On December 27, 2023, OPPO announced the latest technological progress in the four major fields of AI, performance, communication, privacy and security at the technical communication meeting: including the first handset/hands-free dual mode satellite communication of smart phones, the first end side application of 7 billion parameter model, the first tidal framework and many other cutting-edge technologies. The new technology portfolio announced this time will fully launch the next generation flagship product, Find X7 series.
Release handset/hands-free dual-mode satellite calls, leading the evolution of satellite walkie talkies to satellite mobile phones
OPPO released the satellite antenna pattern control technology, which will realize the innovative experience of handset/hands-free dual-mode satellite communication for the next generation flagship. This technology can dynamically adjust and control the radiation pattern of the satellite antenna, make the antenna beam dynamically align with the satellite, and ensure that the user can maintain connection and communication status with the satellite in both handset and hands-free communication attitudes.
Lu Bao, an expert on terminal antenna of OPPO hardware engineering, said: "We are very happy to achieve the latest breakthrough in satellite antenna technology in the next generation flagship product for the first time through continuous research and accumulation, using a series of innovative technologies and patents. Through satellite communication technology and comprehensively upgraded antenna, smart communication and near-field communication technology, we expect users to have a reliable communication experience throughout the scene. "
The traditional satellite communication mobile phone uses a single antenna design, and cannot meet the demand for transmission power in the head to hand state. It can only support the use of a hands-free mode, which will lead to problems such as unclear communication in severe weather conditions such as strong winds. OPPO's new handset/hands-free dual-mode satellite call is the first time that mobile phone satellite call experience has evolved from "satellite walkie talkie mode" to "satellite phone mode" that conforms to users' intuition, helping users to achieve more efficient communication efficiency in extreme environments.

Zhang Jun, general manager of OPPO Software Innovation Center, said: "The big model of independent training and personality of OPPO, AndesGPT, contains multiple versions of parameters from 1 billion to 100 billion, with rich knowledge reserves, unlimited memory and good use of tools; The technical architecture of end cloud collaboration can support diversified application scenarios. With the cooperation of a variety of technologies, we will also implement a 7 billion parameter big language model and a generative visual model for the first time in the Find X7 series, which will bring a local AI experience with faster response, stronger processing capability and higher generation quality while ensuring user privacy and security. "
Thanks to the AndesGPT 7 billion parameter big language model of the complete end side application, the Find X7 series will bring the next generation AI experience of natural language understanding, text content summary, call voice summary, etc. Compared with other models on the same platform, the OPPO AndesGPT 7 billion parameter big language model can generate 20 times faster response at 200 acronyms, and 2.5 times faster response for 2000 acronyms.
At the same time, the AndesGPT of OPPO can achieve a maximum of 14000 abstract words, which is 3.5 times that of other models on the same platform. In terms of generation quality, compared with the 1 billion parameter model, AndesGPT's 7 billion parameter big language model brings more complete and accurate records of call summary ability with higher "IQ" understanding ability.
OPPO also announced AndesGPT generative visual model based on independent training, which will bring image semantic understanding, subject recognition and segmentation, image extension and generation capabilities, as well as a new functional experience of subject elimination and live scene redrawing for the Find X7 series. AndesGPT generative vision mode brings a wider range of image experience to mobile phones.
Compared with other cloud models on the same platform, which can only support human body recognition, AndesGPT not only supports the recognition and segmentation of more than 120 types of subjects, but also can achieve hair level segmentation and up to six multi-agent separation, as well as the filling and natural generation of large areas of images, which greatly expands the use range and practicability of the large generative visual model. In addition, the end application of AndesGPT generative visual model also brings about 60% shorter generation time and higher generation accuracy compared with other models on the platform, which brings users a more readily available generative visual experience.
Innovative tidal architecture, breaking the bottleneck of chip energy efficiency

Hong Hansheng, director of OPPO software technology planning and architecture design, said: "Tidal architecture is a collection of chip software hardware integration technologies developed by OPPO itself, and is a chip optimization technology created by a group of people who understand chips. In the past, from the first level cache to the system cache has always been the technical area of the chip design company. Through the tidal architecture OPPO, it has broken the boundaries of technology, mastered the use of the third level cache to the system cache, and brought a significant leap in computing efficiency to the flagship products with the chip level capabilities of no man's area and deep water area. "
Through in-depth joint research and development with chip manufacturers, OPPO has deepened the tidal architecture into the on-chip cache system that traditional mobile phone manufacturers cannot use in a refined way, and jointly designed cache partitions, the dynamic ratio of CPU/GPU, and the fast channel scheme of clean data with chip manufacturers. Through the tidal architecture, OPPO realizes dynamic matching of system level cache for the first time, and dynamically allocates system level cache resources for CPU and GPU according to computational tasks and rendering tasks in real time. Through this unique technology, the tidal architecture can achieve an average energy efficiency benefit of 8%.
In addition, the tidal architecture also supports a new scene level computing power and power analysis model in the chip, which can realize dynamic computing power and power consumption evaluation and analysis based on a single scene, and dynamically disassemble each computing task to the computing power distribution of each computing unit on the chip in real time to find the best energy efficiency combination, Achieve more competitive energy efficiency performance for diverse user applications. By precisely and dynamically scheduling the computing power of the GPU, the tidal architecture can also remarkably control the display delay, achieving an unprecedented continuous and smooth experience for the Android flagship. In the test of simulating users to launch applications 320 times a day, the standard deviation of Find X7 with tide architecture is only 11ms, which achieves a smooth performance that is more durable and stable than that of the same platform and other platforms.
