Yesterday, OPPO officially released the Find X7 series. As a new flagship, OPPO has brought a lot of new features and apps to the Find X7. In particular, it is worth mentioning that OPPO has also announced some progress in the research of chips.
Regarding the past of OPPO's chip, we are not going to say much here, because there have been many ** reports on this in the past. However, after the "Zheku incident" occurred at that time, it was rumored that OPPO retained a small team of chip research, although OPPO did not confirm it at that time, but this time Jiang Bo's appearance confirmed this statement. It is also the participation of people who have an in-depth understanding of the underlying chip such as Jiang Bo that promoted the birth of the "tidal architecture".
Jiang Bo, assistant president and head of chip technology at OPPO, said: "If you want to achieve the ultimate energy efficiency performance, you must really understand the underlying operation logic of the chip. It is precisely because of OPPO's deep accumulation in the field of chip technology that we can launch the revolutionary tidal architecture on the Find X7 this time. The tidal architecture can not only play a role at the macro application level, but also penetrate into more refined single-scene slices to achieve accurate scheduling of chip computing power. It is a new converged technology stack with deep customization and interlocking of software and hardware, and efficient collaboration. ”
Hong Hansheng, director of software technology planning and architecture design at OPPO, also emphasized in an interview with Lei Feng.com: "Tidal architecture is a collection of OPPO's self-developed chip software and hardware fusion technology, and it is a chip optimization technology created by a group of people who understand chips. ”
As OPPO said, in the past, from the first-level cache to the system cache has always been the technology area of the chip design company, and OPPO has broken through the boundaries of technology through the tidal architecture, mastered the use of ** cache to system cache, and brought a significant leap in computing efficiency to Find X7 with chip-level capabilities in no man's land and deep water area.
Through in-depth joint research and development with chip manufacturers, OPPO has deeply integrated the Tidal architecture into the on-chip cache system that traditional mobile phone manufacturers cannot use in detail, and has jointly designed cache partitions, dynamic CPU GPU ratios, and fast channel solutions for clean data with chip manufacturers. Through the Tidal architecture, OPPO realizes the dynamic matching of system-level cache for the first time, and dynamically allocates system-level cache resources for CPU and GPU in real time according to computing tasks and rendering tasks. With this unique technology, Tidal Architecture can achieve an average energy efficiency gain of 8%.
In addition, the Tidal architecture also supports a new scenario-level computing power and power consumption analysis model within the chip, which can realize dynamic computing power and power consumption evaluation and analysis based on a single scenario, as well as real-time dynamic disassembly of each computing task into the computing power distribution of each computing unit on the chip, find out the best combination of energy efficiency, and achieve more competitive energy efficiency performance for diverse user applications. By precisely scheduling the GPU's computing power dynamically, Tidal Architecture also provides excellent control over display latency, enabling an unprecedentedly smooth and continuous experience for Find X7.
In his speech, Jiang Bo emphasized that the complex and changeable user application scenarios and the lack of understanding of the underlying technology of the chip in the past are the two key technical challenges of chip performance tuning. For this reason, OPPO believes that if you want to achieve the ultimate energy efficiency performance, you must really understand the underlying operation logic of the chip. This time, the revolutionary tidal architecture launched in Find X7 can not only play a role at the macro application level, but also go deep into the finer single-scene slicing to achieve accurate scheduling of chip computing power, it is a new fusion technology stack of software and hardware deep customization interlocking, efficient collaboration, based on the scene performance model and the energy efficiency model of the chip IP, it can calculate the optimal solution of SOC energy efficiency under various combinations, and achieve the perfect balance of product performance, battery life, and stability.
OPPO's attempt at the underlying architecture of the chip has given people new ideas about whether OPPO will still get involved in chips. In this regard, Liu Zuohu, senior vice president of OPPO, said that OPPO does not make chips itself, but retains a professional chip technology team, the purpose of which is: to deeply customize chips with MediaTek, Qualcomm and other platform factories.
OPPO understands users better, communicates with MediaTek and Qualcomm, and can translate the understanding of users into the language of chips, which is more valuable than making chips by itself, and is more in line with the needs of target users, and this is the case with the tidal architecture of the Find X7 series. Liu Zuohu said.
Liu Zuohu also revealed a trend about mobile phones in the exchange with **. He said that at present, the cost of adding an independent security chip to the mobile phone is not too high, which has also become a new focus for chip manufacturers.
