ARM big.LITTLE Technology

big.TITTLE is a technology designed by ARM. With performance and data consumption predictied to increase by eight times, a furture proofed energy efficient solution had to be found.

By using multiple processors that are developed for different energy and performance budgets, big.TITTLE provides optimum performance and maximum efficiency. The first big.LITTLT solution will pair the ARM Cortex-A15 process with ARM Cortex-A7 process (download "How IT Works" in PDF format). This will be followed by roadmap of new Cortex processors that build on big.LITTLE making it an important innovation for furture mobile devices.

Ten Things to Know About big.LITTLE:

1. Can you switch on all the cores at once?
2. Is the software similar to existing mechanisms like DVFS and SMP scheduling?
3. Can it run with Android™ today, with no changes to Android?
4. How does big.LITTLE enable higher performance?
5. How does big.LITTLE enable greater energy savings than just lowering the voltage?
6.  Are the power savings available from big.LITTLE significant at the system level?
7. Can big.LITTLE save power on high performance tasks too?
8. How much user level code needs to be changed to support big.
9. Can there be a different number of big and LITTLE cores?
10. I hear it's hard to use... how complicated is it?
