Unlocking Hardware Potential: High-Performance Device Driver Development
Offered for Linux / Windows / Android OS and Platforms
Offered for Linux / Windows / Android OS and Platforms
In any OS-based system, your innovative hardware is only as good as the device driver that controls it. The device driver allows the operating system to interface with the underlying hardware peripheral. A poorly written, inefficient, or unstable driver can lead to system crashes, crippling performance bottlenecks, security vulnerabilities, and a frustrating user experience.
Developing a robust driver requires a deep, specialized skill set that goes far beyond application-level programming, demanding an intimate knowledge of both kernel internals and hardware design.
At Embien, we support the entire cycle of embedded device driver development in a systematic yet agile manner. Different activities we do are:
We write drivers from the ground up for your unique, custom-designed peripherals, working from datasheets or even reverse-engineering legacy hardware.
We expertly port existing drivers to new operating systems (e.g., Windows to Linux), different processor architectures (x86 to ARM), or upgrade them to support new OS versions.
We profile and refactor existing drivers to resolve performance issues, achieving goals like sub-frame video latency, maximizing PCIe bus throughput, and minimizing CPU overhead.
Our quality process includes stringent testing methodologies, stress testing, and fault injection to ensure the driver is exceptionally stable and reliable in all operating conditions.
For intelligent peripherals, we develop the necessary device-side firmware, upload it when the device driver is loaded and ensure the devices works perfectly well with the OS.
We validate and ensure the developed driver is certified by the OS vendor. One such example is the WHQL certification process for windows device drivers to get the driver signed.
Our deep understanding of kernel architectures allows us to develop natively compliant and efficient drivers across all major operating systems.
We are experts in Windows (WDM, KMDF, UMDF), Linux (for servers and workstations), and macOS (including DriverKit and legacy I/O Kit extensions).
Our primary focus includes Embedded Linux (leveraging Device Tree, V4L2, ALSA) and Android (AOSP), developing custom Hardware Abstraction Layers (HALs).
We build high-performance time-critical deterministic drivers for hard real-time systems running QNX, VxWorks, Azure RTOS (formerly ThreadX), and eCos.
For low-end microcontrollers, we develop drivers for basic RTOSes such as FreeRTOS, μC/OS-II/III, Zephyr, and MQX, as well as for the bare-metal schedulers.
If a peripheral connects to a processor, then we can write the device driver for it. Our experience spans every class of device, bus, and interface found in modern embedded and computing systems.
Wireless drivers for Wi-Fi (up to 802.11ax), Bluetooth/BLE, Zigbee, LoRa, Cellular (LTE/5G), and wired drivers for NFC/RFID (ISO14443/15693), Ethernet, and more.
Display drivers (DisplayPort, HDMI, LVDS, DSI), single/multi-touch panel controllers, keyboards, mice, joysticks, and haptic feedback devices.
Camera drivers integrating with V4L2/GStreamer, audio codecs (AC'97, I2S, SoundWire), hardware video accelerators, and TV/Radio tuners.
Complex bus drivers for PCIe, USB (Host, Device, OTG), I2C, SPI, CAN, and UART. We have achieved maximum theoretical throughput on many of these buses.
Drivers for all range of MEMS sensors including Accelerometers, Gyroscopes, Magnetometers (Compass), Barometers, and various environmental sensors.
Drivers for SATA (AHCI), NVMe, eMMC, MMC, SD/SDIO, DiskOnChip, CF Card, USB Drives, EEPROM, custom NAND flash and NOR flash memory controllers.
Whether one needs Linux driver development, Windows driver porting, or Android driver integration, Embien is the trusted partner.
We are relentless in our pursuit of performance. Our drivers are designed for maximum data throughput, minimum latency, and low CPU utilization.
Our development is streamlined by strict coding standards, peer reviews, and a robust testing methodology, resulting in exceptionally stable drivers.
Our expertise across ARM, RISC-V, x86, and other architectures means we understand the hardware context in which our drivers operate.
We understand the entire system. We know how a driver interacts with the kernel, middleware (like GStreamer/V4L2), and the final application, ensuring seamless integration.
