2.18 Standard PCI Bus Interface with Bus Mastering
Support
A simple Bus Interface Unit (BIU) provides a low cost, single
chip solution for IBM®
PCs or compatibles on PCI 2.1 bus
systems with Bus Mastering capability and speeds up to
66MHz. Bus Mastering gives the Video 107AGP 3D & TV
access to the PCI bus, allowing data transfer from the
video/graphic chip to other devices on the same PCI bus. For
instance, the local CCD captured data can be sent to the PCI
bus for compression and delivery to a remote site.
The 8-bit Video Module Interface (VMI) compatible interface
supports video input devices such as MPEG decoders and
television tuners. Additionally, the zero-wait state host write
buffer, read cache, and memory mapped I/O increase
operating speeds and contribute to peak performance levels.
All the I/O interfaces are 5V tolerant, capable of interfacing
with external devices operating at 5V, even though the Video
107AGP 3D & TV runs at 2.5V. Graphics system throughput
is further enhanced by a command FIFO, allowing maximum
bus transfer speed for applications such as Windows® or
AutoCAD™ that directly access video memory.
2.19 Accelerated Graphics Port Support
The Video 107AGP 3D & TV supports the Accelerated
Graphics Port, an Intel defined standard, to increase the
available bandwidth for transferring 3D texture data and DVD
video playback. The Video 107AGP 3D & TV supports
different configurations of the AGP either in a base line AGP
using PCI Bus Master Protocol or in a full blown (double
clocking) for future expansion. In AGP address queuing, the
Video 107AGP 3D & TV is able to use system memory in
sideband addressing to improve the performance in texture
mapping, alpha blending, and Z-buffering in 3D and motion
compensation in DVD video playback.
2.20 Complete Hardware Compatibility
The Video 107AGP 3D & TV is fully compliant with the PCI
2.1 Bus specifications and supports VESA™ DDC and VAFC
standards. The Video 107AGP 3D & TV is 100% IBM®
VGA
compatible on the BIOS and Drivers, allowing full
compatibility with virtually any VGA application software.
The Video 107AGP 3D & TV provides hardware support to
DirectDraw™, offering high speed game graphics on Windows
