Whatever else it is, it can't be as simple as an IDE hack, since the "getr rX,XS1_RES_TYPE_THREAD" instruction has to be in on it. I'm fantasizing that they've added more execution-unit slots so that you get *six* instructions every 8/10 nsec instead of only four, but even if it's only a crippled version of the regular quad-issue core I'm sure the point is that it's priced accordingly so you only pay for what you use and XMOS can reach more customers. It'll be a little surprising if that flies (it seems to me the economics would pull in opposite directions) but, whatever!mikronauts wrote:where threads per core < 8 some threads just appear to be disabled; and I would not be surprised at all if the limitation is based purely on the processor model number selected in the IDE perhaps enforced by checking a processor-internal fuse/rom setting.
I also hope this doesn't distract them from getting the (*@#^*% SU01A/U8A out the door for real! Last I heard was January 2013 for it to start appearing at Digikey. I, um, can't wait!
