What makes smartphones smart, and what are the key enablers to make them smarter? The answer rests in understanding how core hardware and software components of these devices serve the use cases and the business models. We have chosen and article that looks at the hardware specification of an applications processor. Particularly the article introduces a 32 nm application processor designed for high-performance smartphones and discusses its design targets and options. To meet unprecedented levels of performance and data throughput demands, this processor employs a 200 MHz-1.6 GHz quad-core CPU, a quad-core GPU, a 2-port interleaving DRAM controller, dedicated video/audio/image processors, a camera/ display controller, and a hierarchical bus. The processor does it in a given power budget and battery life, and also in a given thermal budget by combining 32 nm high-k metal gate process technology with system-level power management techniques and dynamic thermal management techniques.
