High Level Assembler - Opcodes overview, Vector Extension Set E6

The table below lists all documented opcodes in extension set E6 for IBM mainframe processors. Each opcode links to a text section with some additional info on the pertinent opcode.

Opcode Assignments.

Remark:
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 E6

Currently the E6 extension set is used for vector operations.
In the past it has also been used for instructions that were part of the ECPS:VM facility.

All instructions in this table are six bytes in length. The first byte always has a value of X'E6'. The second byte designates the exact instruction.
