Texturing System
Texture mapping capability on the Z10-T is provided by built-in texture memory. The Z13,
Z25, and V25 provide texture memory by adding two dual inline memory module (DIMM)
sockets. Both DIMM sockets must be populated with the same density DIMM. A slide-out
cover on the Z25 and V25 provides easy access to the texture memory sockets.

Geometry Accelerator Support
Geometry acceleration for lighting and transformation operations for Z13, Z25, and V25 is
provided by the optional Geometry Accelerator board. It uses six digital signal processors
(DSPs) to offload the host CPU(s) and provide for higher benchmark and application
performance. The Geometry Accelerator board sends data to the graphics board set via a
dedicated Vertex data bus, which has the following features:
