Alphawave Semi, a global leader in high-speed connectivity and compute silicon, has announced a strategic partnership with South Korean AI chip company Rebellions Inc. Rebellions has selected Alphawave’s multiprotocol I/O Connectivity Chiplets for its next-generation product, REBEL. This collaboration is designed to support Rebellions in delivering exceptional bandwidth for its chiplet-based compute accelerator SoC, catering to the needs of Generative AI workloads in AI and hyperscale data centres.
The partnership will allow Rebellions to leverage Alphawave Semi’s industry-leading connectivity solutions and its expertise in interoperable connectivity IP, custom silicon design, and chiplets. This collaboration aims to accelerate the development process, enabling Rebellions to bring its products to market more quickly.
Alphawave’s advanced I/O chiplet integrates multiple subsystems, including PCIe 6.0, CXL 3.1, and Ethernet, along with UCIe 2.0 die-to-die connectivity. This results in a versatile solution for Network Processing Unit (NPU) connectivity, providing Rebellions with an efficient and low-risk development path. The technology’s proven functionality and performance are set to support rapid deployment in hyperscale data centres.
The REBEL series, which includes REBEL-I/O, will utilise Alphawave’s UCIe subsystem to enhance I/O connectivity with the latest Ethernet and PCIe standards. This will improve high-density, power-efficient die-to-die communication, further advancing the capabilities of Rebellions’ chiplet-based derivatives.
Jinwook Oh, Rebellions’ CTO, praised Alphawave Semi’s leadership in chiplet-based designs, highlighting their ability to provide scalable, AI-optimised solutions. He noted the importance of Alphawave’s expertise in both high-speed connectivity and chiplet architectures, which has played a key role in their decision to collaborate. The integration of a chiplet and I/O die architecture positions Rebellions at the forefront of chiplet-based innovation.
Alphawave Semi’s SVP and GM, Mohit Gupta, emphasised Rebellions’ commitment to pushing the boundaries of performance. He noted that by adopting a chiplet approach, Rebellions is not only speeding up development timelines but also ensuring the flexibility needed to address the evolving demands of AI workloads.
Rebellions also announced that its REBEL product will be deployed as modular building blocks, scalable from individual cards to full racks. The company claims that its chiplets demonstrate significant improvements in energy efficiency when running prominent AI models, surpassing current solutions.
In June 2024, Alphawave Semi made headlines with the tape-out of AlphaCHIP1600-IO, the first multi-protocol I/O chiplet to combine PCIe, CXL, Ethernet, and UCIe on a single chiplet.
