SCALEXIO Processing Unit是什么?
SCALEXIO Processing Unit是SCALEXIO系统的计算内核。它包括一个实时操作系统,用于计算复杂的计算密集型实时仿真模型。SCALEXIO Processing Unit用于与SCALEXIO系统的I/O板卡通信,以及与多处理器系统中的其他实时处理器通信。
应用领域
- 硬件在环仿真
- 要求每个内核都具有强大计算性能的应用
- 超大型仿真模型的并行计算
变体和技术细节
For the SCALEXIO Processing unit there are two versions available
- High core performance (HCP), e.g., for handling of the large data volumes in modern bus communication, such as Ethernet or FlexRay
- High parallel performance (HPP), e.g., for parallel execution of complex and computationally intensive simulation models.
Both lines use a dedicated core for system services to minimizes negative effects on the real-time performance and are ideal suited for observation of a large number of signals.

SCALEXIO Hypervisor Extension
SCALEXIO Hypervisor Extension以基于内核的虚拟机(KVM)为基础。它使用标准Linux发行版同时运行SCALEXIO实时操作系统和虚拟机。因此您能够将Linux实时和非实时应用程序集成到SCALEXIO Processing Unit环境中,并支持低延迟、高带宽的数据交换。SCALEXIO Hypervisor Extension是一种扩展工具,是集成基于Linux的建模和仿真工具的理想之选,其能够复用现有模型,例如在早期开发阶段开发的Functional Mock-up Unit。虚拟化节省了硬件安装空间并降低了硬件维护成本,因为不需要额外的外部PC硬件。
