Cadence Design Systems has announced the Cadence Tensilica Vision P5 DSP, its flagship high-performance vision/imaging DSP core. This imaging and vision DSP core offers up to a 13-fold performance boost, with an average of five times less energy usage on vision tasks compared to the previous generation IVP-EP imaging and video DSP.

The Tensilica Vision P5 DSP is built from the ground up for applications requiring ultra-high memory and operation parallelism to support complex vision processing at high resolution and high frame rates. As such, it is suitable for off-loading vision and imaging functions from the main CPU to increase throughput and reduce power.

End-user applications that can benefit from the DSP’s capabilities include image and video enhancement, stereo and 3D imaging, depth map processing, robotic vision, face detection and authentication, augmented reality, object tracking, object avoidance and advanced noise reduction.

The Tensilica Vision P5 DSP core includes a significantly expanded and optimised Instruction Set Architecture (ISA) targeting mobile, ADAS and IoT vision systems. The advances in the Tensilica Vision P5 DSP further improve the ease of software development and porting, with comprehensive support for integer, fixed-point and floating-point data types and an advanced toolchain with a proven, auto-vectorizing C compiler.

The software environment also features complete support of standard OpenCV and OpenVX libraries for fast, high-level migration of existing imaging/vision applications with over 800 library functions.
