PXI Module, RIO Coprocessor

The NI PXI RIO Coprocessor Modules provide dedicated FPGA-based processing to accelerate real-time and data-intensive applications within PXI systems. Designed to operate alongside NI RIO and FlexRIO modules, these coprocessors offload complex computations from the host CPU, enabling deterministic performance and reduced system latency. Built on the PXI Express architecture, RIO Coprocessor modules deliver high-bandwidth data transfer and precise synchronization with other PXI instruments. Their programmable FPGA resources allow engineers to implement custom algorithms for real-time signal processing, inline data reduction, protocol handling, and hardware-timed control. NI PXI RIO Coprocessor hardware is widely used in high-channel-count test systems, RF and wireless research, hardware-in-the-loop (HIL) simulation, and advanced R&D environments. The modular PXI form factor enables scalable processing architectures that evolve with system complexity while maintaining reliability and repeatability.
