** NEPTUNE 이란? 
지상파/위성 DMB의 오디오(BSAC/AAC+)/비디오(H.264 BL) decoding을 처리하기 위해 개발된 one chip Multimedia processor.
ㆍAudio/Video solution for terrestrial, satellite DMB application
ㆍVideo : H.264 Baseline Decoder
ㆍAudio : DSP based fully programmable decoder(BSAC/AAC/AAC+/MP3)


   NEPTUNE은 MPEG-4 part10 AVC 혹은 H.264라고 불리는 차세대 영상 코덱 표준을 지원하는 멀티미디어 프로세서이다.
   특히 이 칩은 video의 경우 H.264 baseline level1.3을 지원하고 audio는 응용 분야에 맞도록 프로그램이 가능하게 설계
   되어 한국형 지상파 DMB(Digital Multimedia Broadcasting)과 위성 DMB에 모두 적용 가능하도록 설계되었다. 이 칩은
   AAC+/AAC/MP3/BSAC과 같은 다양한 오디오 디코딩이 프로그램에 의해 가능하도록 하였고, H.264 기능은 하드웨어로
   구현하여 그 성능을 최대화 하였다. 특히 ARM CPU를 내장하여 다양한 수준의 SW 적 처리가 가능하며, 시스템 집적화에
   유리하도록 다양한 주변 장치들을 내장하였다. H.264 표준의 비디오 처리는 DMB 규격에서 요구하는 CIF 급 영상을 초당
   30frame으로 디코딩 할 수 있으며 전용 하드웨어로 설계된 IDCT, VLD, Prediction, de-blocking filter등을 이용하여
   20MHz의 낮은 주파수에서도 전체 동작이 가능하도록 설계되었다. 또한 이 칩은 각종 멀티미디어 단말기의 화면 표시에
   필요한 영상 필터링 기능, OSD(On Screen Display)기능, 영상 포맷 변환 기능, 그리고 영상 크기 변환 기능 등이 포함
   되어 있어서 추가적인 기능이 없어도 자체적인 후처리(post processing)가 가능하다. Main processor로 사용되는
   ARM CPU는 시스템 운영을 위한 OS porting 및 각종 API와 응용 프로그램들의 장착을 위해 효과적으로 사용될 수 있다.
