SCALEXIO Processing Unit

The newest processor technology

The SCALEXIO Processing Unit is the computing core of a SCALEXIO hardware-in-the-loop simulator, connecting the real-time model with the relevant I/O. All real-time applications, i.e., plant models and I/O interfaces, are calculated on it for ECU verification.

The SCALEXIO Processing Unit is based on an industrial PC with either an Intel XEON E5 octa-core processor or an Intel XEON E3 quad-core processor, a real-time operating system (RTOS), and a PCIe plug-on card developed by dSPACE for communication with the I/O and with other real-time processors. Because the processor and motherboard components are standard components, they can be updated regularly to benefit from performance improvements in processor technology.
To ensure communication between the real-time application running on the processor and the I/O, dSPACE offers the SCALEXIO Real-Time Library, which is based on the QNX® real-time operating system.

Multicore Support for Large Models

Depending on the processor, large, complex simulation models can be distributed across three or seven processor cores instead of one to ensure that they can be computed in real time. One core is reserved for internal system services. The configuration software ConfigurationDesk is used to distribute model parts to the cores and to configure the communication behavior, the simulation hardware, and the model connections.

IOCNET

SCALEXIO's communication network IOCNET (I/O Carrier Network) uses a proprietary dSPACE protocol to guarantee the simulator's real-time capability. It is the interface to the I/O boards and SCALEXIO processing units, providing a flexible network topology and high bandwidth to connect a large number of I/O boards, even when they are far apart.

Large Test Systems via Multiprocessor Support

With the multiprocessor support for SCALEXIO, two or more SCALEXIO systems can be coupled to increase computational power. To provide large bandwidths, SCALEXIO systems can be coupled to processing units via IOCNET. To ensure convenient modeling, you still have just one overall project in ConfigurationDesk.

Together, SCALEXIO LabBox and the Processing Unit provide a fully adequate HIL system for function developers and function testers. For this, the desktop version of the Processing Unit is used. The two devices are connected via IOCNET. The desktop and the rack-mount versions of the SCALEXIO Processing Unit provide the same technical features. The only difference is the rubber pads on the desktop version and the rack brackets on the rack-mount version.

IOCNET Link Board

The DS2502 IOCNET Link Board is used to connect I/O units or couple SCALEXIO systems with other dSPACE HIL simulator systems. It is available in two versions: one with 4 and one with 8 IOCNET connectors.

The DS2502 also has angular processing unit (APU) functionality for highly precise angle-based simulation, for example, to measure injection and ignition signals. Up to six independent APUs can be used.

Host PC Interface

Communication with the host PC runs via Gigabit Ethernet, so that the SCALEXIO system can be used in any company network. When more than two SCALEXIO Processing Units are used, they are coupled via the SCALEXIO MP Switch to ensure communication with the host PC. The IP address for the connection can be assigned via a DHCP server or stored on the SCALEXIO system itself.
