We introduce Mira, a novel display processor targeted at the AR/VR application spectrum employing mobile and head-mounted display (HMD) SoCs. Mira implements AR/VR processing functions such as asynchronous timewarp, homography and optical distortion corrections in a single-pass display composition engine. When compared with existing AR/VR systems, where this processing is done on the GPU, our dedicated processor provides a significant reduction in system memory bandwidth and system power, lower motion-to-photon latency, better image quality, as well as enables higher resolutions and frame rates that are not possible in GPU-based systems.
