690 on-chip interconnects and IP cores found in Broadcom Home Networking Division
694 host-connected chipsets based on a common library of Broadcom IP cores,
695 connected via one of two on-chip backplane (hardware bus) architectures.
700 Each core on the Sonics backplane vends a 4 KiB register block, containing both
701 device-specific CSRs, and SSB-specific per-core device management
707 The IP cores used in earlier SSB-based devices were adapted for compatibility
710 cores providing per-core device management functions in place of the SSB
711 per-core management registers.
713 When BHND hardware is used as a host-connected peripheral (e.g., in a PCI Wi-Fi
714 card), the on-chip peripheral controller core is configured to operate as
716 .Bl -dash -offset indent
718 Host access to SoC address space is provided via a set of register windows
719 (e.g., a set of configurable windows into SoC address space mapped via PCI BARs)
723 These address regions may be used as a target for the on-chip DMA engine.
725 Any backplane interrupt vectors routed to the bridge core may be mapped by the
726 bridge to host interrupts (e.g., PCI INTx/MSI/MSI-X).
744 bridged chipsets, may require on-demand remapping of address windows
748 drivers that, on host-connected peripherals, must share a small set of register
751 BHND peripherals are designed to not require register window remapping
