Real-Time Operating Systems (RTOS) for TI Devices

TI's Microcontrollers as well as DSP and ARM® processors are supported by RTOS products from TI and its partners in the TI Design Network www.ti.com/designnetwork. TI provides the SYS/BIOS™ and DSP/BIOS™ real-time kernel at no charge. TI Design Network Products offerings range from minimalistic kernels optimized for microcontrollers to full-featured, memory protected operating ideal for microprocessors.


ARM RTOS Solutions

TI's Sitara™ ARM® Cortex™-A MPUs, C2000™ C28x + ARM® Cortex™-M MCUs, Tiva™ C Series ARM® Cortex™-M4 MCUs, and Hercules™ ARM® Cortex™-R Safety MCUs take full advantage of the ARM ecosystem.

  • TI's TI-RTOS real-time operating system and SYS/BIOS real-time kernel are complemented by many TI Design Network products.
  • These range from low footprint RTOS such as Micrium µCOS/III and FreeRTOS, which are ideal for Tiva C Series MCUs, to memory-protected and middleware-rich solutions like Wind River VxWorks, Mentor Nucleus, and QNX Neutrino that fully exploit the peripheral-rich Sitara ARM Cortex-A8 devices.
  • For safety-critical applications in transportation, aerospace, and medical arenas, TI Design Network products such as Green Hills Integrity and Wittenstein SafeRTOS can greatly reduce the cost of developing certified applications.
  • TI offers SYS/BIOS support for AM335x industrial applications:

MSP430 RTOS Solutions

The MSP430 family is supported by SYS/BIOS and by RTOS products from the TI Design Network. SYS/BIOS include special optimizations to help minimize power consumption. See RTOS table above for MSP430 RTOS products.

C2000 RTOS Solutions

The C2000 processor family, including the C28x + ARM Cortex-M3 family of C2000 + ARM Cortex M devices, is support by SYS/BIOS and DSP/BIOS. Third-party RTOS support for the ARM Cortex-M on C28x + ARM Cortex-M3 devices is listed in the table above.

DSP RTOS Solutions

All TI DSPs, as well as the DSP cores present on ARM+DSP devices, are supported by TI's SYS/BIOS and DSP/BIOS real-time kernel products, which are available at no charge and directly supported by TI.

  • Both SYS/BIOS and DSP/BIOS are fully integrated with the Code Composer Studio™ Integrated Development Environment (IDE) and support both single- and multi-core devices.
  • New DSP architectures, such as the C66xx, will only be supported in SYS/BIOS.
  • SYS/BIOS and DSP/BIOS support for ARM-DSP and DSPs families includes:
Single-Core DSP
Multicore DSP
