1. System overview

The MediaTek i1200/MT8395 device (see Figure 1-1) is a highly integrated platform that includes an application processing subsystem and an AI accelerator (AIA) application. The chip integrates four ARM® Cortex-A78 cores operating up to 2.2 GHz, four ARM® Cortex-A55 cores operating up to 2.0 GHz, and a powerful multi-standard video codec. In addition, interface cameras, touchscreen displays, and UFS/SD cards contain a large number of interfaces and connected peripherals.

The application processors are multi-core ARM® Cortex-A78, ARM® Cortex-A55 with NEON engine, which provide the processing power needed to support the latest OpenOS and its demanding applications such as smart appliances, industrial IoT, and other AI-embedded devices.

All of this is viewed on a high-resolution touchscreen display and enhanced with 3D graphics acceleration.

Multi-standard video accelerators and advanced audio subsystems are also integrated to provide advanced multimedia applications and services, such as streaming audio and video, a large number of decoders and encoders.

The overall quality of simultaneous voice, data, and audio/video transmission on AI-embedded devices has been improved.
