Benefits of FPGAs over other options for AI and Machine Learning
No single architecture is best for AI, machine and deep learning applications, but in certain cases, FPGAs can offer distinct advantages over GPUs and other types of hardware.
What is an FPGA?
Field programmable gate arrays are semiconductor devices based around a matrix of configurable logic blocks. Unlike graphics processing units (GPUs) the circuitry inside an FPGA is not hard etched and as such, it can be programmed and reprogrammed as necessary.
Benefits of an FPGA?
The ability to be programmed or reprogrammed gives FPGAs a significant advantage in development when compared to developing custom application-specific integrated circuits (ASICs), which require time and money to design and fabricate.
Sundance has been working on a multitude of robotics projects and FPGAs are proving to be a great benefit in this area. Their low power consumption means they are ideal to be battery powered and the small form-factor of the chipsets makes it easier to find a position for them to be mounted. Using them on drones, not only is their relatively small size an advantage, but also their low weight.
In these robotics examples where the FPGA is performing tasks for object recognition and also navigation, the low latency of the FPGA enables the time of flight calculations to be more accurate.
FPGAs in Artificial Intelligence
Image recognition can rely heavily on parallelism, and as GPUs excel at parallel processing, using them for this AI task became popular. However, GPUs don’t deliver as much performance as an ASIC, a chip purpose-built for a given deep learning workload. FPGAs can be seen as the best of both worlds, they offer hardware customisation with integrated AI and can be programmed to deliver behaviour similar to a GPU or an ASIC.
The reprogrammable, reconfigurable nature of an FPGA lends itself well to a rapidly evolving AI landscape, allowing designers to test algorithms quickly and get to market fast. FPGAs offer several advantages for deep learning applications and other AI workloads: Great performance with high throughput and low latency: FPGAs can inherently provide low latency as well as deterministic latency for real-time applications like video streaming, transcription, and action recognition by directly ingesting video into the FPGA, bypassing a CPU.
Designers can build a neural network from the ground up and structure the FPGA to best suit the model. Excellent value and cost: FPGAs can be reprogrammed for different functionalities and data types, making them one of the most cost-effective hardware options available.
