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.
Digital video capture
Digital video capture function can store digital video data such as TV in graphics memory; it can display
rendered graphics and video graphics on the same screen.
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.
