Please note that the creation of descriptions for all individual instructions is an ongoing process. As yet no such descriptions have been created for the opcodes on this page.

Vector Extension Set E7

Currently the E7 extension set is used for vector operations.
In the past it has also been used for instructions that were part of the VS1 Assist facility.

All instructions in this table are six bytes in length. The first byte always has a value of X'E7'. The second byte designates the exact instruction.

They speak in tongues and work strange magics with computers. Beware the dino! And just in case you're waiting for the final demise of these dino's: remember that dinos ruled the world for 155-million years!
