Number Nine Imagine 128 Series 2 Chip
The Imagine 128 Series 2 is the second generation in the Imagine family of high performance visual processors. It is implemented in a 0.5 micron 3.3 volt CMOS gate array process. Packaged in a 352 PBGA, (Plastic Ball Grid Array), it provides increased performance and added functionality over its predecessor the Imagine 128 with reduced overall system cost.
The Imagine 128 Series 2 provides a high performance PCI 2.1 compliant interface with no additional external logic required. The Drawing Engine commands provide all of the normally required operations including: BIT BLT, Line, Triangle, Write Image, and Read Image. Software may interact with the Imagine 128 Series 2 by directly manipulating pixels through the Memory Windows interface.
The Imagine 128 Series 2 is implemented using a symmetric multi graphic processor (SMGP) architecture. This architecture allows the execution of two drawing commands simultaneously with totally independent parameters.
