PCI BUS
The CN8236 supports limited bandwidth SAR-shared memory segmentation and
reassembly. Any peer can use the local processor port instead of the PCI bus for
data traffic, control, and status. Hosts can use SAR-shared memory for control
and status, but transfer data across the PCI bus. This out-of-band. control
configuration diverts control overhead from the PCI bus, lessening the burden of
ATM’s high throughput and robust management requirements on the host system.
