TI-RTOS is an embedded tools ecosystem created and offered by Texas Instruments (TI) for use in a wide range of their embedded processors. It includes a real time operating system component called "TI-RTOS Kernel" (formerly known as "SYS/BIOS which evolved from DSP/BIOS") along with additional components that support device drivers, networking connectivity stacks, power management, file systems, instrumentation, and inter-processor communications like DSP/BIOS_Link.
TI-RTOS can be used within TI’s Code Composer Studio integrated development environment, IAR Systems' IAR Embedded Workbench, and the GNU Compiler Collection (GCC). Separate versions of TI-RTOS are provided to support TI's MSP43x (including MSP432), SimpleLink Wireless MCU, Sitara, Tiva C, C2000, and C6000 lines of embedded devices.
TI-RTOS provides a wide range of system services to an embedded application such as preemptive multitasking, memory management and real-time analysis. Because TI-RTOS can be used in such a wide variety of different microprocessors with very different processing and memory constraints, it was designed to be highly configurable.
