The Arm Mali-D77 DPU is the second-generation premium Mali display processor to be built on the innovative Komeda architecture. Mali-D77 adds Virtual Reality (VR) processing functions on top of Mali-D71. It has the versatility to drive either VR head-mounted displays (HMDs) or standard large and small screen premium displays. The display processor is designed to improve the overall user experience for VR head-mounted displays by eliminating motion sickness and image artefacts, such as motion blur and screen door effect. This is made possible by enabling higher display resolutions and frames rates (up to 4K90), lowering the motion-to-photon latency and improving the image quality.
Mali-D77 is an important companion to Mali GPUs, as it limits the GPU workload through offering considerable system power savings to existing 4K solutions. Enabling powerful untethered VR devices that have better performance for a longer duration of time.
|Implementation||Dual or single Display output, compatible with all major display standards, including HDMI, MIPI, VESA, CEA-861, ITU-R.
Versatility to drive either VR Head-Mounted Displays or premium large or small screen displays.
|Compatibility||Display solution with Assertive Display 5 and MMU-600.
Optimized to work with Arm Mali GPUs and Video Processors.
|Bandwidth Reduction||AFBC1.2 support enables system-wide bandwidth reduction of up to 50%.
|Security||Content is hardware protected right to the glass. The Arm Mali-D77 comes with a TrustZone secure layer for secure payment and is compatible with Arm GlobalPlatform™ Trusted User Interface and TrustZone Media Protection.|
|Composition||Composition of up to 4 VR layers
Composition of up to 8 non-VR layers (4 can be video layers).
Mixed HDR/SDR composition.
|Scaling||Scaling on the display processor reduces CPU/GPU power consumption. The Mali-D77 DPU can scale up to four layers in parallel, or split the layer across multiple engines to save power.
High quality up-scaling (up to 64x) and down-scaling (up to 6x) in any ratio.
|VR Processing Functions||Lens Distortion Correction (LDC)
Chromatic Aberration Correction (CAC)
Asynchronous TimeWarp (ATW)
|Resolution||Optimized for 3Kp120 (4Kp90 capable) for VR Head-Mounted displays. Up to 4K @ 120 fps for standard displays. Wide colour gamut and High Dynamic Range supported.|
|Rotation||90°, 180° and 270° rotation is supported along with highly configurable cropping options.|
|Picture Quality||With color enhancements, single pixel accuracy for smooth window transitions and horizontal and vertical edge sharpening.
|Input/Output||Wide range of input and output formats supported.
