AI Technical Summary
Technical Problem
In existing technologies, protecting the jump buffer from occupying buffer space is complex to implement and makes it difficult to prevent jump buffer overflow, thus affecting the memory protection effect.
Method used
By modifying the descriptor of the target cache to set it to store-once mode and then canceling this mode after instruction execution, the access permissions of the cache are controlled using the descriptor's SOM and SOS flags, thus preventing overflow.
Benefits of technology
A simple memory protection method that does not occupy cache space is implemented, which effectively prevents jump cache overflow and improves cache utilization.
