Arm Unveils New AI Platform for Smartphones

    Arm unveiled its AI-focused CSS for Mobile 2 computing platform for smartphones on September 10. The new system allows chipmakers to build processors and graphics units on a ready-made foundation. The platform follows the Lumex Compute Subsystem solution introduced last year. Its main focus is performing artificial intelligence tasks directly on the device.    One of the key innovations is the Mali G2-Ultra NX graphics processor. It is the first Mali graphics processor with a dedicated artificial intelligence accelerator. According to Arm, this dedicated unit increases performance per watt in neural graphics by 4 times. Neural graphics refers to using artificial intelligence to enhance, reconstruct, or fully generate images.    The CSS for Mobile 2 platform also includes a processor system consisting of C2-Ultra and C2-Pro cores. The C2-Ultra delivers 15% higher performance in single-core tasks than the previous C1-Ultra. At the same performance level, power consumption can be reduced by 38%. The C2-Pro cores are designed to perform everyday tasks while consuming less power.    The processor’s 2 SME2 units perform artificial intelligence computations directly on the smartphone with low latency, without sending them to a cloud service. These units are designed for artificial intelligence systems that perform multistep tasks on the user’s behalf. The new architecture provides 2 times more computing power than the previous C1 generation and delivers a 70% speed increase for small language models. SME2 is already used on Android and iOS devices. Alipay, Google AI Edge Gallery, Oppo, and vivo have also worked on this technology.
