RTXC™ Supports MPC55xx Microcontroller Family

Real-time OS from Quadros Systems enables access to powerful features of this PowerPC™ processor line from Freescale

Houston, TX – May 19, 2009 — Continuously updating its extensive support for PowerPC processors, Quadros Systems, Inc., a leading provider of real-time operating systems (RTOS), today announced support for the MPC55xx series of 32-bit microcontrollers (MCUs) from Freescale Semiconductor. Developers can now combine the efficiency, flexibility and scalability of the RTXC software family with the low-cost, high performance MPC55xx family.

The MPC55xx is based on Power Architecture™ technology. On-chip integration features up to 1 MB of embedded flash memory and 64 KB on-chip static RAM. The MPC55xx family is well-suited for any developer that commands complex, real time control at a low cost. This series of microcontrollers is tailored specifically for industrial and automotive applications. The RTXC RTOS supports the following MPC55xx features:

• INTC (Interrupt controller)
• DEC (Decrementer)
• SPE (Signal Processing Extension)
• FIT (Fixed Interval Timer)
• eMIOS (enhanced Modular Input Output Subsystem)
• eSCI (enhanced Serial Communication Interface)
• SWI (SoftWare Interrupt)
• FMPLL (Frequency Modulated Phase Locked Loop)

Quadros offers a broad range of software solutions for Power PC and other embedded architectures including RTOS, design tools, 10/100 Ethernet software, USB software, file systems and LCD/graphics software. Known for its efficiency, high performance and small footprint, the RTXC family of solutions from Quadros provides an easy-to-use, flexible development and runtime solution for the MPC55xx processors.

The RTXC Quadros RTOS was ported to the MPC5534 using Freescale CodeWarrior for MPC55xx v2.3 toolchain. A Freescale MPC5534EVB Revision D evaluation board from Axiom Manufacturing was used as the qualification platform.

About the RTXC Quadros Family of Real-time Operating Systems
The RTXC Quadros RTOS is built on a legacy of more than 30 years of operating system experience. This powerful and flexible operating system family is designed to give the developer maximum control over system resources and application performance. The RTXC Quadros RTOS boasts more than 330 kernel services in a code footprint less than 30 KB. Features include:

• Multitasking with selectable scheduling policies (Preemptive, Round Robin, Time Sliced)
• Static and dynamic kernel objects
• Fixed or dynamic task priorities
• Intertask communication and synchronization (Semaphores, Mailboxes and Messages, Queues, and Pipes)
• Efficient management for “ticks” from internal or external sources
• Alarm options for many services
• Partitioned RAM management
• Priority inversion handling option for mutexes
• Efficient interrupt servicing
• Fast context switch
• Standard programmer interface in C on all processors
• Highly flexible configuration tool to adapt the RTOS to the application

The RTXC RTOS family is complemented by VisualRTXC, an easy-to-use, powerful design tool that allows the developer to rapidly move between design concepts and generated C code. In addition to the RTXC RTOS family, Quadros Systems offers a wide range of communications stacks and middleware including RTXCusb (RTOS-agnostic USB stacks and drivers) and RTXCflashfile (a high performance file system for resident flash devices). RTXC products have been deployed worldwide in hundreds of millions of embedded systems, serving markets such as communications, medical, and industrial automation.
