다음세대의 액션캠용 이미지프로세서 소식입니다.

아래에 샤오미 4K액션캠을 소개하면서 처음에 나왔던 그 암바렐라(?)사입니다.

Ambarella, Inc. (NASDAQ: AMBA), a leading developer of low-power, HD and Ultra HD video processing semiconductors, today introduced the S5 System-on-Chip (SoC) targeting professional high-quality 4K and multi-imager IP camera designs. The S5 offers advanced features including 4K multi-exposure High Dynamic Range (HDR) fusion, 360° de-warp and ultra-low light processing. Maximum performance is 4Kp120 or 8Kp30 of H.264/AVC and 4Kp60 frames of H.265/HEVC, while supporting flexible multi-streaming, rate control and transcoding functions. The S5 supports the high-quality Main10 HEVC Profile (10-bit H.265) for outstanding representation of high contrast scenes and a wide color gamut. In addition, it leverages Ambarella’s SmartHEVC™ technology to radically reduce 4Kp30 video bitrates to between 512 Kbps and 4 Mbps, minimizing network bandwidth requirements and saving on storage costs. The S5 image sensor interface and its advanced 1-Gigapixel/s Image Sensor Pipeline (ISP) can be configured as up to four independent sensor inputs to allow development of high resolution multi-imager cameras.

The S5 will play a critical role in the industry’s shift to 4K and H.265," said Fermi Wang, President and CEO of Ambarella. "With it, our partners gain a leading-edge image processor that delivers low power consumption, superior image quality, smart H.265 compression and a powerful quad-core CPU.”

The S5 includes a 1.2 GHz quad-core ARM® Cortex®-A53 64-bit CPU with floating point and NEONTM available for user applications. A Linux-based Software Development Kit (SDK) allows customers to develop highly differentiated products including 4Kp60 traffic cameras, 4x4K multi-imagers and surround view cameras, with support for advanced features including intelligent video analytics, in-camera edge storage and transcoding.

Ambarella will demonstrate the S5 at a private event during ISC West in Las Vegas, April 6-8, 2016.

- 액션캠용 이미지프로세서이면서 8K UHD용 차세대 코덱인 H265(HEVC)를 지원합니다.
- 동시에 H264도 지원됩니다. 근데 최대가 4K/120p or 8K/30p입니다. 이는 같은 말인데 최대성능이 8K는 4K의 네배이므로, 4K/30p 네개와 같은 성능입니다. 그래서 120p를 4로 나누면 30p죠... 딱 떨어집니다.
- 멀티스트리밍은 뭔지 잘 모르겠습니다.
- Sub-LVDS/SLVS-EC/MIPI/HiSPi는 모두 센서 인터페이스 종류입니다. 이런 종류를 지원한다는 정도
- 하드웨어적인 HDR모드를 이야기하는거 같습니다. 3D 노이즈 리덕션은 기본
- 전자보정인거 같습니다. 4K에서 떨방이 지원된다는거 같네요.
- 상하반전이랑.... 360도는 뭔지 모르겠네요... 아무튼 지원된다고 하는...
- 1.2GHz의 쿼드코어 ARM Cortex-A53 CPU가 부동소수점 연산장치와 같이 있답니다. Neon SIMD는 명령어 셋인데 뭔진 아직 잘 모르겠습니다.
  SIMD는 Single Instruction Multiple Data의 약자로 멀티미디어 데이터처리에 사용되는 명령어 셋입니다.
- DDR메모리를 포함해서 14nm FinFET공정으로 만들어서 4K/30p인코딩이 가능하다고 하네요. 소비전력은 1.4W 이하랍니다.

이 정도 성능이면 뭐 꼭 액션캠이 아니더라도 카메라에 써도 되겠네요... 파나 자회사인 커넥선트가 이 보다 더 뛰어나고 소비전력이 낮은 프로세서를 발표하길 기대해봅니다.(예전에 뭐하나 발표하긴 했는데....)
