Sina digital news on the morning of August 18, IC design manufacturer Lianfa Technology launched a new 5g SOC Tianji 800u, which belongs to Tianji 800 series. It adopts 7 nm process and supports 5g + 5g dual card dual standby technology. Tianji 800u further refines the nano process technology of Lianfa 5g SOC product line. The CPU part adopts 8-core design, including 2 arm cortex-a76 cores with the main frequency up to 2.4GHz, and six arm cortex-a55 small cores with the main frequency of 2.0GHz. Compared with Tianji 800, Tianji 800u CPU increases the frequency of large cores and reduces the number of large cores. In terms of 5g, Tianji 800u integrates 5g modem, fully supports independent (SA) and non independent (NSA) networking in sub-6ghz band, and supports 5g + 5g dual card dual standby technology, which is also the unique technology of Tianji series 5g SOC. In addition, Tianji 800u also supports technologies such as dual vonr voice service and 5g dual carrier aggregation to ensure the stable connection of 5g network. < / P > < p > Tianji 800u supports MediaTek 5g ultrasave power saving technology, and can dynamically adjust the working mode of modem according to the network environment and data transmission conditions, so as to improve the service life of 5g network. (Su Airlines) < / P > < p > supports the hdr10 + standard. MediaTek miravision image quality engine can bring image quality beyond hdr10 +, and support multiple video HDR optimization functions. < / P > < p > supports flexible camera configurations, up to 64 megapixel cameras and four camera combinations. The integrated MediaTek independent AI processor APU and ISP provide a range of AI camera enhancements. < / P > < p > supports voice wake-up (vow) function and dual microphone noise reduction technology, which can reduce the standby power consumption of voice assistant, and can clearly hear the user’s voice in noisy environment.
