big.LITTLE technology

ARM® big.LITTLE™ technology is a heterogeneous processing architecture which uses two types of processor. "LITTLE" processors are designed for maximum power efficiency while "big" processors are designed to provide maximum compute performance.

The first big.LITTLE solution pairs the ARM Cortex®-A15 processor with the ARM Cortex-A7 processor, this solution is in real devices today. Further information about big.LITTLE solutions using other ARM cores is available at

High Performance
  • big cores provide ultimate responsiveness and super fast rendering of increasingly complex web content
  • big.LITTLE processing reduces the energy consumption of the CPU, enabling faster and more powerful graphics, within the same SoC power budget
  • big.LITTLE technology puts high-end tablet performance in a form factor that fits in your pocket
Longer Battery Life
  • big.LITTLE technology intelligently utilizes the most appropriate core based on the processing power needed
  • The capable yet power-efficient LITTLE cores look after common simple tasks such as texts and emails
  • The LITTLE cores are typically running up to 95% of the time, allowing the power profile of the system to resemble the lowest power devices
Key Benefits
  • Saves more than 40% SoC power consumption in common workload tasks such as web browsing
  • Increases performance by 40% in highly threaded workloads vs ARM Cortex-A15 CPU alone, by enabling the most efficient use of all available cores
  • big.LITTLE technology provides scalability of solutions from mid-range to premium mobile devices
