Load-store unit

In computer engineering has load-store unit is a Specialized execution unit responsible for executing all load and store instructions, Generating virtual addresses of load and store operations [1] [2] [3] and loading data from memory or Storing it back to memory from registers . [4]

The load-store unit is normally used for the purpose of memory, and the unit is independently of other processor units. [4]

Load-store units may also be used in vector processing , and in such cases the term “load-store vector” may be used. [5]

Some load-stores are also capable of executing simple fixed-point and / or integer operations.
