• Geometry engine
Geometry engine supports the geometry processing that is compatible with ORCHID (MB86292).
Using the display list created by ORCHID enables drawing. **(But Floating point setup command is
deleted.)
Heavy processing of geometric operations such as coordinates conversions or clipping performed by
this device can reduce the CPU loads dramatically.
• 2D and 3D Drawing
Coral 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.)
Coral also supports 3D rendering, such as texture mapping with perspective collection and Gouraud
shading, alpha blending, and anti-aliasing for drawing smooth lines.
• Display controller
Coral 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
Can be connected to SH3 and SH4 manufactured by Hitachi, to V832 microprocessor by NEC and to
SPARClite (MB86833) by Fujitsu without external circuits.
• External memory interface
SDRAM and FCRAM can be connected.
• Optional function
Final device can be selected either geometry high-/low-speed version.
• Others
