Rmw read modify write

WebRMW means "Read - Modify - Write". Typically this is in the context of the computer architecture that the RWM operation is designed in such way that it is an atomic sequence.

WebAny instruction that specifies a file register as part of the instruction performs a Read-Modify-Write (RMW) operation. The register is read, the data is modified, and the result is stored according to either the Working (W) register, or the originating file register, depending on the state of the destination designator ‘d’ (see Table 1 for more information).
