LG Electronics, a major consumer electronics company that recently decided to build its own high-performance application processors for its smartphones and tablets, is working on at least two system-on-chips code-named Odin. The new chips are currently sampling, but it is absolutely not clear when LG formally rolls them out.
Citing media sources in South Korea that quote LG representatives, UnwiredView web-site claims that there are two Odin versions: a quad-core one (running at up to 2.20GHz per core and including an ARM Mali-T604 GPU), and an eight-core one. The latter could be paired with ARM’s latest Mali –T760 graphics cores, but given the fact that they were announced recently, it is unlikely that they will be used for chips due earlier than in late 2014.
It is unclear whether the quad-core and octa-core chips will feature homogeneous ARM cores or will take advantage of Big.Little platform that involves heterogeneous – high-performance and low-power cores. It is highly likely that LG Odin chips will feature ARM's Cortex-A50-series 64-bit cores.
Earlier this year LG Electronics licensed the next generation of ARM Cortex-A50 series of central processing unit (CPU) solutions and the next generation of ARM Mali graphics processing units (GPUs). This agreement means that LG Electronics has access to ARM’s highest-performing CPU and GPU solutions to create market-leading system-on-chips.
ARM Cortex-A50 processor series is fully compatible with ARMv8 architecture introduced this year and currently includes Cortex-A57 and A53 cores. The family features AMBA system coherency to extend to many-core coherence with ARM CoreLink cache coherent fabric components, including the CCI-400 and CCN-504. The new cores are also compatible with ARM Mali graphics processor family for GPU compute applications as well as ARM’s cryptographic acceleration. ARMv8 architecture is fully compatible with programs designed for ARMv7, which will simplify transition to 64-bit computing in the ARM world.
ARM Cortex-A57 processor core is the most advanced, highest single-thread performance ARM application processor that delivers the three times higher performance than today’s leading-edge mobile SoC with the same power consumption. The Cortex-A57 also sports extended reliability and scalability features for high-performance enterprise applications.
ARM Cortex-A53 processor core is the most efficient ARM application processor ever, delivering today’s superphone performance while using a quarter of the power, thus enabling low-cost advanced smartphones of tomorrow. The core also incorporates reliability features that enable scalable dataplane applications to maximize performance per mm2 and performance per mW. The Cortex-A53 is optimized for throughput processing for modest per thread compute applications.
