I was just wondering if it is possible to convert a, typically one-processor, Arduino Micro-controller into a multi-processor unit by adding on some sort of shield?
Purpose being to handle simultaneous loops.
Thanks.
No.

You do not need them if you code correctly.
You can create a few Arduino boards as slave, with one Arduino board as master.
Each slave could do a specific task. Sometimes this can be useful. For example the master running a webpage, and a few slaves with sensors, receiving RF data, and so on.
It is almost always a bad idea to have a multi processor system, it is normally more trouble than it is worth.

Programming a multiprocessor system is harder than programming "simultaneous loops" on a single CPU.
With the right hardware, it becomes somewhat possible... but it will hardly be a the solution for the goal you have in mind... you will just end up with multiple cores.
Here was my take on a dual processor '328P board.
40 IO, use jumpers to connect Serial-Serial, SPI-SPI, I2C-I2C, etc.
Each chip can connect to an RS232 driver, or connect to an offboard USB/Serial module (FTDI for example). Something fun to play with, vs 2 Arduino boards side by side.

Designed a dual '1284P board also, 64 IO, but haven't ordered boards.
Some great reply's on here. Thanks to everyone.
