration, these models can run at the edge without draining the device's power resources.
Real-World Applications with the TinyML Profiler
Take a smart sensor in a manufacturing plant, for instance. It’s responsible for spotting anomalies in machinery, like temperature spikes or unusual vibrations. With Efinix’s FPGAs, the sensor can process data on the spot for real-time decision-making. If it detects an issue, it can immediately trigger safety measures to prevent equipment damage and reduce downtime. Plus, the reconfigurable nature of FPGAs means the hardware can adapt as AI models improve, offering a cost-effective and future-proof solution without needing hardware replacements.
Additionally, the Ti375’s quad-core architecture enables the simultaneous processing of multiple data streams. The Ti375 ensures real-time performance across a variety of edge applications like monitoring multiple machines in an industrial setting or managing multiple cameras in a smart city.
Time to market and ease of deployment is critical in these applications. Efinix has enhanced the deployment of TensorFlow Lite applications with a library of custom instruction accelerators designed to boost model performance. The Efinix TinyML Profiler automatically scans TensorFlow Lite models, identifying which accelerators from the library can best accelerate the application. These accelerators are seamlessly integrated into the developer’s project and compiled into the design. By automating all of the “heavy lifting” in the design optimization process, Efinix dramatically reduces time to market.
Building the Efinix Ecosystem
The vision of AI Everywhere is a future where edge devices are capable of processing data locally without relying on centralized cloud systems. As the world shifts towards this decentralized AI model, the demand for efficient, scalable platforms like Efinix’s FPGAs are growing.
