Memory Page Markings Reduce Processor Complexity in Execution Tracing

The patent segments the tracking function by separating it from the cache structure. Instead of embedding tracking bits within the cache, the system uses external memory markings in the memory hierarchy to indicate which memory regions should be traced. This segmentation eliminates the need to modify the cache structure while maintaining trace recording capability.

The tracking functionality is extracted from the cache structure and relocated to the memory system. The patent removes tracking bits from the cache and replaces them with memory page markings that serve the same purpose of identifying which data should be traced, thereby reducing processor design complexity.

The tracking function is segmented from the cache structure and implemented externally in the memory system. Memory page markings are used to indicate which regions should be traced, eliminating the need for additional tracking bits within the cache structure and reducing IC die size.

The tracking functionality is extracted from the cache and relocated to the memory subsystem. By using memory markings instead of cache-based tracking bits, the patent removes the need for additional circuitry within the processor die while maintaining trace recording capability.

The memory system automatically provides tracing information through memory page markings without requiring active intervention from the processor. The markings are set by the operating system or memory management unit based on the execution context, and the tracing logic automatically checks these markings during memory access, eliminating the need for processor performance overhead.

The patent introduces memory markings as an intermediary between the execution context and the tracing system. These markings serve as a mediator that provides tracing information without requiring direct involvement of the processor execution units, thereby avoiding performance overhead while still enabling trace size reduction.
