The '''Extended Instruction Set''' is an extension to the basic [[PDP-11]] [[PDP-11 architecture|instruction set]]; it includes hardware multiply and divide, and also multi-bit shifts. The exact instructions include in the EIS are:

* MUL
* DIV
* ASH
* ASHC

It was not available on the earliest PDP-11 models (the [[PDP-11/20]] and the [[PDP-11/05]]); it was available as an option for the [[PDP-11/40]] and the [[PDP-11/03]]; it was standard on all other PDP-11 models.
