Abstract: The interest in AI has exploded over the past few years and the use of AI in applications is poised to increase dramatically for many years. However, AI already demands very large amounts of compute, memory, and bandwidth; how to deliver these levels is becoming a pervasive challenge in computing system design. This explosive growth has provided a huge impetus to accelerate AI workloads by employing a mix of diverse components, including CPUs, GPUs, specialized accelerators, and memories. The requirement of high bandwidth interconnectivity between different components has been a major driver for heterogeneous integration. In addition, the diminishing node-to-node returns from scaling have propelled heterogeneous integration to the forefront of technology focus. This raises several questions. How does the current state-of-the-art in heterogeneous integration meet the ever-growing demands of AI? What novel integration schemes are needed to deliver continued gains in system performance? How can emerging memories and analog technologies, which show promise for accelerating AI workloads, be effectively integrated with conventional technologies? Finally, what is the path forward to deploy heterogeneous integration as a pervasive technology in this arena? We will examine both the architecture requirements for AI as well as the heterogeneous integration methods needed to enable an upward trajectory for system performance.
