SPECULATING OBJECT-GRANULAR KEY IDENTIFIERS FOR MEMORY SAFETY - A simplified explanation of the abstract
This abstract first appeared for US patent application 17886981 titled 'SPECULATING OBJECT-GRANULAR KEY IDENTIFIERS FOR MEMORY SAFETY
Simplified Explanation
The abstract of the patent application describes a process where a cache determines a speculated color value for a memory access request, receives a data granule of a cacheline from memory, and decrypts the data using the speculated color value.
- A processor core requests a cacheline to be loaded from memory in a memory access request.
- A cache determines a speculated color value for the memory access request.
- The cache receives a data granule of the cacheline from memory.
- The cache decrypts the data of the data granule using the speculated color value.
Potential Applications
- Improved data security in memory access requests.
- Enhanced performance in data decryption processes.
- Efficient utilization of cache memory in processor cores.
Problems Solved
- Ensuring data security during memory access requests.
- Optimizing data decryption processes.
- Enhancing cache memory functionality in processor cores.
Benefits
- Increased data security.
- Faster data decryption.
- Improved overall system performance.
Original Abstract Submitted
A processor core requests a cacheline to be loaded from a memory in a memory access request; and a cache determines a speculated color value for the memory access request, receives a data granule of the cacheline from the memory, and decrypts data of the data granule using the speculated color value.
