I realized a long time ago that it is NOT useful to try to port "Arduino" to every "worthy" processor that exists
Agreed, it does not make sense to go after every "worthy" chip. On the other hand, the Propeller-2 is unique in that it will have 16 processors, each core a 32-bit device. For me, I would use separate cores for computationally expensive calculations (FFTs, filters, etc.) related to feedback control systems and one main core for the overall controller. Then I'd use other cores to handle serial communication with other devices (e.g., EMIC speed module), while not interfering/slowing the main controller. I think a multi-processor chip would make an excellent addition to the suite of Arduino products.
What also interests me is that each of the 64 I/O pins can be configured as 13-bit ADCs or DACs. I built a 6-dof IMU using the Arduino Due and 6 of the 12 ADC pins are already taken (not leaving much for IR distance sensors, photoresistors, etc.).
I'd be very interested in Arduino's opinion on this multi-processor chip.
