Not recommended for new designs. NI recommends the PXIe-8840.
The PXIe-8108 is a high-performance Intel Core 2 Duo T9400-based embedded controller for use in PXI Express and CompactPCI Express systems. With its 2.53 GHz dual-core processor, 800 MHz DDR2 memory, and 6 MB of L2 cache, the PXIe-8108 is ideal for modular instrumentation and data acquisition applications.
Dual-core processors have two cores, or computing engines, located in one physical package. Dual-core processors can simultaneously execute two computing tasks, which is advantageous in multitasking environments, such as Windows XP, where multiple applications are running simultaneously. Two applications can each access a separate processor core at the same time, which improves overall performance. Also, dual-core processors are ideal for applications with multithreading, such as LabVIEW software, which gives an application the ability to separate tasks into individual threads. A dual-core processor can simultaneously execute two of these threads.
