Motherboard Description SY-K7ADA XP
boosts the graphic benchmarks into another era for professional graphics
usage. The M1647 design is capable of supporting 28 outstanding AGP
commands (depth of command queue=28) and buffering 64QW for AGP
master read operations.
The M1647 is fully compliant with the PCI 2.2 specification. Flexible PCI
latency control allows the M1647 to achieve improved system
performance.
The M1647 PCI host interface features a flexible PCI latency controller
that allows a system to be tuned for the best system performance possible.
The m1647 also features an enhanced PCI arbiter that implements a fair
arbitration scheme based on a PCI and time slice mechanism. In addition
to itself and the South Bridge, the M1647 can support up to six addition
PCI masters. This gives designers the ultimate in flexibility when deciding
what combination of PCI slots and on board PCI peripheral devices to use.
One of these six PCI master channel can be assigned to a higher priority
than other five PCI masters in order to fulfill the demands of some special
real time devices, e.g. 1394 isochronous transmissions, when accessing
main memory.
Dark Green Power Management functions such as Power on Suspend,
Suspend to RAM, Suspend to Disk, PCI bus CLKRUN and Dynamic
Clock Stop are all supported. The M1647 provides the most flexible power
management capability available in any chipset.
