At a Glance

Picotm is a system-level transaction manager. It provides transactional semantics for low-level and operating-system functionality. It's flexible and extensible to cover exactly your requirements. Error handling and thread isolation are provided by picotm, all you have to implement is the application logic.

Picotm is implemented in plain C and is well-suited for implementing applications and firmware that is secure, reliable and thread-safe; yet easy to develop. This makes picotm well-suited for multi-threaded and fault-tolerant software.

News and Updates

  • Reverting to picotm 0.9.0

    The updated TM module in version 0.10.0 of picotm contains a significant bug in the way it handles individual transactional memory bytes. Until this problem has been resolved, I revert the download URL to picotm 0.9.0.

    I’ll provide a bug fix ASAP. Please use picotm 0.9.0 in the meantime.

    Best regards
