The PXIe-8840 is an embedded controller for PXI systems for processor-intensive, modular instrumentation and data acquisition applications. The PXIe-8840 includes two 10/100/1000BASE-TX (Gigabit) Ethernet ports, two USB 3.0 ports and four USB 2.0 ports, as well as an integrated hard drive, serial ports and other peripheral I/O. The module is a collaboration between the two companies that combines the ease of use of labview with the performance of an ARM microprocessor. ARM is the leading supplier of 32-bit embedded Reduced instruction set (risc) processors, with more than 75% market share and more than 10 billion ARM-core devices. With the new module, engineers and scientists can create embedded applications in the labview environment and apply them to up to 260 microprocessing controllers created with ARM-licensed microprocessor ip. These microprocessors are manufactured by the world’s major semiconductor companies, such as analog devices, It is manufactured by luminary micro, nxp, freescale semiconductor, intel and texas instruments.

A microcontroller is an integrated microprocessor that includes memory, peripheral interfaces and interfaces, and a cpu on a single chip. Microcontrollers thus become a solution for embedded systems, ideal for control and interrupt drive applications that require a real-time response to incentives. From consumer products such as garmin nuvi portable navigation devices to industrial and medical applications such as biac portable muscle stimulators, ARM microcontrollers offer a wide range of applications.

labview Embedded modules for ARM microprocessors feature labview drivers that help the field program all controls of ARM microprocessors, including analog and digital i/o, under a graphical interface. The module also has the capability of desktop emulation, so that users can run programs developed for ARM microcontrollers on their desktop computers without the aid of any other hardware. Engineers and scientists can use ni multisim, interactive spice simulation and circuit analysis software to simulate the entire signal design chain of a real embedded system design simulation environment using desktop simulation.

Additional features of the labview embedded module in the ARM microprocessor include a project wizard that can automatically configure and install to help users quickly set up projects, and can simplify interrupt driver programming by setting up labview code to run when a specific hardware abort occurs, thus achieving interrupt management. In addition to the software, NI also offers a development kit with options including the mcb2370 evaluation board system with an arm 7-series nxp processor or the luminary microprocessor stellaris lm3s8962 based on a cortex-m3 processor.
