Chapter 1 Introduction
The SMB-2501 is an ATX size Pentium 4 motherboard
designed for high-density Internet services, CT and
industrial automation. The motherboard uses a high
integrated core logic chipset, SIS650 chipset with a high
performance host interface for Intel Pentium 4 processor, a
high performance 2D/3D Graphic Engine, a high
performance memory controller and an AGP 4X interface.
The SiS 650 integrated a high performance 2D/3D Graphic
Engine, Video Accelerator and Advanced Hardware
Acceleration MPEGI/MPEGII Video Decoder for the Intel
Pentium 4 series based PC systems. It also integrates a high
performance 2.1GB/s DDR266 Memory controller to
sustain the bandwidth demand from the integrated GUI or
external AGP master, host processor, as well as the multi
I/O masters. In addition to integrated GUI, SiS650 also can
support external AGP slot with AGP 4X capability and Fast
Write Transactions. The SiS650 adopts the Shared Memory
Architecture, eliminating the need and thus the cost of the
frame buffer memory by organizing the frame buffer in the
system memory. The frame buffer size can be allocated
from 8MB to 64MB. The Integrated GUI features a high
performance 3D accelerator with 2 Pixel / 4 Texture, and a
128 bit 2D accelerator with 1T pipeline BITBLT engine. It
