How Many Cycles are Needed to Verify ARM's big.LITTLE on Palladium XP?
October 30, 2012
At the recent CDNLive! India user conference, Deepak Venkatesan and Murtaza Johar representing ARM India gave a fascinating presentation called "Verifying big.LITTLE using the Palladium XP".
ARM's big.LITTLE platform contains the combination of Cortex A15 MPCores - for high performance required in compute intensive applications - with Cortex A7 MPCores, allowing low power execution of the majority of workloads. Key to big.LITTLE is the switching between the cores, which is enabled using a Cache Coherent Interconnect - the CCI-400 fabric.
Let's first look at the results of using Palladium XP.
