摘要： There are disclosed a method and device for performing Copy-on-Write in a processor. The processor comprises: processor cores, L1 caches each of which is logically divided into a first L1 cache and a second L1 cache, and L2 caches. The first L1 cache is used for saving new data value, and the second L1 cache for saving old data value. The method can comprise the steps of: in response to a store operation from said processor core, judging whether a corresponding cache line in said L2 cache has been modified; if it is determined a corresponding L2 cache line in said L2 cache has not been modified, copying old data value in the corresponding L2 cache line to said second L1 cache, and writing new data value to the corresponding L2 cache line; and if it is determined a corresponding L2 cache line in said L2 cache has been modified, writing new data value to the corresponding L2 cache line directly.
