2.3 NM2160
The NM2160 is a high performance Flat Panel Video Accelerator that integrates in one single chip, 2
Mbytes of High Speed DRAM, 24-bit true-color RAMDAC, Graphics/Video Accelerator, Dual clock
synthesizer, TV Out support, ZV(Zoomed Video) port, Z-Buffer Data Stripping, PCI Bus Mastering and a
high speed glueless 32-bit PCI 2.1 compliance interface.
By integrating the display buffer DRAM and 128-bit graphics/video accelerator, the NM2160 achieves the
leading performance in the smallest footprint available. The NM2160 has sufficient bandwidth to perform
full-screen, 30fps video acceleration of MPEG, Indeo, Cinepak, and other video playback CODECs. The
bandwidth headroom also allows the NM2160 to deliver the highest quality video playback of any
notebook graphics solution, without compromising simultaneous graphics performance.
The unique integration of the NM2160 also allows the NM2160 to consume 70% less power than
equivalent video solutions, with fewer chips and less board space.
