RTXC Quadros

QSI's RTXC Quadros real-time operating system is a second-generation RTOS composed of two major architectural modules: a Single Stack kernel and a Multi-Stack kernel. In RTXC Quadros, these classic real-time system design elements ensure a flexible RTOS configuration scaled to match the needs of a wide range of applications. Alone, both modules easily meet the demanding requirements of real-time, control processing or digital signal processing (DSP) applications. In combination, they answer the converging requirements of products spanning both application domains. The result is a RTOS architecture that achieves the ultimate in scalability, flexibility and performance.

Scalable Architecture

RTXC Quadros is a highly scalable architecture, the key to which is RTXCgen. By simple mouse clicks and structured dialog boxes, you can build the RTOS you want for your application. With RTXCgen, you can select the RTOS framework, the set of object classes that fit the application, the properties of those object classes, and even the exact set of services you want. And RTXCgen produces error-free source code representing your specification. No worries. No problems. Just the way you want it.

RTXC Quadros Architecture

  • Scalable to four RTOS frameworks
    • RTXC/ss, the single-stack framework
    • RTXC/ms, the multi-stack framework
    • RTXC/dm, the dual mode framework, a combination of both single and multi-stack frameworks
    • RTXC/mp, the multiprocessor framework
  • Supports 8-, 16-, 24-, and 32-bit microprocessors and microcontrollers, as well as 16-, 24- and 32-bit DSP engines
  • Support for up to 13 scalable object classes with over 330 scalable kernel services
  • Multiple scheduling models and policies
  • Small, scalable footprint to fit any ROM or RAM budget
  • Deterministic design for critical applications
  • Low overhead for maximum performance
  • Graphical configuration program, RTXCgen, for ease of building the exact RTOS configuration for your application
  • Integrated TCP/IP protocol stack, (RTXCnet), for easy application connectivity
Worry-free Application Development

QSI ports RTXC Quadros to a supported processor, and the code is bound to a specific compiler for that processor. You simply specify the supported processor and choose from our set of supported C compilers to begin productive, efficient application development right away.

As your application matures and grows to meet your market's demands, you'll appreciate that RTXC Quadros grows with you. You can begin with the single stack kernel, RTXC/ss, and add on the RTXC/ms kernel later on in a Dual Mode framework. And because RTXC Quadros share the same Application Programming Interface (API), regardless of the processor port, you'll be able to reuse your application code, preserving your development investment as you grow. By choosing RTXC Quadros, you get the most stable growth path for your application's future.

Outstanding Documentation

With RTXC Quadros, you'll also get some of the best user documentation in the industry. The documentation set includes detailed User and Reference Manuals that correspond to the major modules. There is a General Information manual, describing the architecture of RTXC Quadros at a high level. At a lower level, two User Guides explain the classes and operational theory for the Single Stack and the Multi-Stack frameworks, respectively. Separate Reference Manuals describe each kernel service you can use in each of the two major scheduling modules. And with extensive indexes and examples, these manuals will guide you through trouble-free use of this powerful real-time environment.
