SYSTEM USING A UNIQUE MARKER WITH EACH SOFTWARE CODE-BLOCK
First Claim
Patent Images
1. A system comprising:
- a marker from a plurality of markers carried by a respective one of a plurality of code-blocks;
a processor configured to detect a change in the marker in an instruction stream, and configured to identify whether to notify an operating system when there is a change in the marker; and
a compiler/interpreter to determine the marker for each code-block and tag the code-block with the marker.

Abstract
A system and method for improving software maintainability, performance, and/or security by associating a unique marker to each software code-block; the system comprising of a plurality of processors, a plurality of code-blocks, and a marker associated with each code-block. The system may also include a special hardware register (code-block marker hardware register) in each processor for identifying the markers of the code-blocks executed by the processor, without changing any of the plurality of code-blocks.
