Jiang Bo, OPPO, Senior Director of Chip Products
As the first Bluetooth audio SoC chip independently developed by OPPO, Mariana®️ MariSilicon Y realizes Bluetooth wireless transmission of 192kHz/24bit lossless audio for the first time through the world's fastest 12Mbps Bluetooth speed, reaching the peak of Bluetooth sound quality; integrates a dedicated NPU unit for the first time, Mariana®️ MariSilicon Y provides advanced AI computing power up to 590 GOPS for the rapidly developing computing audio, and realizes sound separation technology on the headset side for the first time, bringing a more personalized listening experience; take the lead in applying the world's most advanced N6RF process process, Mariana®️ MariSilicon Y It can combine advanced high performance and flagship battery life experience.
The fastest in the world is ultra-high-speed Bluetooth, Bluetooth sound quality has jumped 192kHz/24bit Lossless peak
For a long time, consumers have not been able to obtain sound quality comparable to traditional wired headphones through Bluetooth headphones . Because the Bluetooth speed is insufficient, a large amount of data in high-quality audio (48kHz/24bit lossless audio or above specifications) can only be transmitted through wires and cannot be wirelessly carried through Bluetooth.
Mariana®️ MariSilicon Y has realized the world's fastest 12Mbps ultra-high-speed Bluetooth solution for the first time through innovative Bluetooth underlying hardware bandwidth design, reaching 4 times the traditional Bluetooth speed. Combined with the leading performance-leading URLC lossless codec technology, Mariana®️ MariSilicon Y is currently the only Bluetooth chip that supports 192kHz/24bit lossless audio, helping every music lover listen to the richest and most visible music details in the most convenient wireless way.
Mariana®️ MariSilicon Y supports dynamic bit rate adaptive technology and can automatically adjust the codec rate flexibly within the ultra-wide range of 80Kbps-10Mbps. Whether in shopping malls with complex signals or quiet study rooms, it always provides stable and non-study audio quality. By supporting mainstream codec technology, Mariana®️ MariSilicon Y helps users always ensure first-class sound quality experience when connecting across brands.
integrates a dedicated NPU unit for the first time, 590 GOPS The strongest AI new power supports the next generation of personalized listening
Mariana®️ MariSilicon Y is an important milestone in the audio experience entering the new AI era. Compared with the current chips that generally use traditional DSP ( digital signal processor ) units to process audio data, Mariana®️ MariSilicon Y integrates a dedicated NPU computing unit for the first time, providing the most powerful power for audio computing with 590 GOPS advanced AI computing power. Compared with the most advanced DSP units at present, Mariana®️ MariSilicon Y can provide more than 23 times the computing power and more than 16 times the computing power efficiency through high-performance NPU units, and can efficiently run advanced AI audio algorithms that were not even possible in previous DSP units.
strong enough AI computing power, allowing Mariana®️ MariSilicon Y to have the ability to understand sound for the first time, and also implement sound separation technology on the audio side for the first time, opening up the next generation of personalized audio experience.Through sound separation technology, Mariana®️ MariSilicon Y supports the characteristics of custom panoramic sound, which can intelligently identify and separate vocals and instrument groups in music, helping users to customize and control the volume and spatial position of each track such as vocals, drums, bass , etc., such as amplifying the vocals and pulling them closer to their ears, or switching the drums left and right to create a unique listening feeling that belongs to them.
Based on sound separation technology, Mariana®️ MariSilicon Y also supports the characteristics of universal panoramic sound, which can transform and upgrade traditional dual-channel music into a new effect of panoramic sound, and hand over the choice of this advanced listening experience from the production side to the user side. Traditionally, if the music is not produced in the panoramic format, users cannot experience this effect. Universal panoramic sound allows users to more flexibly match their favorite music and panoramic sound effects, achieving a more immersive auditory feeling.
Mariana®️ MariSilicon Y Enriched computing power can obtain a consistent audio experience when users use multi-terminal devices without relying on the computing power of their mobile phones. For example, universal panoramic sound and personalized panoramic sound based on sound separation technology can still achieve the same functions and effects when paired with different hardware devices such as mobile phones, computers, TVs, and tablets.
The world's most advanced N6RF RF process process, with both advanced performance and flagship battery life,
Faced with the contradiction between performance and power consumption of traditional low-power Bluetooth audio chips, Mariana®️ MariSilicon Y is the first to apply the world's most advanced N6RF RF process process, achieving a new energy efficiency performance. N6RF is the most advanced RF process manufacturing technology to date. Compared with the 16nm process currently used by mainstream RF chips, N6RF technology is second generation ahead of the market, helping to improve the energy efficiency of RF transistors by 66%, while reducing the size of RF transistors by 33%.
Through the industry-leading process, Mariana®️ MariSilicon Y achieves flagship-level battery life while achieving 192kHz/24bit lossless audio and advanced AI audio capabilities.
From the first to the second, OPPO's self-developed chip goes further
Mariana®️ MariSilicon Y is OPPO's first SoC chip solution, which is completely responsible for all functions of a Bluetooth audio device. This not only marks the first time that OPPO has opened up a new field of connected chip design and has a complete set of software and hardware capabilities for Bluetooth connection, but also means that OPPO has the first Bluetooth SoC platform design capabilities with computing + connection capabilities.
Based on the previous generation 6nm, Mariana®️ MariSilicon Y has expanded to the N6RF process process, which means that OPPO has mastered the ability to apply the advanced process process to RF systems and has expanded the design expertise of chip under advanced processes. More importantly, Mariana®️ MariSilicon Y helped OPPO expand the field of vertically integrating with self-developed chips as the central axis. On the basis of the image integration of previous generation self-developed chips, it added the integration of Bluetooth connections, laying the necessary underlying connection capabilities for the integration of everything.
