PROCESSOR-BASED SYSTEM FOR ALLOCATING CACHE LINES TO A HIGHER-LEVEL CACHE MEMORY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18169852 titled 'PROCESSOR-BASED SYSTEM FOR ALLOCATING CACHE LINES TO A HIGHER-LEVEL CACHE MEMORY
Simplified Explanation:
This patent application describes a processor-based system that manages cache memory by determining the importance of cache lines and replacing them accordingly.
- The system identifies opportunistic cache lines and marks them as such.
- It evaluates the importance of cache lines in different levels of cache memory.
- Based on this evaluation, it replaces cache lines in higher-level cache memory with lower-level cache lines if necessary.
- The system associates opportunistic indicators with cache lines in higher-level cache memory.
Key Features and Innovation:

Original Abstract Submitted
A processor-based system for allocating a higher-level cache line in a higher-level cache memory in response to an eviction request of a lower-level cache line is disclosed. The processor-based system determines whether the cache line is opportunistic, sets an opportunistic indicator to indicate that the lower-level cache line is opportunistic, and communicates the lower-level cache line and the opportunistic indicator. The processor-based system determines, based on the opportunistic indicator of the lower-level cache line, whether a higher-level cache line of a plurality of higher-level cache lines in the higher-level cache memory has less or equal importance than the lower-level cache line. In response, the processor-based system replaces the higher-level cache line in the higher-level cache memory with the lower-level cache line and associates the opportunistic indicator with the lower-level cache line in the higher-level cache memory.
