Qualcomm’s new GPU architecture to improve image processing in Snapdragon

The Spectra ISP dual-imaging signal processing will breathe life to images.

By Vinod

Qualcomm’s latest graphics processing unit (GPU) and image signal processing (ISP) unit will suck less power and add visual processing technology in its Snapdragon processors.

The company said the Adreno 530 and Adreno 510, two new GPUs, based on new Qualcomm Adreno 5xx GPU architecture will be integrated with the upcoming Snapdragon 820 and Snapdragon 620/618 processors.

Adreno 530 GPU is expected to have 40% lower power consumption than its predecessor Adreno 430, and will be capable of providing 40% faster performance.

It will support 64-bit virtual addressing, and facilitate shared virtual memory (SVM) and will enable multi-threaded performance on mobile and embedded platforms. It will also support up to 4K HEVC video support.

Qualcomm is also introducing Spectra ISP dual-imaging signal processing unit, which is designed to provide superior image quality featuring 14-bit dual ISPs that will provide more natural skin tones and hybrid autofocus framework and multi-sensor fusion algorithms.

Qualcomm Technologies vice president Tim Leland said: "We’re significantly enhancing the visual processing capabilities of Snapdragon to support next-generation user experiences related to computational photography, computer vision, virtual reality and photo-realistic graphics on mobile devices, all while maximizing battery life.

"Qualcomm Spectra ISP, together with our Adreno 5xx-class GPU, brings an entirely new level of imaging to smartphones, and is designed to allow Snapdragon-powered devices to capture ultra-clear, vivid photos and videos regardless of motion and lighting conditions and display them with the colour accuracy that nature intended."
