3-Diff™ Additive Update Files
Revolutionize OTA Updates

By comparing changes in the lines of code, Auto Update creates the industry’s smallest and most reliable update files.

3-Diff update files do not interfere with the execution of the existing software, enabling the update to be installed without reflashing, with no reliance on an active connection, and with zero downtime.

Constant Safe State & Seamless Rollbacks

The small nature of the update file allows for multiple update versions to be written over time on the same flash memory, enabling for instant roll-back to any version in case of an error, security incident or recalls and thus maintaining a fail-safe redundancy solution.

No Changes to Current Systems
and Processes

3-Diff algorithms are integrated into the development toolchain, automatically creating update files by the toolchain in the same file format as the original embedded ECU file (ELF, S-Rec, Intel HEX).

Using standard file formats removes the burden of adapting the testing systems, production systems and dealership maintenance systems, and removes the need for a proprietary client integration on every ECU.

Clientless – no changes to bootloader

Diff files are standard bin, Intel-Hex or S-record

No changes to current software distribution channel

Significantly smaller than bsdiff and other diff technologies

Delta update without memory reprogramming, or dual memory

Supports all ECUs – 8bit and up

Less than 3% ECU cycles

Less than 1% memory footprint
