Ø ALi M1647 Overview

The M1647 is a high performance, high value North Bridge that supports all Athlon family processors. Internally all 128-bit architecture with optimization for S2K bus, DDR and AGP4X interface, the M1647 has outstanding high system performance under all types of system operations. The M1647 North Bridge, coupled with one of ALi’s widely adopted PCI South Bridge devices (M1535D+) provides a flexible and scalable motherboard core logic solution to fill all applications. The M1647 supports all Athlon family microprocessors. Processor bus speeds of 66MHz to 133MHz are supported. This interface has 16 entries for outstanding processor commands and system probe commands. This interface supports FID change protocol for mobile purposes. The M1647 can support up to 3.0 GB of SDRAM or DDR-SDRAM main memory. Supports any combination of 66/100/133MHz memory bus frequency and CPU bus frequency with minimized internal protocol handshaking overhead, the M1647 provides a flexible system application. In addition to dynamic memory power down, the M1647 also supports a dynamic gated clock for the internal chipset logic circuitry, which will reduce the system power consumption for mobile applications. The m1647 support the CAS-before-RAS refresh scheme and Self-refresh scheme during normal mod and suspend mode, respectively. The memory access controller plays a key role of dispatching the job to the memory interface. By using a two-level dynamic arbitration scheme, the M1647 fulfills multiple demanding sources that need access to the main memory with balanced latency and maximum throughput. Another important role of the memory access controller is the integration logic between the AGP interface and main memory to support the AGP memory address to physical memory address translate. To fulfill this function, the M1647 uses 128 entries and 16 tags to implement a one level GART (Graphic Address Re-mapping Table) scheme. The M1647 supports all features of the AGP version 2.0 specification.

Motherboard Description SY-K7ADA

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.
