Rebellions, a designer of AI inference accelerators from South Korea, recently detailed its multi-chiplet Rebel 100 AI accelerator that relies on Unified Chiplet Interconnect Express (UCIe) technology at the International Solid-State Semiconductor Conference (ISSCC). The processor is one of the industry's first multi-chiplet designs to rely on UCIe-A interconnects to stitch four chiplets together.
Multi-chiplet designs are the future of high-performance AI and HPC accelerators, now that demand for performance far outpaces the ability of foundries to scale their process technologies. Large developers of CPUs and GPUs like AMD, Intel, and Nvidia have recognized the value of multi-chiplet designs and their latest products fully embrace the methodology.
