Hi all,

I'm pleased to finally announce the release of an update to the
OpenRISC 1000 architecture. Dubbed OR1K version 1.0, this update
addresses several issues, both architectural and in the manual
document.

The following is a summary of the updates:

* jump/branch delay slot is now optional
* improved version tracking
* relocatable exception vector space
* correction of arithmetic overflow and carry detection
* improvements to MAC and integer multiply behaviour
* various clarifications regarding hardware and software behaviour

There's a link to download the spec document on the wiki page:
http://opencores.org/or1k/Architecture_Specification#OpenRISC_1000_architecture_1.0

Many thanks to those who participated in the discussions regarding the
spec. Not everything that was proposed got in, but there's still some
features to be added and clarifications to be made, so we'll surely
look at doing this again.

Time to update the models and software I guess. :)

Cheers

Julius
