MB86296 Datasheet, PDF (12/352 Pages) Fujitsu Component Limited. – PCI Graphics Controller Specification

FUJITSU LIMITED PRELIMINARY AND CONFIDENTIAL
1.2 Features
• Geometry engine
Geometry engine supports the geometry processing that is basically compatible**1 with ORCHID
(MB86292). Using the display list created by ORCHID enables drawing. Heavy processing of
geometric operations such as coordinates conversions or clipping performed by this device can
reduce the CPU loads dramatically.
**1(Floating point setup command is changed or deleted. G_BeginCont command is deleted.
GMDR0 CF&DF table mapping is changed ... etc)
• 2D and 3D Drawing
The MB86296 has a drawing function that is compatible with the CREMSON (MB86290A). It can
draw data using the display list created for CREMSON. (But internal texture RAM is deleted.)
The MB86296 also supports 3D rendering, such as texture mapping with perspective collection and
Gouraud shading, alpha blending, and anti-aliasing for drawing smooth lines.
• Digital video capture
The digital video capture function can store digital video data such as TV in graphics memory; it can
display drawn images and video images on the same screen.
• Display controller
The MB86296 has a display controller that is compatible with ORCHID.
In addition to the traditional XGA (1024 × 768 pixels) display, 4-layer overlay, left/right split display,
wrap-around scrolling, double buffers, and translucent display, function of 6-layer overlay, 4-siding
for palette are expanded.
• Host CPU interface
The MB86296 has a 32 bit, 33MHz PCI interface fully compliant to PCI version 2.1.
• External memory interface
SDRAM and FCRAM can be connected.
• Optional function
Final device can be selected from the combination of geometry high-/low-speed version and video
capture function provided/ not provided.
