Yeah, I agree with this. I've looked at a few of the videos and they have useful content, but I'd rather have readable documentation. > 8 bitters are just a little better on power (if at all) than 32 > bitters, IIRC. Oh that's interesting, I'd figured 32 bitters have 4x as many gates toggling on each cycle. It takes more instructions to make stuff happen with an 8-bitter, but for stuff like UI's that may not matter. I've thought 16 bits is a sweet spot for small cpu's running either Forth or C. > I don't see a lot of value in running a VM on the GA144 at the same > speed and possibly more power than many MCUs. The VM seems like a reasonable approach for complex control stuff reaching into the GA144 instead of adding an external processor. Of course the GA144 makes no sense as a conventional MCU replacement. It's only for when there's other stuff you want to do with the rest of the nodes. As you know, I agree with you that finding applications for the rest of the nodes isn't so easy. > I can't see how providing a C compiler to use with a single VM running > at similar speeds to an 8 bit MCU will be any real incentive to use > the GA144 and it would be tons of work.

If you've got a reasonable (virtual) cpu target, and if you don't care about crappy code coming out, targeting a C compiler isn't that hard. I could imagine it helping with user acceptance and letting people port some of their existing code instead of writing new code. One issue making things harder for you may be that you were trying to push the chip's performance to its limits. It may be easier with programs where the nodes are mostly idle and plenty fast, and you deal with speed or space problems by spreading the workload over more nodes. > They need tools to let people deal with the real problems of using the > GA144 which seems to be the floor planning. Yeah, that calls for automated tools, and more inter-node connectivity if they make a new version of the chip.
