MECHANISM TO IDENTIFY KEY SECTIONS OF IO PACKETS AND ITS USE FOR EFFICIENT IO CACHING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17988626 titled 'MECHANISM TO IDENTIFY KEY SECTIONS OF IO PACKETS AND ITS USE FOR EFFICIENT IO CACHING

Simplified Explanation

The patent application describes mechanisms for identifying key sections of input-output (IO) packets to improve IO caching efficiency. Data received from an IO device is logically partitioned into cache lines, and embedded logic on the processor is used to identify important cache lines using a cache importance pattern. Important cache lines are written to a cache, while unimportant cache lines are written to memory or a higher-level cache.

• Efficient IO caching mechanism based on cache importance patterns
• Logical partitioning of data into cache lines for improved caching
• Embedded logic on the processor to identify important cache lines
• Differentiation between important and unimportant cache lines for optimized storage
• Software programmability for cache importance patterns for various data types or transaction types

Potential Applications

The technology can be applied in various fields such as:

• Data centers
• Network infrastructure
• High-performance computing
• Cloud computing

Original Abstract Submitted

Mechanisms to identify key sections of input-output (IO) packets and use for efficient IO caching and associated apparatus and methods. Data, such as packets, are received from an IO device coupled to an IO port on a processor including a cache domain including multiple caches, such as L1/L2 and L3 or Last Level Cache (LLC). The data are logically partitioned into cache lines and embedded logic on the processor is used to identify one or more important cache lines using a cache importance pattern. Cache lines that are identified as important are written to a cache or a first cache level, while unimportant cache lines are written to memory or a second cache level that is higher than the first cache level. Software running on one or more processor cores may be used to program cache importance patterns for one or more data types or transaction types.
