Oppo joins the ranks of companies making their own chips with the MariSilicon X

Oppo has unveiled its first in-house image processor, which will be used to enhance imaging performance in its handsets.

The in-house developed Neural Processing Unit (NPU) is called MariSilicon X. Built on 6nm process technology, it supports 20-bit, 120db dynamic range in images, real-time RAW processing in 4K videos.

Using the NPU and Oppo’s in-house developed AI algorithms, it can apply different algorithms for noise reduction, better colour reproduction, HDR, improved detail, dynamic range, etc., and enhance imaging in the areas like autofocus, low-light performance, white balance, exposure, and so on.

MariSilicon X’s NPU delivers 18 trillion operations per second (TOPS) but is power efficient enough to deliver TOPs per watt of 11.6 to ensure performance without draining the battery.

The NPU also features a dedicated tera-bps memory subsystem, which allows MariSilicon X to make full use of the NPU’s computing power without being restricted by memory throughout, significantly reducing the time needed to copy data back and forth between storage and processing units.

MariSilicon X has a dedicated DDR with extra bandwidth of up to 8.5 GB/s. Its multi-tier memory architecture greatly minimises delays and reduces power consumption caused by unnecessary repeated read-write cycles.

Compared with the Find X3 Pro, the company's current flagship device, Oppo said the MariSilicon X will enable that phone's successors to take photos with four times greater dynamic range, produce clearer videos in dark environments, and process images 20 times faster.

The first phones to feature the new chip will be Oppo's Find X series handsets, which are slated to launch in the first quarter of 2022.
