MB86292
s FUNCTION BLOCKS
• Host Interface
This block allows the MB86292 to be connected to the SH3 or SH4 microprocessor from Hitachi Ltd., the V83x
microprocessor from NEC, or to the SPARCLite from Fujitsu without any external circuit in between. The block
provides an interface to transfer display list and texture pattern data directly from main memory to this device’s
graphics memory or internal register using the external DMA controller.
• External Memory Controller
This block connects external SDRAM or FCRAM. The data bus can be selected between 64 bits and 32 bits
and the maximum operating frequency is 100 MHz.
• Display Controller
This block contains a three-channel, eight-bit D/A converter to output analog RGB signals. The block has eight-
bit RGB digital video outputs, allowing an external digital video encoder to be connected. The block supports
resolutions of up to XGA (1024×768 pixels), enabling flexible setting.
• Set-up Engine
The on-chip geometry engine executes mathematical operations required for graphics processing precisely using
the fronting-point format. The geometry engine executes the required geometry processes selected depending
on the drawing mode and primitive type settings up to the final drawing process.
• 2D/3D Rendering Engine
This block draws images in two or three dimensions.
2D drawing
The block provides the anti-aliasing and alpha blending functions to display high-quality images even on a low-
resolution LCD.
3D drawing
The block provides true 3D drawing functions such as perspective texture mapping and Gouraud shading.
