Overview
AI/ML IP refers to specialized semiconductor intellectual property blocks designed for accelerating artificial intelligence (AI) and machine learning (ML) workloads, particularly in SoCs (System-on-Chip), ASICs, and edge devices. These IP blocks include neural processing units (NPUs), tensor engines, vector processors, and AI-optimized DSPs, enabling efficient, low-power, and real-time execution of AI inference tasks.
These IPs are critical for use cases such as image recognition, voice processing, object detection, sensor fusion, NLP, and autonomous control, in everything from edge AI devices to datacenter accelerators.
