approach towards CPUs. M-SPACE allows AMD to mix and match CPU features for specific tasks.
The definition for M-SPACE is as follows:
Modular: Reconfigurable “building blocks” for design speed/agility
Scalable: Linear scaling of multi and single-thread performance
Portable: Energy-efficiency for increased mobility/portability
Accessible: Ongoing commitment to open innovation
Compatible: Backward compatibility and ease of upgrade
Efficient: Optimal on-chip and system level I/O efficiency

Things are starting to make sense

If AMD is serious about the modular approach (they've been hinting at it for a long time, and they have a couple of intriguing patents, including one that looks like a way to turn multiple cores into a single superscalar CPU), that might explain some of their recent moves.
A "variable configuration" CPU would definitely need some form of code morphing to work transparently (ex., software tries to run instruction "X", and the CPU decides, based on its modules, whether to run it on a dedicated module or morph it into multiple instructions for the "generic" module). Doing this efficiently is a lot more complex than simple micro-op decoding. Transmeta has a ton of patents in this area, and AMD's acquisition of a (small but relevant) share might mean free (or at least cheap) access to those patents.
As to the on-die PCIe, we've been waiting for it since AMD licensed the patents from RAMBUS. I was kind of hoping that some of those new pins on Socket-F were precisely for that.
There's an increasing feeling that Barcelona is just a K8 "expansion pack" to keep the fans quiet (and pay the bills), and the real "sequel" keeps getting pushed back as they decide to add new features.

AMD claimed that the K8 architecture was modular, IIRC.

Never heard that, all talk of modular CPUs was well after the K8 had been released. Any links?
