GPEX-HY is part of GDA's PCIExpress (GPEX) family of IP solutions, which includes End Point (GPEX-EP), Root Complex (GPEX-RC), Hybrid (GPEX-HY), Switch port Controller (GPEX-SW), Switch (GPEX-SWITCH) and Advanced Switching (GPEX-AS) designs. GPEX-HY allows an implementation to be either in EP or RC mode.
The controller's simple, configurable and layered architecture is independent of application logic, PHY designs, implementation tools and, most importantly, the target technology. GDA solution allows the licensees to easily migrate among FPGA, Gate array and Standard cell technologies optimally. Its flexible backend interface makes it easy to be integrated into wide range of applications. |
