APPARATUS AND METHOD FOR PROBABILISTIC CACHE REPLACEMENT FOR ACCELERATING ADDRESS TRANSLATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240211408 titled 'APPARATUS AND METHOD FOR PROBABILISTIC CACHE REPLACEMENT FOR ACCELERATING ADDRESS TRANSLATION

Simplified Explanation

The patent application describes a method and apparatus for probabilistic cacheline replacement to accelerate address translation in a processor. This involves a cache manager implementing a policy to reduce evictions of certain cachelines during cache fills.

• The invention involves a cache shared by multiple processor cores.
• The cache uses a set-associative structure to store page table entry (PTE) cachelines and non-PTE cachelines.
• A cache manager enforces a PTE-aware eviction policy to minimize evictions of PTE cachelines during non-PTE cacheline fills.

Key Features and Innovation

• Plurality of cores in a processor sharing a cache.
• N-way set associative cache structure for storing different types of cachelines.
• Implementation of a PTE-aware eviction policy by the cache manager.

Potential Applications

• Accelerating address translation in processors.
• Improving cache efficiency in multi-core systems.

Problems Solved

• Minimizing evictions of critical cachelines during cache operations.
• Enhancing overall performance of the processor.

Benefits

• Faster address translation.
• Reduced cache contention.
• Improved system efficiency.

Commercial Applications

• This technology can be applied in high-performance computing systems, servers, and data centers to enhance overall system performance and efficiency.

Prior Art
