The EOL announcement from Ubicom makes me physically ill. The SX has three features that nothing else can touch, and on which all my designs rely: 1) 75 MIPS speed, 2) ultrafast deterministic interrupts, and 3) small size.

If you need every clock cycle available, and the meanest and leanest SX assembly language code you can write provides just enough throughput, where do you go when the SX disappears? Going from an SX to a TMS320-family component would involve size, expense, power, and complexity burdens that, at the moment, seem insurmountable to me.

Is there ANY possibility that a reduced-cog Propeller can be sped up and provided with more cog memory?

The question was asked months ago whether customers would like more memory or more cogs. It seems that the consensus was more cogs. I'd like to place a vote for more speed, even if it meant fewer cogs.

What about the possibility of a small and fast 8-bit Propeller? Is there any hope for that?

Meanwhile, I'm going to cash in an insurance policy that was purchased (by my uncle) when I was born and buy SX chips. When they run out, I guess I'll retire.   :shakehead:
