Overview
CEVA-XM4 is the 4th generation imaging and computer vision processor IP from CEVA, designed to bring human-like vision and visual perception to embedded systems.
CEVA-XM4 solves the most critical issues for the development of energy-efficient embedded vision systems where the die size and power budget are extremely constrained, yet the algorithms require heavy processing capabilities.
CEVA-XM4 enables the three key elements of intelligent vision processing: 3D vision, Computational Photography, Visual Perception and Analytics.
With the CEVA-XM4 you can
- Run computer vision on video streams (1080p, 4K)
- Combine depth generation with vision processing (e.g. depth + augmented reality, depth + 3D scanning)
- Enable multi-app processing (e.g. gesture + face detection + emotions + eye-tracking + optional depth)
- Implement multi-frame algorithms in high resolution (e.g. super-resolution, refocus)
Benefits
- Imitating human vision and adding computational photography to embedded systems is challenging, given the typically limited space and power resources.
- To address these issues, CEVA incorporated programmable wide-vector architecture, with fixed- and floating-point processing, multiple simultaneous scalar units, and a vision-oriented low-power instruction set.
- As a result, The CEVA-XM4 outperforms the most advanced GPU cluster shipping today by 33% faster processing, while consuming 9x less energy and is 17x smaller in die size.
