Embedded Technology for Quantum-Secure Communications: A Custom Platform Based on BORA XPress

The evolution of quantum communications is opening new frontiers in cybersecurity. By leveraging the principles of quantum mechanics, these technologies enable the creation and distribution of cryptographic keys with unprecedented levels of security, making any interception attempt immediately detectable.

Bringing such advanced technologies into mission-critical environments requires a robust, high-performance electronic platform capable of handling complex data processing, precise timing synchronization, and reliable system integration.

To address these challenges, DAVE Embedded Systems designed and validated a custom hardware platform based on the BORA XPress System on Module (SOM), providing the performance, flexibility, and reliability required for next-generation secure communication systems.

The Challenge

Quantum communication applications impose stringent requirements on the underlying electronic infrastructure. The processing platform must be capable of acquiring, managing, and distributing data in real time while maintaining exceptional levels of reliability and determinism.

The system needed to provide:

• High processing performance
• Multiple digital and analog interfaces
• Precise timing and synchronization capabilities
• Robust operation in demanding environments
• Scalability and future-proof architecture
• Reduced development time

Rather than investing engineering resources in the complete design of a custom processing board, the customer chose to rely on DAVE's expertise to accelerate development and reduce project risks.

The DAVE Solution

At the core of the platform is the BORA XPress SOM, a high-performance system that combines a dual-core ARM Cortex-A9 processor with a Xilinx Zynq FPGA, delivering both powerful software processing and hardware programmability within a compact footprint.

Starting from this proven module, DAVE developed a fully customized carrier board tailored to the specific requirements of the application.

The project encompassed:

Hardware Architecture

• Definition of the overall system architecture
• Functional requirements analysis
• Selection of interfaces and components
• FPGA resource allocation and I/O planning

Electronic Design

• Complete schematic development
• Power subsystem integration
• High-precision clock management
• Digital and analog interface design
• Dedicated connectivity for external subsystems

PCB Layout

• High-density multilayer PCB design
• High-speed signal routing
• Controlled impedance implementation
• EMC and signal integrity optimization

Prototyping and Validation

• Prototype manufacturing
• Hardware bring-up
• Functional verification
• Interface validation
• Software and FPGA integration support

This comprehensive approach provided the customer with a ready-to-integrate platform, significantly reducing development complexity and time-to-market.

What the Platform Does

The custom platform developed by DAVE acts as the processing core of a secure quantum communication system.

Its capabilities include:

• Managing communication and security algorithms
• Coordinating optical and acquisition subsystems
• Handling timing and synchronization functions
• Collecting and distributing data from external devices
• Performing real-time processing through the combination of CPU and FPGA resources
• Providing Ethernet connectivity and dedicated interfaces for complex subsystems

The combination of ARM processing and FPGA acceleration allows computational tasks to be efficiently distributed between software and programmable logic, maximizing both performance and power efficiency.

This architecture is particularly well suited for applications requiring high-speed data processing, low latency, and long-term reliability.

The Value of BORA XPress

The adoption of the BORA XPress SOM significantly accelerated project development.

Compared to a fully custom SoC-based design, the module offers:

• Proven and validated hardware
• Integrated memory and power management
• Reduced development risk
• Faster design cycles
• Simplified industrialization
• Easier maintenance and future upgrades

As a result, engineering resources could remain focused on the application's unique technological innovations rather than the complexity of embedded hardware development.

Why Partner with DAVE

One of the key success factors of the project was enabling the customer to concentrate entirely on their core intellectual property.

While DAVE handled hardware design, validation, and platform integration, the customer's engineering team was able to focus on:

• Development of proprietary algorithms
• Innovation of quantum communication technologies
• Application-level validation
• High-value research and development activities

This collaboration generated several tangible advantages.

Faster Time-to-Market

Leveraging a proven SOM and an experienced embedded partner significantly reduced overall project timelines.

Reduced Project Risk

Using a validated hardware platform minimized technical uncertainty and accelerated system integration.

Improved Engineering Efficiency

Internal teams could dedicate their efforts to innovation rather than embedded infrastructure.

Deep Technical Expertise

DAVE provided expertise spanning electronic design, FPGA development, Linux embedded systems, and low-level software integration.

Future Scalability

The modular architecture enables future evolution of the platform while preserving core design investments.

From Concept to Operational System

This project demonstrates how a modular embedded platform can accelerate the development of highly innovative technologies, even in the most demanding application domains.

By combining the flexibility of the BORA XPress SOM with DAVE's expertise in custom electronic design, a complex set of requirements was transformed into a validated, operational platform ready for integration.

For organizations developing next-generation technologies, the true value lies not only in the hardware itself but in the ability to focus engineering efforts on the innovations that make their solutions unique. By entrusting embedded platform development to an experienced partner, innovation accelerates, risks are reduced, and the path to market becomes faster and more efficient.
