The LSISAS1068E interfaces with the host through the host interface
module. The host interface module contains the PCI Express interface,
system interface, IOP (ARM966) processor, timer and configuration,
DMA arbiter, PCI timer and configuration, SIO A, SIO B, UART, external
memory, I
The PCI Express interface block supports an 8-lane PCI Express
interface. This is a high bandwidth, serial interface that features
point-to-point interconnects between devices and an advanced packetized
and layered protocol architecture. The PCI Express software is backward
compatible with previous implementations of the PCI specification.
In combination with the IOP, the system interface supports the Fusion-MPT
architecture. The system interface efficiently passes messages between
the LSISAS1068E and the host interface using a high-performance,
packetized mailbox architecture. The LSISAS1068E system interface takes
advantage of PCI Express point-to-point connections, thereby allowing a
dedicated connection to each device with no sharing.
The LSISAS1068E I/O processor (IOP) controls the system interface and
manages the host side of the Fusion-MPT architecture without host
processor intervention, which frees the host processor for other tasks.
This block supports the LSISAS1068E LED and GPIO interfaces. There
are 17 LED signals. The GPIO interface contains four independent GPIO
signals. This block also supports internal timing adjustments and
power-on sense configuration options.
