8599 N/B Maintenance
Features Used for Test and Performance / Thermal Monitoring:
Built-in Self Test (BIST) provides single stuck-at fault coverage of the microcode and large logic arrays, as
well as testing of the instruction cache, data cache, Translation Look aside Buffers (TLBs), and ROMs.
IEEE 1149.1 Standard Test Access Port and Boundary Scan mechanism enables testing of the Pentium 4
processor and system connections through a standard interface.
Internal performance counters can be used for performance monitoring and event counting.
Includes a new Thermal Monitor feature that allows motherboards to be cost effectively designed to
expected application power usages rather than theoretical maximums.
1.2.2 SiS M661FX Graphics/Memory Controller
The SiSM661FX chipset features a SiS Real256E GPU, an AGP-8X port, and a Shared Memory Architecture
DDR400 unified memory controller, supporting Intel Hyper Threading Technology Pentium 4 microprocessors series
with FSB 800MHZ. The integrated Real256E GPU features a high performance 3D / 2D Graphics engine, a video
accelerator, a MPEG1/II motion compensation decoder, and a video link(Muxed with AGP port) to support the TV-out
& digital flat panel. The SiSM661FX, adopting the SMA, eliminates the need and thus the cost of the frame buffer
memory by organizing the frame buffer,32MB or 64MB, in the system memory. The SiSM661FX, via the secondgeneration
1GB/s Multi-threaded I/O link, interconnects the SiS963 Media I/O that integrates one EHCI compliant
USB2.0 host controller, 2 OHCI compliant USB 1.1 host controllers, dual ATA-133 IDE controllers, AC-97 V2.2
compliant audio controller, and the 10/100M bit Ethernet MAC controller with standard MII interface. Figure 1
illustrates a Pentium 4 PC system diagrams based on SiSM661FX and SiS963 chipsets.
