    • The present invention relates to a system and a method of memory management of data consistency relating to a main memory (4) accessible by at least two processors (1, 2), as well as an associated multiprocessor network. The management system comprises an assembly for management of shared access of the processors to a common area (9) of the main memory, referred to as the exchanges area, at least one copy module (12, 13) intended for performing a data copy between at least one first processor comprising at least one cache memory and the exchanges area and at least one transfer module (12, 13) intended for performing a transfer of data between the exchanges area and at least one second processor. Triggering means controlled by the second processors trigger the copy modules and transfer modules when the first processors submit requests involving transfers of data between the first and second processors.
    • 本发明涉及与由至少两个处理器(1,2)可访问的主存储器(4)以及相关联的多处理器网络相关的数据一致性的存储器管理的系统和方法。 管理系统包括用于管理处理器到主存储器的公共区域(9)的组件,称为交换区域,至少一个复制模块(12,13),用于执行数据复制 至少一个第一处理器,包括至少一个高速缓冲存储器和所述交换区域以及用于在交换区域和至少一个第二处理器之间执行数据传输的至少一个传送模块(12,13)。 当第一处理器提交涉及第一和第二处理器之间的数据传送的请求时,由第二处理器控制的触发装置触发复制模块和传送模块。
