In a PCI Express (PCIe) system, a root complex device connects the CPU and memory subsystem to the PCI Express switch fabric composed of one or more PCIe or PCI devices. A root complex is sometimes referred to PCI root bridge. [2] The root complex generates transaction requests on behalf of the CPU, which is interconnected through a local bus ...
The CXL transaction layer is composed of three dynamically multiplexed (they change according to demand) sub-protocols on a single link: [36] [37] [24] CXL.io – based on PCIe 5.0 (and PCIe 6.0 after CXL 3.0) with a few enhancements, it provides configuration, link initialization and management, device discovery and enumeration, interrupts ...
The card must act as a PCI target, and optionally may act as a PCI master. (AGP 2.0 added a "fast writes" extension which allows PCI writes from the motherboard to the card to transfer data at higher speed.) After the card is initialized using PCI transactions, AGP transactions are permitted.
