General Description
The PMC-700-X00 Graphics Controller is based on the 3Dlabs Permedia3
graphics processor. The Permedia3 provides a virtual texture memory
management unit, a 256 Mbyte virtual texture address space, a multi-texture
unit (single-pass), an integrated 270 MHz RAMDAC, a high-speed 128-bit
memory interface, seven DMA engines, a unified 2D/3D raster core, and an
integrated SVGA controller.
The PMC-700-X00 has 64 Mbytes of SDRAM, giving 32 Mbytes of useable
graphics memory. It is compatible with both the PowerPC/VxWorks and
Pentium/WinNT platforms. Figure 1.1 illustrates the PMC-700-X00
