During OPPO INNO DAY, OPPO officially launched the first and self-developed NPU chip to be called “MariSilicon X”. As the first NPU chip designed for imaging, MariSilicon X is based on the new golden architecture concept of DSA for the future AI era. Through independent innovation of IP design and 6nm advanced manufacturing process, it brings unprecedentedly powerful real-time AI computing energy efficiency. The industry-leading Ultra HDR capability, lossless real-time RAW calculation, and RGBW Pro that maximizes the sensor’s capabilities break new standards for computing images with chip-level technology.

Jiang Bo, Senior Director of OPPO Chip Products, said: ” MariSilicon X is OPPO’s first imaging work in the next ten years. Its launch marks the first time that OPPO has achieved full-link vertical integration in the field of computing imaging. Customized computing image requirements. In the future, MariSilicon X will form the left and right brains of the mobile phone’s core computing together with the general platform, officially opening the era of “one device with two cores”.

Oppo MariSilicon X integrates the self-developed MariNeuro AI computing unit, providing the maximum effective computing power of up to 18TOPS, and the industry-leading energy efficiency performance of 11.6TOPS/W, facing OPPO’s self-developed AI algorithm, to achieve the most efficient computing acceleration and power optimization. For example, when running OPPO’s self-developed AI noise reduction algorithm, Mariana MariSilicon X can achieve a processing speed of 40fps with 4K specifications, which is 20 times the performance compared to the 2fps speed supported by the previous Find X3 Pro universal NPU.

MariSilicon X also uses an innovative two-tier storage architecture to provide strong support for the excellent energy efficiency and real-time nature of AI computing. Among them, MariSilicon X integrates an on-chip memory subsystem, which can provide a large throughput of up to trillion bits per second, ensuring that massive AI data does not need to leave the AI ​​computing unit during calculations, and avoiding internal and external data exchanges. In addition, MariSilicon X is also equipped with independent DDR bandwidth with a transmission speed of up to 8.5GB/sec, which provides independent bandwidth for each computing unit in the chip, so that the supercomputing power will not be limited by the speed of reading and writing. The addition of independent DDR bandwidth also brings a 17% increase to the total bandwidth of the mobile phone system.

MariSilicon X also integrates the self-developed MariLumi image processing unit and has achieved a breakthrough in HDR performance. The MariLumi image processing unit supports a processing bit width of up to 20bit and supports an amazing 20bit Ultra HDR, which is 4 times the HDR capability of the current flagship platform. In the real-time picture, the extreme value of the brightness contrast between the brightest and the darkest reaches 1 million to 1, which is almost the same as the real feeling of the human eye. The powerful performance of Mariana MariSilicon X helps OPPO reshape the lossless image link, and pushes the AI ​​calculation that can only be done on the back end of the traditional link to the forefront with the most original information-the RAW domain, which is the future of computational photography Development brings innovation.

MariSilicon X pioneered the integration of complex AI algorithms and 20bit HDR to the RAW domain so that AI calculations are no longer limited by the loss of information and output high-quality image data for the entire image link. Compared with traditional back-end calculations, the real-time RAW calculation of Mariana MariSilicon X can bring an 8dB improvement in image signal-to-noise ratio. After owning MariSilicon X, OPPO completed the image vertical link integration for the first time. The RGBW Pro mode is the best example. Through the dual-channel design, MariSilicon X realizes the separation of RGB and W pixels for the first time, maximizing the use of each pixel characteristic and releasing the full potential of the RGBW array. The RGBW Pro mode of Mariana MariSilicon X brings a signal-to-noise ratio improvement of 8.6dB and a resolution improvement of 1.7 times, achieving substantial image enhancement without changing the sensor size specifications. With the blessing of four cutting-edge technological breakthroughs, MariSilicon X simultaneously supports 4K+20bit RAW computing+AI+Ultra HDR with a new specification, setting a new standard for computing images, allowing Android AI video to have 4K performance for the first time.

MariSilicon X will be launched on OPPO’s high-end flagship Oppo Find X series in the first quarter of 2022.
