Each time, developing the next generation of processors for the computer market, Intel and AMD architecture create a special low-power systems ( Intel Atom or AMD Jaguar) . Only recently, ARM figured out how to combine the low power and performance. This is the concept of architecture big.LITTLE. As part of a SoC-assembly creates two separate clusters: one of the most productive core, the second not very powerful, but consume little energy. When you need peak performance, powerful core work, you need a minimum consumption - the problem being transferred to a cluster of low-power cores.
Intel company, are advised to adopt this ARM experience . It would be interesting to see similar hybrids on the market x86-compatible systems. Although AMD is more likely to come to a competitor big.LITTLE before, because it will put on the ARM, announcing the models Opteron-based telephony microarchitecture. But today we'll talk about something else. Licensing ARM big.LITTLE concept officially announced the Japanese company Fujitsu Semiconductor.
According to a press release, for the development of its LSI business with Fujitsu licenses ARM technology big.LITTLE, including architecture Cortex-A15 and Cortex-A7, as the graphics core Mali-T624. It is reported that the company plans to develop processors and controllers for industrial applications. This will be the solutions to the maximum of a 2 +2 +4, which will work together dual-core Cortex-A15, dual-core Cortex-A7 and four graphics core Mali-T624. New Fujitsu solutions will create a powerful and at the same time energy-efficient platform for the management GUI and the ability to virtualize.
What is important is GPGPU-calculations. As you probably already heard, the company expects to push its ARM architecture, not only in WEB-entry-level servers, but in supercomputers. But even big.LITTLE architecture suggests a 70 -% reduction of total consumption without restrictions in peak performance.
Total ARM technology company issued 16 licenses big.LITTLE . It is expected that processors with big.little MP will begin to appear until the end of the year.
