FPGA Solutions for Defense Technology Development

Global instability is driving unprecedented investment in defense technology. From Central Europe to the Indo-Pacific, threats are both increasing and evolving. Consequently, all nations are looking to modernize their military capabilities and find technological advantages. This creates opportunities for companies developing innovative technologies.

At QBayLogic, we help innovators to quickly develop systems that secure critical infrastructure, guard our borders and, ultimately, defend our future freedom.

Where We Stand

We are deliberate about the defense work we take on. Our FPGA expertise contributes to systems that protect critical infrastructure, secure communications, sharpen sensing and situational awareness, and support trained operators in making better decisions under pressure — sensing, signal processing, cryptography, electronic warfare, and the high-speed data paths these depend on.

What we don’t do is build systems that remove humans from decisions about the use of force. Where our technology ends up in defense applications, it is designed to give the people responsible for those decisions better information and more time, not to take their place. That boundary shapes which projects we accept and how we work with our partners.

Fast Innovation for Critical Defense Systems

Defense technology contractors face great technological challenges. They develop systems that must process massive data streams with microsecond precision, often for applications that don’t yet have proven solutions. Whether you’re building free-space laser communication links, encrypted battlefield communications, or autonomous sensor platforms, you need partners who can translate complex requirements into working hardware and do it quickly enough to maintain competitive advantage.

This is where off-the-shelf computing solutions usually fall short. A CPU or GPU might theoretically provide sufficient processing power. But in a defense context, the difference between theoretical and practical performance is often the difference between a system that works when it has to and one that doesn’t.

Systems in defense applications must deliver guaranteed response times under all conditions. When a laser communication system is correcting for atmospheric turbulence, when a cryptographic processor secures battlefield communications, or when a sensor array tracks fast-moving objects, millisecond delays can mean mission failure.

Field Programmable Gate Arrays (FPGAs) excel in exactly these scenarios, and our expertise lies in translating your requirements into working FPGA implementations that deliver both the performance and the flexibility modern defense applications demand.

When Speed Becomes Mission-Critical

GPUs and CPUs can process data very quickly. But ‘quickly’ isn’t what defense applications need. What matters is predictability: knowing exactly how long processing will take, every single time. In an FPGA-based system, we can calculate precisely how long each operation will take. If data arrives at a specific moment, you know with certainty that the result will be available exactly, say, 10 nanoseconds later. Not approximately 10 nanoseconds, not usually 10 nanoseconds, but exactly 10 nanoseconds.

Consider a practical example: a laser communication system processing atmospheric turbulence data at 5,000 frames per second. Each frame must be analyzed, corrections calculated, and the laser adjusted. All within 200 microseconds. If processing takes too long, the correction is applied to atmospheric conditions that have already changed. This low-latency performance becomes even more critical as processing speeds increase. As one of our engineers noted during a recent project discussion: “Our technology becomes interesting from the speed of sound onwards.” Below certain velocities, embedded GPUs might suffice. But as systems move faster and latency demands grow, only FPGAs can deliver the guaranteed response times that defense applications demand.

Proven Defense Applications

Our work in defense applications and many dual-use technologies has given us direct experience with several applications at the forefront of modern defense systems. Here, we will list the most important ones.

Laser-Based Systems: From Communication to Defense

A focused laser beam can transmit large amounts of data while being extremely difficult to intercept. Unlike radio signals, which broadcast in all directions. This makes laser systems attractive for secure satellite-to-ground communications and other applications where data security matters.

The challenge lies in atmospheric turbulence. Air movement constantly distorts laser beams, scattering and refracting the light. What works perfectly in laboratory conditions fails in real-world deployment unless you can measure and correct for these distortions in real time.

This is where FPGA-based processing becomes essential. A laser beam spreads enough over distance that it must be captured by an array of lenses. Each lens has a focal point, and by analyzing how these focal points deviate from their expected positions, you can calculate the atmospheric distortion and adjust the outgoing laser to compensate.

Our FPGA-based systems process the data from lens arrays to calculate errors and generate corrections. This makes it possible to remove distortions from images, sharpen detection and tracking, and maintain a stable, high-quality link over long distances and through turbulent air.

Cryptographic Systems for Field Deployment

Encrypted communications represent another area where FPGA performance characteristics align with defense requirements. Military communications must be secured against sophisticated threats: state-level actors with significant resources dedicated to breaking encryption.

The computational demands of modern cryptography are substantial. Strong encryption requires complex mathematical operations and doing this in real time while maintaining low latency and low power consumption creates engineering challenges that traditional processors struggle to meet. This is where FPGA technology shines.

Signal Processing and Sensor Arrays

Our team includes engineers with experience at Thales, bringing expertise in signal processing and phased-array systems to defense-related projects.

Sensor arrays generate enormous volumes of data. Multiple sensors operating simultaneously, each producing high-frequency measurements, quickly overwhelm traditional processing architectures. FPGAs excel in this environment because they can process multiple data streams in parallel while maintaining the real-time performance that sensor applications demand.

The key is ensuring that data from multiple sensors is processed, correlated, and analyzed within the time constraints that make the information useful. This is where our experience with high-speed interfaces and parallel processing architectures becomes valuable.

Faster decisions under uncertainty

Modern military operations depend on timely, trustworthy information as much as on any other capability. The challenge is that information ages rapidly on the battlefield. By the time data is collected, transmitted, processed, and distributed, the situation has often changed. This ‘fog of war’ limits decision-making effectiveness. Real-time data processing, faster communication networks, and AI-enabled analysis all aim to provide commanders and operators with more and better information.

FPGAs contribute to this goal in multiple ways. In sensor systems, they enable real-time processing that reduces the time between detection and actionable information. In communication systems, they provide the low-latency, high-throughput processing that faster networks require. In autonomous systems, they allow rapid processing of multiple data streams—encrypted communications, sensor data, and AI models—all running concurrently with guaranteed performance.

A drone or unmanned ground vehicle, for example, might need to process encrypted command signals, analyze sensor data for navigation and obstacle avoidance, and run image recognition for object detection and situational awareness—all simultaneously and all with real-time constraints. Combining these capabilities in a single system requires the parallel processing and deterministic behavior that FPGAs provide.

As defense systems process more data, make faster decisions, and operate with greater autonomy, the value of FPGA-based solutions clearly increases.

The Integration Advantage

FPGA expertise alone isn’t enough for successful defense technology development. The FPGA must integrate with the broader system, and that integration must be right from the start. This is where many projects encounter unexpected delays and cost overruns.

We bring hardware expertise alongside our FPGA development capability. Our team can ask the right questions about your overall system architecture, make informed recommendations about how to arrange hardware for optimal performance and reliability, and work effectively with your existing hardware partners or connect you with specialists from our network.

This integration capability matters most at project boundaries—where the FPGA communicates with the outside world. Experience has taught us that this is where problems typically hide. Interfaces might be incorrectly specified, timing requirements misunderstood, or physical layer characteristics overlooked. Discovering these issues late in development is expensive and delays product delivery.

Our approach prioritizes early communication interface testing. Rather than building the complete FPGA design and only then attempting to connect it to external systems, we tackle the external interfaces first. This front-loads the risk: if problems exist, we discover them when schedule impact is minimal and solutions are still flexible.

This strategy has additional benefits. By establishing working communication with the outside world early, we can deliver partial products faster. Even if internal processing isn’t complete, you can see data flowing through the system, verify that interfaces work correctly, and begin integration with other subsystems. This reduces overall project risk and enables parallel development across your team.

We typically start with development boards for prototyping—standard FPGA platforms that already include common interfaces. This accelerates early development and lets us validate your requirements before committing to custom hardware. As the design matures, we work with PCB designers to transition to production hardware, making informed decisions about FPGA selection, pin assignments, and board layout based on actual measured performance rather than theoretical calculations.

Throughout this process, we maintain continuous integration testing. Automated tests run with every code change, immediately flagging anything that breaks existing functionality. This prevents the common scenario where problems accumulate silently until a major integration milestone reveals multiple issues simultaneously.

Why Work with QBayLogic?

Several factors distinguish our approach to defense technology development:

• Fast innovation cycles: FPGA development ‘the QBayLogic way’ allows rapid iteration. FPGAs can be reprogrammed and refined throughout development. We leverage this flexibility to deliver working prototypes quickly and incorporate feedback efficiently.
• Signal Processing Heritage: Our team includes engineers with Thales backgrounds, bringing experience with phased-array systems and other defense-relevant signal processing applications. This domain knowledge helps us understand your requirements in context and identify potential issues early.
• Integration Capability: we don’t just program FPGAs, we help design complete systems. Our hardware expertise means we can advise on overall architecture, work effectively with your hardware partners, or connect you with specialists from our network when needed.
• Iterative Problem-Solving: our development methodology emphasizes preventing recurring issues. Through single-source-of-truth architecture, abstraction of common functionality, automated testing, and careful tool selection, we build systems that are maintainable and reliable over the long term.

We understand that defense projects often involve requirements that haven’t been proven feasible, tight timeframes, and the need for absolute reliability once deployed. Our approach is built around these realities.
