The following illustration of block diagram will show you how SBC1134
gives you a highly integrated system solution. The most up-to-date system
architecture of SBC1134 includes two main VLSI chips, 82815 GMCH
(Graphics and Memory Controller Hub) and 82801BA ICH2 (I/O Controller
Hub), to support Celeron/Pentium-III processor, SDRAM, 3D graphic
display, PCI bus interface, APM, ACPI compliant power management, USB
port, SMBus communication, and Ultra DMA/33/66/100 IDE Master. The
on-board super I/O chip, W83627HF, will support PS/2 Keyboard/Mouse,
two UARTs, FDC, Hardware Monitor, Parallel, Watch Dog Timer and
Infrared interface. Besides, two on-board LAN devices will give user more
flexibility and reliability of application in a highly-integrated environment.
The CPU socket adopts the Socket-370 type to support high availability and
reliability, and easy operation in general industry application.
The 82815 Hub provides an integration of memory controller and graphics
capability (AGP). This delivers AGP class graphics performance to PCs at
reduced cost. It dynamically allocates and de-allocates system memory for
complex 3D textures, preserving the benefits of standard AGP add-in
solutions. Its 64-bit AGTL+ based host bus interface, optimized 64-bit DRAM
interface supports two 3.3V DIMMs at the maximum bus frequency of
100/133 MHz. The 32-bit PCI bus interface supports 4 PCI masters for
external backplane support.
The 82801BA Hub employs the Accelerated Controller Hub architecture
which makes a direct connection from the graphics and memory to IDE
controllers. It supports 2-channel dedicated Ultra DMA-33/66/100 IDE
master interfaces, full Plug-and-Play compatibility, APIC (Advanced
Programmable Interrupt Controller) interface, and internal real-time clock
(RTC) to maintain time and date of a system. It also supports 2-port USB
(Universal Serial Bus feature) and PCI 2.1 Compliance operation. It fully
supports Operating System Directed Power Management via the Advanced
Configuration and Power Interface (ACPI) specification. In addition, it is also
linked via Firmware Hub Link bus to 82802AB Firmware Hub to support
BIOS read/write access. Through the PCI bus, PC87200 PCI-to-ISA bridge is
built in as a highly integrated PCI-to-ISA bridge solution for the best
industry application.
