Title: Innovations of Philippe Jean-Pierre Raphalen

Introduction

Philippe Jean-Pierre Raphalen is a notable inventor based in Valbonne, France. He has made significant contributions to the field of data processing, holding a total of 13 patents. His work focuses on enhancing the efficiency and performance of data processing systems.

Latest Patents

One of his latest patents is titled "Operand size control." This invention provides a data processing system equipped with processing circuitry and a bank of 64-bit registers. The instruction decoder in this system decodes arithmetic and logical instructions that specify operations to be performed on operands stored within the registers. It is responsive to an operand size field, determining whether the operands are 64-bit or 32-bit. This innovation ensures that if a switch is made to a lower exception level, checks are performed to prevent data leakage from higher exception levels.

Another significant patent is "Data processing apparatus and method for handling performance of a cache maintenance operation." This invention features a hierarchical cache structure with first and second level caches. The data processing circuitry performs operations on data, while cache maintenance circuitry ensures that required cache maintenance is incorporated within the eviction handling operation. This advancement optimizes the performance of data processing operations.
