ARM today announced the launch of the Mali D77 display processor, an evolutionary upgrade to the D71. The new generation of IP products brings people beyond the usual expectations of display processors and offers new features, especially as new modules open up new possibilities for AR and VR use cases. Currently, display processors primarily act as synthesis engines within the SoC, which means that they receive pixel data generated by GPUs or other SoC blocks and synthesize them into a single surface, and process all the necessary calculations needed to achieve this.
Usually today's display controller is located at the end of the display pipeline in the SoC. Just before the actual physical interface block, it converts the data to HDMI or MIPI DSI signals. The Mali D77 display processor is outside the SoC and connected to the display panel. DDIC SoC. Here, ARM is committed to providing a straightforward solution and working closely with third-party vendors. The new D71-based Mali-D77 has all its predecessor features, with special emphasis on AR and VR capabilities, which are expected to greatly improve the product experience with IP.
The main features of the Mali D77 display processor include "asynchronous time warping", "lens distortion correction" and "chromatic aberration correction", which provide some new unique use cases for display processors and continue to provide further improvements to the IP baseline function, such as Multiple levels and higher resolution and frame rate to provide a better experience and most importantly avoid side effects such as dizziness caused by delayed images. Overall, the new Mali-D77 is exciting news for AR and VR, and is expected to be smart in the next few years.Mobile phoneIt is put into use, and it can achieve higher quality independent HMD, extending the ARM market beyond the typical smartphone SoC.
