Texas Instruments Inc. debuts HawkBoard, an open source embedded processor development board based on the OMAP-L138 processor. Offering portability and diversity in its small, 9x10-cm form factor, the HawkBoard, enables Linux developers to harness the power of floating-point DSP to design unique open source applications.

This flexible, user-friendly, low-cost development board provides processing power through a robust ARM and digital signal processor (DSP) and has multiple expansion and interface options to allow users to create end-use applications such as portable test and measurement systems, portable medical devices, public safety and military radios, power protection systems, networked audio/video servers and receivers, VoIP solutions and Qt development applications.

Developers can utilise ARM without DSP with TI's pin-for-pin compatible AM1808 microprocessor from the Sitara family of processors. This low-power board requires only a 5V power supply, allowing portability by connecting to a laptop.

OMAP-L138 processor integrates an ARM 926 applications processor and C674x floating-point digital signal processor, delivering up to 450MHz performance. Two processors in a single package increase board space savings and offer developers processing efficiency by allowing the ARM to support complex operating systems and the DSP to handle high-precision data processing. Other features and benefits include 128MB of DDR2 RAM and 128MB of NAND flash; large on-board memory that allows developers to run multiple applications on an open platform; built-in SATA controller that supports SATA I and II interfaces as well as built-in MMC/SD; allowing developers to connect a high capacity storage drive or other memory interfaces; JTAG interface; provision for low-level debugging and read/write software and data into system memories.

The HawkBoard has two integrated USB ports, including USB on-the-go (OTG). Power can be driven by PC or laptop, and developers can easily plug and play other USB-enabled devices.

It facilitates a seamless audio and video experience with stereo audio in/out and video (VGA) in/out interfaces. It contains serial interfaces and additional expansion ports (SPI, UPP, PRU, VPIF, GPIO, UART, I2C, LCDC, eCAP and eHRPWM) and allows communication with numerous devices and customisation for proprietary interface

The HawkBoard is available for global shipping today from Farnell.
