INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240345966 titled 'INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD
The patent application describes an information processing device with multiple CPUs, cache memories associated with the CPUs, and a main memory. Each CPU acquires a lock to exclusively access data in the main memory before accessing the data. Data related to CPU access and lock IDs are associated and written in cache lines of the cache memories. When a CPU other than the corresponding one acquires the lock specified based on the lock ID written in the cache line, the cache line is flushed.
- The information processing device includes multiple CPUs, cache memories, and a main memory.
- Each CPU acquires a lock before accessing data in the main memory.
- Data related to CPU access and lock IDs are written in cache lines of the cache memories.
- Cache lines are flushed when a CPU other than the corresponding one acquires the lock specified based on the lock ID.
Potential Applications: - This technology can be used in multi-core processors to manage data access efficiently. - It can improve the performance of systems requiring exclusive access to shared data.
Problems Solved: - Ensures exclusive access to data in multi-CPU systems. - Prevents data corruption and conflicts in accessing shared data.
Benefits: - Enhanced data access efficiency. - Improved system performance in multi-CPU environments.
Commercial Applications: Title: "Efficient Data Access Management Technology for Multi-CPU Systems" This technology can be utilized in servers, data centers, and high-performance computing systems to optimize data access and improve overall system performance.
Questions about the technology: 1. How does this technology improve data access efficiency in multi-CPU systems? 2. What are the potential challenges in implementing this technology in real-world applications?
Original Abstract Submitted
an information processing device () includes a plurality of cpus (), a plurality of cache memories () associated with the plurality of cpus (), and a main memory (), each of the plurality of cpus () acquires a lock for exclusively accessing data in the main memory (), and then accesses the data, data related to access of a corresponding cpu () and a lock id for specifying the lock related to the access are associated and written in a cache line of each of the plurality of cache memories (), and a cache line of each of the plurality of cache memories () is flushed when a cpu () other than the corresponding cpu () acquires the lock specified based on the lock id written in the cache line.
