This blog presents a heterogeneous multicore system built with the RISC-V Host CPU and Cadence IP: Xtensa DSPs, and the Janus Network-on-Chip (NoC). While this example uses an RISC-V CPU, any other ISA with similar capabilities can also serve as the host CPU.
At CadenceLive Silicon Valley 2025, Amit Kumar, Director of Product Management and Marketing, emphasized how Cadence’s specialized DSPs and AI intellectual property (IP) cores are key to developing future automotive systems. This blog is an excerpt from that presentation. It discusses how AI-powered DSPs foster innovation in the automotive industry and how Cadence enables this modernization.
In the rapidly advancing field of artificial intelligence, two neural network architectures have become prominent: convolutional neural networks (CNNs) and transformers. Each architecture has brought significant advancements to various domains, ranging from image recognition, video surveillance to natural language processing (NLP), speech recognition and generation, multimodal AI and more. This article aims to compare their differences and respective strengths and highlight how specialized hardware like Tensilica Vision DSPs accelerates these models for real-world applications.
The automotive sector is undergoing a profound transformation, moving beyond basic detection to a comprehensive, real-time 3D understanding of both the external environment and the vehicle's interior. ToF is emerging as a pivotal technology, offering precise 3D depth and distance information essential for navigating complex environments and understanding in-cabin dynamics.
In the rapidly evolving world of audio technology, Enkl Sound Copenhagen emerges as a beacon of innovation, blending timeless Scandinavian design with the pulsating heart of cutting-edge digital sound processing. At the core of this synthesis lies the partnership with Cadence—a union that exemplifies a shared commitment to excellence in audio quality and energy-efficient design.
To ease the programming of multiple DSPs, Cadence has upgraded its flagship Xtensa LX8 Platform with symmetric multiprocessing capability. The new Xtensa Multicore LX8 Platform allows SoC designers to automatically generate a cluster of up to eight symmetric multiprocessors (SMP) with hardware cache coherency.
