How to make use of multi-core's full potential

Keywords:multi-core  processor speed 

The number of cores in a system isn't the be-all and end-all when it comes to power; when developers switch from a single-core to a multi-core device, they can still run into limits in performance. These caps aren't just about processor speed. They could also be due to the constraints of the overall system configuration.

So instead of focusing on cores alone, developers should turn their attention to system architecture and the performance of key interfaces when gauging the quality of a new platform. That will enable them to measure the function of key interfaces and correlate those to software operations to reach what should be their end goal: unlocking the full potential of a multi-core device.

In the past, with single-core devices, processor speed was the key determinant of performance. Now—with the addition of four, six or more processing elements—measuring system performance can be trickier.
