Soyo SY-K7ADA User Manual

This 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.
