The MediaTek MT8791T (see Figure 1-1) integrates Bluetooth, FM, WLAN, and GPS modules and is a highly integrated baseband platform that includes a modem and application processing subsystem to support LTE/5G/NR and C2K tablet applications. The chip integrates two Arm®Cortex-A78 cores running at up to 2.6 GHz, six Arm®Cortex-A55 cores running at up to 2.0 GHz, and a powerful multi-standard video codec. In addition, an extensive set of interfaces and connectivity peripherals for connecting cameras, touchscreen displays, and UFS/MMC/SD cards are included. The MT8791T applications processor is a multi-core Arm® Cortex-A78, and the Arm® Cortex-A55 with NEON engine provides the processing power needed to support the latest OpenOS and its demanding applications such as web browsing, email, GPS navigation, and gaming. All content can be viewed on a high-resolution touchscreen display, enhanced with 2D and 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, multiple decoders and encoders. The combination of high-performance CPU, DSP, and hardware coprocessor provides a powerful modem subsystem capable of supporting NR Sub6, LTE Cat 18, Category 24 HSDPA downlink, and Category 7 HSUPA uplink data rates, as well as Class 12 GPRS, EDGE. MT8791T hardware also embodies Wireless Communication devices, including WLAN, Bluetooth, and GPS. MT8791T hardware integrates four advanced radio technologies into a single chip, providing the industry's best and most convenient connectivity solution. Simultaneous transmission of voice, data, and audio/video on mobile phones and media tablets enables enhanced overall quality. The small size and low power consumption greatly reduce PCB layout resources.
