Experience with Device Drivers
Driver development has been a core part of Alumnus’s expertise – from devices to intelligent systems at the edge – across industries, platforms, and generations of hardware. From early device enablement to providing the foundation for software-defined ecosystems, our journey reflects a deep capability in managing complexity to deliver reliable, scalable solutions.
Making Devices Communicate
We have extensively worked at the foundational layer — developing drivers that enabled core device functionality across Wi-Fi, Bluetooth, Ethernet, and FPGA-based systems. From crafting SoftAP and SNMP-capable drivers to building Windows Miniport drivers for USB WLAN adapters, we helped devices “learn to speak” across interfaces like PCIe, SDIO, USB, and UART. These drivers established the baseline for performance, compatibility, and portability across diverse operating systems and chipsets.
Performance, Portability & Compatibility
A landmark engagement was our seven-year collaboration with a global semiconductor leader, focused on maintaining and modernizing Wi-Fi drivers across evolving kernel versions, hardware architectures, and deployment scenarios. We retrofitted emerging standards into legacy driver stacks, enabled seamless coexistence of Bluetooth and Wi-Fi through dual-stack integration, and engineered a unified codebase that supported rapid customization for diverse target configurations — significantly reducing time-to-market for new chipsets.
Advanced Systems featuring Multi-Core, Multi-OS
We’ve engineered communication between dissimilar OS, for example, Linux and an ITRON-based RTOS, running simultaneously on multi-core CPUs. With no hypervisor, we built shared memory channels and synchronization primitives that maintained task priorities and data reliability. The solution was capable of managing time-critical workloads without compromise, mandatory for industries like automotive and robotics.
Building Edge Intelligence Platforms
We work on platforms such as software-defined vehicles (SDVs) and V2X systems, where rich, secure, and low-latency communication is critical. Our experience spans building a car-to-car communication stack (802.11p) on real-time operating systems, addressing timing constraints in SDIO-to-Ethernet adapters, and porting the gPTP daemon for time-sensitive networking. We’ve adapted lightweight IP stacks like LWIP for media streaming use cases, ported libraries such as NGINX and wolfSSH to RTOS environments, and engineered unified driver solutions for multi-controller chipsets. Across these efforts, we’ve consistently simplified interfaces by managing timing, synchronization, cross-platform compatibility, and performance optimization.
