  1. 2012.05.22 nvidia ion cuda core와 h.264 library
2개의 mp를 내장하고 있는데
음. H.264 인코딩/디코딩 라이브러리 제한이 몇개부터드라...

scalar processor는 cuda core인데 1개의 mp에 8개 있고, 4개의 mp가 32 scalar 프로세서이니 
h.264 인코딩은 ion에서는 불가능 할 것으로 보인다

MPEG-2/VC-1 support 
 Decode Acceleration for G8x, G9x (Requires Compute 1.1 or higher) 
 Full Bitstream Decode for MCP79, MCP89, G98, GT2xx, GF1xx 
MPEG-2 CUDA accelerated decode with a GPUs with 8+ SMs (64 CUDA cores).  (Windows) 
 Supports HD (1080i/p) playback including Bluray content 
 R185+ (Windows), R260+ (Linux) 
H.264/AVCHD support 
 Baseline, Main, and High Profile, up to Level 4.1  
 Full Bitstream Decoding in hardware including HD (1080i/p) Bluray content 
 Supports B-Frames, bitrates up to 45 mbps 
 Available on NVIDIA GPUs:  G8x, G9x, MCP79, MCP89, G98, GT2xx, GF1xx 
 R185+ (Windows), R260+ (Linux)
