CompactPCI Controllers and CompactPCI Processors

CompactPCI controllers and CompactPCI processors are rugged, high-speed computer boards and single board computers used in industrial test and measurement applications. These devices connect to buses and system components that feature CompactPCI (cPCI), a high-performance standard based upon peripheral component interconnect (PCI) technology, and PCI eXtensions for instrumentation (PXI). Unlike PCI buses, which support only four slots, CompactPCI buses support 8 slots and can be expanded by using PCI-PCI bridges. CompactPCI controllers and CompactPCI processors are used to manage network data transfers, registers, triggers, and direct memory access (DMA). They also control the interrupt requests (IRQs) that computers receive from external devices such as test and measurement equipment.
