PCIebusz
PCIebusz is a fictional computer bus concept described in discussions about the evolution of PCI Express (PCIe). It is proposed as an auxiliary bus layer intended to extend PCIe topologies and support modular peripheral subsystems in embedded, workstation, and data-center environments.
Architecturally, PCIebusz is imagined to sit alongside PCIe endpoints and host controllers, providing additional addressing, resource
Typical design goals include bridging to PCIe, sub-bus segmentation, and plug-and-play device discovery through a dedicated
Potential use cases include dense server platforms, automotive control units, and specialized accelerators where PCIe alone
