ARM’s big.LITTLE CPU configurations have been around for years and the standard practice so far has been to have as many – or more – little cores as there are big cores. This is now changing with the introduction of ARM’s new designs. The high-power Cortex-X4, middle Cortex-A720 and small Cortex-A520 were unveiled today and will work in tandem to balance between performance and efficiency. ARM also introduced the DSU-120, which is what drives the DynamIQ Shared Unit system that allows different CPU cores to work together. With the DSU-120, chipset makers can build designs with up...
