Texas Instruments releases open-source RTOS

23 January 2013 Computer/Embedded Technology

Texas Instruments is enabling microcontroller (MCU) developers to spend more time focusing on their unique applications, having developed TI-RTOS, a complete real-time operating system (RTOS) based on preemptive multithreading kernel, for its MCU platform.

TI has taken its expertise in its RTOS components, including the popular SYS/BIOS real-time kernel and network developer kit (NDK) TCP/IP stack, and integrated them to create a complete microcontroller RTOS. This new OS enables much faster software development by eliminating the need for designers to write and maintain complex system software, including schedulers, protocol stacks and low-level drivers.

Unique to the market, TI-RTOS provides a consistent embedded software platform across TI’s entire MCU portfolio, making it easy for developers to scale designs to update or add functionality by porting legacy applications to the latest processor. This consistent platform also benefits TI Design Network software ecosystem partners by providing a free, widely used software platform without proprietary constraints.

TI-RTOS provides a complete, mature and stable embedded operating environment that provides full middleware and driver enablement to add more product functionality.

Components of the environment include a deterministic, real-time multitasking kernel (SYS/BIOS); TCP/IP stack, including network applications; USB, EMAC, MMC/SD host and device stacks and class drivers; FAT-compatible file system fully integrated with C RTS file I/O functions; Ethernet, USB, UART, I²C and SD device drivers; and low overhead core-to-core communication mechanism for dual-core devices.

The software can be downloaded for free from www.ti.com
