The history of Virtuoso The history of Virtuoso Welcome to the world of Virtuoso. We think that you have purchased one of the most versatile and unique systems available for the implementation of a real-time system, be it on a single or on a multi-processor target system. Before we jump into the details, we would like to spend a few moments to explain the philosophy behind Virtuoso. In 1989, Intelligent Systems International (which later became Eonic Systems), was founded. At that time, the INMOS transputer was the only processor available with in-built support for parallel processing, however, it lacked the ability to support tasks with multiple levels of priority. In order to apply this technology to hard real-time applications, ISI wrote a multi-tasking kernel for the transputer. Derived from RTXC, ISI added support for multiple processors, and launched a product called TRANS-RTXC. In addition, ISI started to port to a variety of other processors. This was possible because TRANS-RTXC was redesigned much more with portability in mind, and re-named as RTXC/MP. It was available for targets ranging from 8- bit microcontrollers to 32-bit multi-processor networks. A major addition to the supported target processors was the Texas Instruments TMS320C30 and C40. This brought RTXC/MP into the DSP world, and to a new level of performance. However, the requirements of DSP applications needed a radical new approach in the implementation of the kernel. On the one hand, DSP applications running on hundreds of processors require a powerful and easily understood paradigm for distributed processing; while on the other hand the need to process interrupts from many sources requires an efficient, low-level approach. Often these apparently conflicting requirements are present in the same system. The result of these considerations was Virtuoso. The concepts behind Virtuoso are some of the most advanced, and they combine to give very powerful and efficient support for real-time, DSP and parallel system design. PART 3 The ability to use any of the kernel services to access a kernel object located on another processor in the system, no matter where it is located, frees the programmer from considering the details of interprocessor communication. Because the semantics of the kernel services were designed for distributed operation, it is the only system that guarantees that the deterministic behavior of the application is unchanged when the target network is changed. This paradigm is called the Virtual Single Processor, as it allows a multi-processor target to be programmed exactly as if it were a single processor. In the same context Virtuoso also provides multiple levels of support, allowing a trade-off to made of ease of programming for performance.
