In computer engineering, a load–store unit (LSU) 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 usually includes a queue which acts as a waiting area for memory instructions, and the unit itself operates 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–store units are also capable of executing simple fixed-point and/or integer operations.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
