Free RTOS eases embedded design

4 March 2009 Design Automation

The increasing complexity of industrial applications and expanding functionality of semiconductors are driving embedded developers toward solutions that combine proven hardware and software platforms. To help accelerate time-to-market and improve application development success, Freescale is offering its MQX realtime operating system (RTOS) with TCP/IP and USB software stacks to ColdFire microcontroller (MCU) customers at no additional charge.

Freescale is now shipping its new MCF5225x ColdFire MCUs with a complementary, full-featured version of the RTOS and associated stacks, providing developers a comprehensive embedded platform for industrial connectivity. The MCF5225x family is the first line of Freescale embedded controllers to be combined with the MQX RTOS. In 2009 and beyond, the company plans to expand the availability of complementary MQX software across its portfolio of embedded processors and MCUs, such as other ColdFire devices, 16-bit digital signal controllers (DSCs), Power Architecture processors and i.MX application processors.

The MQX software offers an application programming interface (API) with a modular, component-based architecture that makes it simple to fine-tune custom applications. It also allows developers to add Web servers, e-mail, network management, security and routing to their designs. Components are linked in only if needed, preventing unused functions from bloating the memory footprint.

Unlike general-purpose operating systems designed for desktop systems, MQX was designed for speed and size efficiency in embedded systems. The software offers powerful, preemptive realtime performance with optimised context switch and interrupt times, enabling fast, highly predictable response times. Its configurable size conserves memory space for embedded applications, and it can be configured to take as little as 6 KB of ROM, including kernel, interrupts, semaphores, queues and memory manager.
