用于访问随机存取存储器RAM的方法、装置和系统
摘要：
本申请提供了一种用于访问随机存取存储器RAM的方法和装置，该方法包括：处理器通过第一线程读取所述RAM的第一地址的数据，所述第一线程为连续访问所述第一地址的多个线程中的任一线程；所述处理器在通过所述第一线程从所述第一地址读取数据之后，确定与所述第一地址对应的指示信息，所述指示信息用于指示在所述第一线程之前是否有第二线程对所述第一地址进行读改写操作；所述处理器根据所述指示信息，确定所述第一线程的待修改数据；所述处理器对所述第一线程的待修改数据进行修改，生成所述第一线程的回写数据。本申请实施例的方法和装置，能够在多个线程连续对RAM的同一地址进行读改写操作时，有利于降低数据的出错率。
摘要（英）：

The invention provides a method and a device used for accessing an RAM (Random Access Memory). The method comprises the following steps that: a processor reads the data of the first address of the RAM through a first thread, wherein the first thread is any one thread in a plurality of threads which continuously access the first address; after the processor reads data first address through the first thread, determining indication information corresponding to the first address, wherein the indication information is used for indicating whether a second thread carries out a read adaptation operation on the first thread or not; according to the indication information, determining the to-be-revised data of the first thread by the processor; and revising the to-be-revised data of the first thread by the processor, and generating the write-back data of the first thread. By use of the method and the device of the embodiment of the invention, when a plurality of threads continuously carry out the read adaptation operation on the same address of the RAM, a data error rate can be favorably lowered.
