Houston, Tex. Quadros Systems, Inc. is porting its RTXC dual-mode RTOS to the Freescale ColdFire MCF532x and MCF537x processors.
With the convergent capabilities of the RTXC RTOS, developers can optimize both the dataflow and control characteristics of the Freescale processor family. Such optimization ensures the efficiencies of applications running on these new generation devices that greatly reduce hardware cost and power consumption.
With the dual-mode RTOS, Quadros is able to optimize both the RISC and DSP capabilities of the processor. By combining a lightweight executive, requiring minimal context for DSP processes, with a prioritized, preemptive kernel for event-driven tasks, RTXC/dm ensures that both RISC and DSP application code execute with maximum efficiency. The two kernel structures are organized by priority with dataflow processing controlled by a dedicated scheduler always operating at a higher priority than control operations.
“The number of applications requiring both DSP and control capabilities is burgeoning,” noted Tom Barrett, president of Quadros Systems. “System developers need to limit hardware costs while providing even more functionality. Convergent control/DSP architectures enable them to gain that edge, but it can only be maximized with a real-time operating system that knows how to optimize both capabilities in the same RTOS.”
“By using an optimized convergent RTOS rather than a traditional RTOS for applications using the entire processor/EMAC functionality, we can deliver as much as 40% greater application efficiency,” noted Stephen Martin, Quadros director of marketing. “Fewer processor cycles can translate into a lower cost processor with a reduced clock rate, or increased functionality supported on the same device with no additional hardware costs. Also, applications using our dual-mode RTOS can achieve much higher levels of responsiveness by giving the developer fine-tuned control over application tasks and processor utilization.”
The RTXC Quadros dual-mode RTOS is intuitive and easy to use. Developers planning to employ this advanced operating system do not require any specialized training. The powerful kernel objects and services are also fully manageable by the RTXCgen host-based configuration utility.
Quadros also provides extensive driver support for the full range of on-chip peripherals of the ColdFire MCF532x and MCF537x families, including USB host and device software development kits, GUI development library and LCD controller driver; TCP/IP stack (v4/v6) with Fast Ethernet driver, IPsec/IKE with support for onchip hardware acceleration, FAT file system as well as high-performance fail-safe flash file system. Development tools support includes CodeWarrior (v6) with kernel-aware debugging.
Quadros Systems solutions are scalable across the entire ColdFire family, reducing learning curve for new projects and preserving application code. For more information, visit www.quadros.com/coldfire.
Single-project licenses for RTXC/dm start at $15,500. Price includes a source code distribution and a Software Development Kit (SDK).
