GPEX-RC is a highly flexible and configurable design targeted for root complex implementations in desktop, server and embedded applications. GPEX-RC is part of GDA's PCI-Express (GPEX) family of IP solutions which includes End Point (GPEX-EP) and Advanced Switching (GPEX-AS) designs.

GPEX-RC controller architecture is carefully tailored to optimize the link utilization, latency, reliability, power consumption and silicon footprint. The design offers maximum offload through the hardware logic provided for configuration, interrupt, power management, error reporting, and message handling. The solution also offers high degree of dynamic programmability through a range of registers and a peripheral interface.
