Rather than tying security resource growth directly to the number of ports, Shared IDE enables security resources to be shared across multiple interfaces, reducing duplication without compromising standards compliance. The approach offers three primary benefits:Lower cost and area: By eliminating unnecessary duplication, Shared IDE can reduce overall hardware requirements. Shared IDE for high-performance PCIeRambus has implemented this Shared IDE approach in a production-ready architecture designed specifically for high-performance PCIe systems. The Rambus Shared IDE solution enables multiple PCIe controllers and links to use a common security infrastructure while maintaining an independent security context for each port. Shared IDE addresses this challenge by decoupling security scaling from controller scaling.
