Title: Tai-Lin Chang and His Patent on Program Context Switching.

Introduction

Tai-Lin Chang is an inventor associated with San Jose, California, and International Business Machines Corporation. His patent work addresses how a programmed machine responds to interruptions and manages competing operational contexts.

Latest Patents

Chang is credited with 1 patent: “Interruption Systems for Externally Changing a Context of Program.” The invention concerns programmed machines, such as peripheral controllers, that execute operations in multiple contexts. Interruption signals can activate corresponding contexts, which remain active until program execution quiesces them. During each machine cycle, the system compares active contexts and stored interruption signals to identify the highest-priority context. It then compares that context’s priority with the current context to determine whether the machine should switch contexts.

Career Highlights

Chang’s listed patent reflects work on interruption handling and priority-based control in programmed machines. The approach provides a method for deciding when an active context should take precedence over the context currently executing.

Collaborations

Chang’s listed coworkers include Paul W. Hunter and Donald J. Lang. The patent is associated with International Business Machines Corporation.

Conclusion

Tai-Lin Chang’s patent describes a priority-based system for managing interruptions and changing program contexts in a programmed machine.
