At Embedded World 2025, Altera presented its Agilex FPGA families, Quartus Prime Pro and FPGA AI Suite as a platform for building customized edge-AI systems. The pitch is to combine reprogrammable hardware with AI processing close to sensors and actuators, targeting applications such as robotics, factory automation and medical equipment where latency, power, size and long service life matter.
What Altera announced at Embedded World 2025
Altera’s announcement centered on a development platform rather than a single AI chip: Agilex FPGAs provide configurable hardware, Quartus Prime Pro is used to design and integrate that hardware, and FPGA AI Suite helps map supported neural-network models to FPGA logic. Altera named robotics, factory automation and medical equipment as target applications, emphasizing their need for low latency and power consumption in compact, long-lived embedded systems.

The underlying approach is to configure data paths and control logic for a particular application, keeping processing near the devices that generate or consume the data. Unlike a fixed-function accelerator, FPGA logic can be reconfigured as requirements change. That flexibility is useful when a product’s sensors, control behavior or AI model may evolve during its service life, although changing a design still requires engineering work and validation.
How the Agilex families fit the edge-AI pitch
Agilex 3: low-power, cost-oriented designs
Altera describes Agilex 3 as a low-power, cost-optimized family for intelligent-edge applications. Altera’s 2025 announcement claims up to 1.9 times higher fabric performance and up to 38% lower power than the previous generation. These are vendor comparisons, not guarantees for every part or workload; the announcement does not establish an independent, apples-to-apples comparison of complete edge-AI systems.

Agilex 5: AI-capable fabric and compact options
Embedded reported in 2024 that Agilex 5 was Altera’s first FPGA with AI capabilities infused throughout the fabric, alongside small-form-factor options and development kits. The report also described a product claim of up to two times better performance per watt versus competing 7 nm FPGAs. Treat that as a reported vendor or product claim, not an independent benchmark across complete systems. Embedded’s 2024 report on Altera and Agilex 5
Why use an FPGA for edge AI?
The case for an FPGA is strongest when an application needs more than model inference alone: it may need tightly timed control, custom sensor handling, or specialized interfaces in the same design. The trade-off is that performance and efficiency depend on the chosen device, the implementation and the development team’s expertise.

- Latency and predictable timing: A fixed streaming pipeline can process data as it arrives and deliver predictable response timing, which can be valuable in control loops. Actual end-to-end latency depends on the design and system.
- Power and thermal constraints: Altera’s Agilex messaging emphasizes low power and compact embedded form factors. Whether a design meets its thermal and power targets must be assessed for the specific board, workload and operating conditions.
- Adaptability: Reprogrammable logic can be updated to accommodate changing models, sensors or system requirements. Updates still require redesign, testing and deployment planning.
- Integration: FPGA fabric, embedded processors, interfaces and AI blocks can be combined in an SoC or board-level design, allowing developers to tailor how data moves through a system.
- Development effort: The benefits depend on the compiler and tool flow as well as FPGA skills. Altera’s software tools are a central part of its pitch because model support and hardware mapping affect how practical the platform is for a given team.
Can FPGA AI Suite run PyTorch or TensorFlow models?
FPGA AI Suite supports optimization workflows based on PyTorch, TensorFlow and OpenVINO, according to Altera. That does not mean every model can be deployed unchanged: the supported model operations, mapping options and resulting implementation depend on the software release and the target device. The resulting AI intellectual-property blocks are integrated into a Quartus design, so this is a hardware-development flow, not simply installing a framework on an FPGA. Altera FPGA AI Suite
In release 2026.1.1, Altera added spatial mapping, which places neural-network operations directly into FPGA hardware for streaming dataflow. Altera says the approach supports deterministic latency and lower power. The release supports Quartus Prime Pro 26.1 and allows license-free early-stage development for up to 100,000 consecutive inferences, according to Altera’s release information. That inference allowance is a stated early-development limit, not a general claim that all development or production use is license-free. Check the current compatibility and licensing terms before starting a project. Altera FPGA AI Suite release information

Choosing an Agilex development kit for prototyping
Start with the application requirements, then confirm the exact device and board support in the current FPGA AI Suite and Quartus documentation. Agilex 5 development kits are described in Embedded’s 2024 coverage, but that does not establish which specific kit is right for a project or whether a given board is currently available. The material cited here does not specify a current part-number-to-kit recommendation.
- Define the prototype: List the sensors, interfaces, control tasks, model and timing or power constraints you need to evaluate. A board that lacks a necessary interface can limit the usefulness of a prototype.
- Check tool and device compatibility: Confirm that the selected FPGA device and kit are supported by the FPGA AI Suite release and Quartus Prime Pro version you plan to use. For FPGA AI Suite 2026.1.1, Altera specifies Quartus Prime Pro 26.1.
- Verify the board configuration: Check the current manufacturer or distributor listing for the exact kit, board revision, included components and regional availability. Availability can change; broad reports of development-kit availability do not guarantee stock for a particular kit.
- Prototype the data path as well as inference: Test sensor input, preprocessing, model mapping and output or actuator timing together. An inference result alone does not demonstrate that a complete embedded system meets its constraints.
What the performance figures do—and do not—show
Altera’s Agilex 3 figures compare fabric performance and power with a previous generation; the Agilex 5 figure reported by Embedded compares performance per watt with competing 7 nm FPGAs. Those claims use different comparisons and should not be treated as directly interchangeable. The cited material does not provide an independent, apples-to-apples GPU or ASIC benchmark for a complete edge-AI system, so it cannot establish that Agilex will outperform those alternatives for a particular application.
