The quad-core DS1006 processor board from dSPACE features an AMD Opteron 2.8-GHz processor to increase the power of hardware-in-the-loop (HIL) simulation and perform up to 60% faster. Large models can be distributed across the quad-core processor and executed synchronously, allowing multiple simulation models that formerly required a system of several processor boards to run on a single DS1006. The processor is suitable for computing detailed, central processing unit-intensive models, such as gasoline engines with variable valve timing and diesel engines with in-cylinder pressure measurement. High-speed computation is useful for HIL simulation of electric drives with multiple tasks and short cycle times. Several DS1006 boards can be connected, and users can customize real-time performance. The same interface is used to partition models for optimum use of the processor cores and to define the communication channels for data transmission between the cores as well as between boards.
