Re: [Gems-users] GEMS and in-order processor

[Dan Gibson <degibson@xxxxxxxx>]

Opal is an out-of-order processor model. There is little point in using Opal if you don't want out-of-order. I am unsure as to whether Opal can be configured to model an in-order core.

Dan

No I mean if I have an in-order processor model, can I use it with
Ruby. I want to have both Ruby and Opal but the processor is in-order.
Is it possible?
