This question was posted on the "beginners" list, but I suspect that the inhabitants of vm-dev might be better able to provide an answer.

Hi, I'm just a post silicon test engineer for a company that is developing a object oriented medium grain parallel processor on a chip. It's quite a bit like a FPGA, but the chip implements ALU state machines and table lookup logic. It has multiply / accumulate (dot product) units, datapath muxes and lots of memory. The kicker is it's a tagged architecture, with 5 bits riding shotgun on the 16 bits of data. That's 8 bits of tag and 2 ready bits for a real-world 32 bit object. I've heard talk in the office that a harvard/princeton machine demo hack implementation would be nice, but that seems really 1950's .My first thought was to build a FORTH machine, or a bunch of forth machines, But Squeak seems really attractive and it goes well with the object oriented mindset of the company and the chip. So? do you think I should burn a couple hundred hours of my own time trying to cook this up? BTW: this thing runs at 1 GHz and has 256 alu's, 64 macs, tons of registers and scratch and 2X266 Mhz 40 bit ddr2 dram interfaces with 256 Mwords of store.. AKA: Mr Jones. Just how do I implement a parallel or massivly pipeline(d) squeak machine?

Indeed - is Jecel on this list?

Jim, if you have a standard C compiler and ansi libraries you should be able to get a basic VM running fairly quickly. As an example, it only took a few days to get a vm running on a custom StrongARM machine we built at Interval Research some years ago and that included a couple of revisions of the firmware to fix bugs.
If you don't have an ansi/C system.... well it might be a bit harder. And making use of the unique features of the machine is definitely a bunch more work!
If I understand you correctly, you have a 32 bit data word with an *extra* 10 bits of tagging? Except you mention a 40bit memory system, so I must have missed something.
BTW: this thing runs at 1 GHz and has 256 alu's, 64 macs, tons of registers and scratch and 2X266 Mhz 40 bit ddr2 dram interfaces with 256 Mwords of store..
Sound fun. Does it have a TCM? That would be nice facility.
Just how do I implement a parallel or massivly pipeline(d) squeak machine?
Good question. I think the answer to that is something along the lines of <dr.evil>One *million*euros!</dr.evil> Or alternatively contact me directly and we might be able to arrange something.
