Real-Time COM Library for Windows
The idea of further abstraction (real-time communication for different communication interfaces, such as serial port communications, Ethernet (TCP / IP) and CANBUS (...) is realized with the SYBERA Transport Libraries, the so-called Real-Time cores. Each Real-Time core is on the X-Realtime Engine SYBERA. The core allows both, real-time Level1 (collecting and buffering of data at real-time, without loss of data), and Real-Time Level 2 (the cyclic functional operation at Real-Time). The Real-Time COM Library for Windows allows the handling of COM Raw data at real-time. In this case the real-time tasks can be embedded within the application. Data exchange takes place via a shared memory area. The Real-Time core only needs simple, passive harware. One of the great advantages is the adjustable scheduling time of incoming and outgoing data. A proprietary core interface, as well as the standard socket interface is available for the development of real-time applications. A fixed filter management enables the selection of individual COM data, as well as the transfer destination (core or COM interface). The available header files define all, for the processing of the core interface and the real-time interface necessary structures. The structural elements are combined hierarchically. The COM Realtime Core supports the PC internal, and external serial interfaces (PCI and PCMCIA OXFORD QUATECH and adapter) and is installed as a COM port device driver.
COM Master Functionality
At Realtime Level 1 inbound and outbound data are decoupled and controlled with the help of RX and TX ring buffers and forward and reverse indexing. Additional features of RealTime Level 2 allows the cyclical deterministic functional operation and the implementation of real-time protocols. Depending on the PC hardware and application, Real-time cycle times up to 50 usec may be realized. The COM Core enables the operation of multiple adapters at the same time. For each adapter an indexed COM stack is created.
COM Master Technology
The Real-Time COM Port Stack for Windows be installed as a COM device driver. SYBERA uses the method "Dynamic Jitter Compensation" with active and passive compensation within the realtime engine. Although the X-real-time Engine works with a maximum native jitter of ca. 15 microseconds (depending on the hardware platform), it can be reduced by the dynamic compensation to less than 3 microseconds.
