13. ❖ Power Saving & Thermal Control
► Make invisible & necessary trade-off
► Control heat generation nearing the threshold of eMMC and RAM
to avoid entering overheat state.
► Power off the hardware when reaching the threshold of
LCD/RAM/CPU to avoid destroy hardware.
► Disable data writing to eMMC in overheating state to avoid
destroying data in eMMC and application crashing.
► Use RAMFS instead of eMMC to read/write backup data in
overheating state.
► Policy-based Dynamic Rendering
❖ Data Integrity Enhancement
► All data to be stored or changed are listed in a table
► Data is stored in different place due to different requirement such
as frequency of change, hold in different cases.
► Each item is carefully designed for storage position and timing of
store.
► Limit data writing time & amount
► All data is verified with checksum on loading, backup value used
as fallback
► 4-Level backup mechanism
► Extending lifetime of NAND Memory
