ARM states that DynamIQ big.LITTLE configurations could feature 1+3, 2+4, 1+7, and other core configurations that we haven't seen before, which will clear the way for more specialized SoCs for the next 100 billion devices ARM expects to power by 2021. The DynamIQ microarchitecture is claimed to be the most flexible and versatile yet as it goes beyond ARM's big.LITTLE (introduced in 2011) with the ability to mix different types of cores in the same cluster.
ARM's DynamIQ architecture builds on its earlier big.LITTLE with the ability to mix up to eight cores of differing performance/power ratios, while also adding instructions created to accelerate AI and ML applications.
Chip design firm ARM has unveiled its Dynamiq technology to make better multicore processors that can handle artificial intelligence, cloud computing, and new kinds of devices. 'DynamIQ big.LITTLE carries on the "right processor for the right task" approach and enables configurations of big and LITTLE processors on a single compute cluster which were previously not possible, ' explained ARM's Nandan Nayampally at the unveiling.
DynamIQ isn't just about big-picture improvements - individual CPU cores are now a lot more capable as well. According to ARM the new architecture thus delivers "substantially more granular and optimal control" in SoC design.

Federal Reserve speakers are scheduled to comment this week which could give the market more insight into the Fed's rate path. Lower yields undermined the greenback's allure, softening the dollar to three-week lows near 112.26 yen in early Asian trade.
The interesting bit in regards to machine learning is that training usually happens in the datacenter (although one company, XNOR.ai, also maintains it will offer training on a device) while the inference, or execution, of the models happens on both the cloud and on specific device. The company said the platform will be available in the course of this year for all Cortex-A processors. But although that focus has allowed the company to crush Intel Corp. and utterly dominate the smartphone industry, its chips don't pack enough punch for newer applications like machine learning and virtual reality.
Even though phones, smart TVs, and other connected devices aren't susceptible to the blue screen of death, they have countless other hardware and firmware limitations that chip-maker ARM is trying to solve.
Taken together, ARM says that the next generation of Cortex-A processors using DynamIQ will be capable of achieving a 50x increase in AI performance over the next five years (compared to a contemporary Cortex-A73 design).
