Software development kit streamlines SLAM in mobile devices

To develop simultaneous localisation and mapping (SLAM) –enabled mobile devices, augmented reality/virtual reality (AR/VR) headsets, robots, autonomous vehicles and drones, Ceva offers the SLAM software development kit for CEVA-XM intelligent vision DSPs and NeuPro AI processors

The kit incorporates hardware, software and interfaces that can “significantly lower the entry barrier” to integrate efficient SLAM implementations into low-power embedded systems, says Ceva.

According to Ilan Yona, vice president and general manager of the vision business unit at Ceva: “SLAM is the underlying technology that enables high-accuracy 3D mapping of a device’s surroundings”. He believes that the company’s expertise in designing vision DSPs and software algorithms will introduced customers to 3D machine vision design.

The Ceva-SLAM software development kit has a detailed interface from a CPU to offload the heavy lifting SLAM blocks to the Ceva-XM DSP. These building blocks use the DSP to support both fixed point and floating point math and extend the device’s battery life. They also include capabilities for image processing (including feature detection, feature descriptors, feature matching), linear algebra (including matrix manipulation, linear equation solving) and fast sparse equation solving for bundle adjustment. The software development kit can run a full SLAM tracking module on the Ceva-XM6 DSP at 60 frames per second consuming just 86mW (using a frame size of 1280 x 720, running on Ceva-XM6 using TSMC’s 16nm process).

The software development kit, deployed with a Ceva-XM DSP or a NeuPro AI processor, can be used for visual positioning, classical and neural network workloads for imaging and vision using SLAM.

The Ceva-SLAM software development kit is available for licensing now, exclusively in conjunction with the Ceva-XM intelligent vision DSPs and NeuPro AI processors.

Ceva will presenting the Ceva-SLAM software development kit at the Embedded Vision Summit in Santa Clara, California, USA (Wednesday 22 May).

Ceva licenses signal processing platforms and artificial intelligence processors.  It provides low power IP for vision, audio, communications and connectivity including   DSP-based platforms for LTE/LTE-A/5G baseband processing in handsets, infrastructure and cellular IoT (NB-IoT and Cat-M) enabled devices, imaging and computer vision for any camera-enabled device, audio/voice/speech and low power always-on/sensing applications for IoT markets.
