Chip families information

Hardware structuring (courtesy of OpenHisiIpCam project):

If you know about newer versions of full datasheets or can share them for different camera types don't hesitate to make a PR.

SDKs

HiSilicon

HiSilicon SDK naming principles:

Hi35xxVxxxRxxxCxxSPCxxy

Each field is explained as follows:

• Hi35xx, segment contains chip type
• Vxxx segment contains the type of chip version
• Rxxx segment contains the release package type:
  • R001: Linux SDK
  • R002: Huawei LiteOS SDK
  • R003: Linux RDK reference design
  • other R bit is not used
• Cxx segment contains compiler specific environment
  • C00: FPGA-based
  • C01: type A compiler (e.g. uclibc based sysroot)
  • C02: type B compiler (e.g. glibc based sysroot)
  • C03 and C04 are reserved
  • C05: Huawei LiteOS
  • C09: based on Demo version
• SPCxxy segment shows current version
  • xx for each next release will be incremented by 1 (releases with fixed errors, additional features, etc)
  • xx0 indicates normal version, for temporary versions last character could be incremented by 1 in range from 1-9 and A-z.
