As of June 223, the research and development of oppo chips has been terminated.
on may 12, 223, OPPO announced without warning that it would terminate its self-developed chip business, dissolve zheku technology (Shanghai) co., ltd. and its wholly-owned subsidiaries and branches, and terminate all labor contracts.
OPPO's self-developed chip road began in 219. In the past four years, the image NPU chip "Mariana X" developed by OPPO and manufactured by TSMC has appeared on many OPPO flagship mobile phones. At the end of 222, the Bluetooth audio chip "Mariana Y" mounted on the Bluetooth headset has also been released.
during this period, the smartphone market is getting cold. In the first quarter of 223, smartphone shipments in China dropped by 13% year-on-year, which is the fifth consecutive quarter of double-digit decline in the China market. At the same time, global smartphone shipments fell by 13% to 27 million units. This makes the OPPO whose business model depends on mobile phones suffer greatly.
compared with special chips such as image and power supply, mobile phone processors and baseband chips have higher investment, longer research and development cycle and higher risks.
oppo chip "mariana y" features:
"mariana y" is a flagship bluetooth audio SoC chip, which is deployed to the audio listening end. Generally speaking, it is a chip used in headphones, not in mobile phones.
it adopts the advanced N6RF process technology in the world, supports the Bluetooth 5.3 standard and the Bluetooth LE Audio specification, and the Bluetooth transmission rate reaches 12Mbps. It also adopts OPPO customized URLC lossless coding and decoding technology, which supports lossless audio of up to 192kHz/24bit. The computing power of NPU is 59GOPS, and that of DSP is 25GOPS.
