TI Expands Successful Software Ecosystem with a New, Complete Real-time Operating System: TI-RTOS

TI-RTOS eases software development for microcontroller (MCU) designers, allowing them to take applications with greater functionality and connectivity to market faster

DALLAS -- Microcontroller (MCU) developers can spend more time focusing on their unique applications because software design just got easier.  Today, Texas Instruments Incorporated (TI) (NASDAQ:  TXN) furthers its investment in the embedded processing software and tools ecosystem with TI-RTOS, a complete real-time operating system (RTOS) based on preemptive multithreading kernel, for its MCU platform. With more than 20 years of experience in delivering production-quality operating system (OS) solutions for real-time applications, TI has taken its expertise in its RTOS components, including the popular SYS/BIOS(TM) 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.

"Embedded hardware development has become easier with the high level of integration MCUs now have," said Scott Roller, vice president, MCUs, TI.  "However, because of the integration of more peripherals, memory and connectivity options, software development has become more complex, which is why we created TI-RTOS. Now developers can build MCU-based designs with Internet and USB connectivity without the concern that software development will be onerous and time-consuming."

TI-RTOS features and benefits:

--  Ease software development with a complete, mature and stable embedded operating environment that provides full middleware and driver enablement to add more product functionality.  These components include:

-  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

-  Low overhead core-to-core communication mechanism for dual-core devices

--  Begin software development and achieve network connectivity straight out of the box with components that have been integrated and tested.  The user does not have to piece code together or face component version mismatches to get their application working in a multithreading environment.

--  Easily enhance an existing software base with new functionality by adding new tasks that do not disrupt the real-time response of critical system functions.

--  Move functions between dual core devices to optimize performance by using the same TI-RTOS kernel on both the ARM® and C28x DSP cores.

--  Receive robust documentation and examples to augment designs, including examples and APIs appropriate for multitasking development and integration to help evaluate TI-RTOS and receive training.

--  Meet on-chip memory constraints with an RTOS based on a modular architecture with a small footprint, enabling easy removal of software functionality not required in the application.  Components are also scalable, allowing for further reductions in memory requirements.

--  Enable seamless development in familiar environment. TI-RTOS is fully integrated with TI's Code Composer Studio(TM) integrated development environment (IDE) and contains board support packages and development kits, including the TI MCU LaunchPads.

--  Obtain application-specific software with TI's broad Design Network software developer network with partners such as Interniche and Simma software that provide additional communications stacks that work with TI-RTOS.

--  Benefit from no upfront or run-time license fees and free support with full C source code and direct support from TI.

TI's Design Network:  What our partners are saying about TI-RTOS

InterNiche Technologies

"With many microcontrollers now adding Ethernet capabilities, we have a tremendous opportunity to apply our networking expertise in that space," commented Larry Larder, president of InterNiche Technologies. "We will address microcontroller developers' concerns about network security and management by complementing the base TI-RTOS TCP/IP stack with additional protocols such as SSH, SSL, IPsec and SNMP. This means that TI customers using TI-RTOS and TCP/IP can easily add InterNiche preported management and security protocols. In addition, customers new to networked applications can benefit from our deep knowledge of how to diagnose and resolve networking problems."

Simma Software

"We have enjoyed great success providing our CAN solutions for all of TI's microcontrollers for a decade and already support the SYS/BIOS real-time kernel," stated JR Simma, CEO, Simma Software.  "TI-RTOS is a great solution to simplify development of today's increasingly complex microcontroller applications and provides us with a standard software platform to port our CAN solutions to."

Stonestreet One

"Stonestreet One, with our Bluetopia protocol stack, is a leader in Bluetooth solutions and has a long history of supporting TI devices with our products, which are already available on the SYS/BIOS real-time kernel for TI's ARM Cortex M microcontrollers," said Tim Reilly, CTO, Stonestreet One. "TI-RTOS represents a natural evolution from SYS/BIOS now that microcontrollers are commonly including connectivity options like USB and Ethernet. We are excited to support it."
