The Imagine 128 Series 2 (I128S2) is a 128-bit graphics controller with
accelerated 2D and 3D patterned lines and shaded triangles, Z buffer, and
3D volume clipping. It provides a high performance PCI 2.1 compliant
interface with no additional external logic required.
The I128S2 is implemented using a Symmetric Multi-Graphic Processor
(SMGP) architecture. This architecture allows the execution of two
drawing commands simultaneously with totally independent parameters.
The Drawing Engine commands provide all of the normally required
operations including: BitBLT, Line, Triangle, Write Image, and Read
Image. Software may interact with the I128S2 by directly manipulating
pixels through the Memory Windows interface. A secondary Copy
Engine can be used to independently move pixmaps from one memory
area to another.
The I128S2 is implemented in a 0.5 micron 3.3 volt CMOS gate array
process and is packaged in a 352 PBGA, (Plastic Ball Grid Array).
