Latest Patents

Charney's latest patented inventions include:

1. **Prefetching using future branch path information derived from branch prediction** - This patent describes a sophisticated mechanism that assesses the usefulness of prefetching instructions during the decode cycle of instructions. By predicting which prefetching instructions are beneficial, the system ensures that useful data is efficiently prefetched for execution, while unnecessary instructions are discarded. This method employs a branch prediction mask to enhance the prediction accuracy, allowing both instructions and data to be prefetched effectively.

2. **Cache memory system for selectively storing directory information for a higher-level cache in portions of a lower-level cache** - This innovative cache memory system integrates an external cache system and optimizes the storage of directory information. It operates in dual modes: in one mode, it stores data related to directory information, and in the other, it utilizes portions of cache data arrays to store directory information correspondingly. This flexibility significantly improves cache management and data retrieval processes.
