 VRender™
3D는 32bit CPU, 3D 그래픽프로세서, 64 Poly wavetable, 이미지 프로세서 및 관련 인터페이스
회로들을 통합한 SoC솔루션으로 2D/ 3D 퍼스널 네비게이션 시스템, 휴대용 3D 게임기, 소형 컬러LCD가전, 동영상
광고 단말기, 디지털 액자 등 3D 그래픽과 디스플레이기능과 관련한 응용기기에 적합합니다.
VRender™ 3D는 하드웨어 코어내장으로 우수한 3D그래픽 성능과 저전력 소비에서 강점을 갖고 있습니다. 매직아이가
독자적으로 개발한 3D 그래픽 엔진은 동일한 그래픽 성능구현을 위해 기가급 CPU가 필요할 정도로 처리속도가 빠르며,
대부분의 3D 그래픽칩은 Floating Point CPU와 높은 소비전력을 요구하는데 반해 VRender™ 3D는
별도의 Floating Point 벡터연산기를 내장하고 있기때문에 Fixed Point CPU 와 저전력으로도 고성능의
3D 그래픽 기능을 수행합니다.
