Matrox 4Sight motherboard block diagram
The Matrox 4Sight EBX motherboard integrates processing,
display, storage, networking, IEEE 1394 capability, and I/O.
EBX is a standard form factor (8” x 5¾”) with a small footprint.
Processing
The Matrox 4Sight motherboard uses a National
Semiconductor
®
Geode
™
GXLV x86-compatible processor. The
processor includes a CPU, memory controller, display
controller, and PCI controller. The processor runs at 266 MHz
with a 64-bit external memory interface operating at 76 MHz.
The processor’s companion chip provides support for
non-destructive overlay, stereo audio, and IDE connection.
External memory External memory is provided via a 168-pin DIMM slot which
supports 32, 64 (default), and 128 Mbyte SDRAM modules. This
memory is shared between the CPU and display controller.
