Hi Gil,

I think such multiprocessing, what you want, need MMU and DMA capabilities and was not supported by the 8051 core.

Typical multiprocessing in my applications was done for saving space, saving costs, easier wiring, easier and more reliable tasks. Not for higher speed.

So the micros working on different places (pcbs) and communicate over the build in UART (slow) or I2C or CAN (fast). No shared memory or other high speed technics used.
