PXI-8840 | Embedded controller

The PXI-8840(part number :785780-04,785780-01,785780-33,785543-01,784193-04,784193-33 and 155186B-112L) with a quad-core processor 2.6 GHz is a plug-in controller for the PXI frame. It has a maximum controller bandwidth of 132 MB/s and an on-chip L2 cache of 3 MB. It can be used in applications for measuring instruments with upgrade processing and data acquisition. The PXI 8840 controller integrates two Ethernet ports (gigabit)10/100/1000BASE-TX, two USB 3.0 ports and four USB 2.0 ports, as well as an integrated hard drive, an RS-232 serial port, an ExpressCard/34 slot and other types of peripheral I/O. The SMB connector on the NI PXI 8840 quad-core front board can be associated with any PXI backplane trigger wire. Expecting a trigger part process to keep two resources from being associated with similar trigger lines causes the trigger to be doubly driven and may damage the hardware. Quad-core processors contain four cores, or compute engines, in a single physical package. To expand the number of threads that can be handled, the NI PXI 8840 incorporates Intel Hyperthreading technology to split each of the four physical cores into two virtual cores for a total of eight virtual cores. These eight virtual cores can perform eight compute tasks, which is advantageous under multitasking conditions such as Windows 7.

The PXI-8840 embedded controller is a controller that is integrated inside an electronic device, and it is commonly used to control and manage various functions of the device. The embedded controller is usually composed of microprocessor, memory, input/output interface and other peripheral devices, which can be programmed to implement various control algorithms and functions.

The PXI-8840 embedded controller is widely used in a variety of electronic devices, such as mobile phones, tablets, smart homes, automotive electronics, industrial control, medical equipment, etc. They are characterized by small size, low power consumption, high performance, good reliability, and can realize the intelligent and automatic control of equipment.

In the design and development process of embedded controller, it is necessary to consider the co-design of hardware and software to achieve the best performance and function of the device. At the same time, factors such as safety, reliability and maintainability need to be taken into account to ensure the long-term stable operation of the equipment.
