His innovative approach has led to the development of a unique patent that addresses the challenges of cache memory management.
Latest Patents
One of Jean Perraudeau's key patents is titled "Process and system for switching between an update and invalidate mode for each cache block." This patent describes a process for coherent management of exchanges between memories in an information system that consists of at least two levels of memories. The system includes a central subsystem that communicates with one or more peripheral subsystems through input-output units. The central subsystem is equipped with several processors linked to a central memory and input-output units. Each processor has an associated cache memory connected to the central memory. The patent outlines how each processor executes instructions from programs stored in its cache memory. If the necessary data is not found in the cache, it is retrieved from the central memory, and a copy is created using memory blocks of predetermined size. The management of memory exchanges is dynamically adjusted based on the usage of each block, switching between update and invalidate modes when specific thresholds of ineffectiveness are reached.
