Intel became a member of the CHIPS Alliance this week, an industry consortium that is working to accelerate the development of open source SoC (and SiP) for various applications. As part of its membership, Intel has also donated its advanced interface bus to the group, giving developers access to the bus, and thus the means to operate on Intel (and other) chips that will use it.
Designed for use with packet system devices (SiP), Intel AIB is a high-bandwidth, low-power, PHY standard that uses a synchronized parallel data transfer mechanism (as used by modern DRAM DRAM interfaces) . This technology is independent of manufacturing processes and packaging technology, so it can be used to connect multiple chips / chiplets using various types of packages, including EMIB from Intel, CoWoS from TSMC, or 2.5D technology from other multiple vendors.
Intel's AIB has been available to third parties royalty-free for a while, so contributing technology to the CHIPS Alliance is the next step for Intel to increase adoption. By making AIB available to a very large group of chip designers, Intel is driving the development of an ecosystem of chiplets that can then be used with CPUs, GPUs, FPGAs, and other components to build multi-matrix SiPs for special purposes.
Now that the CHIPS Alliance is controlling the specifications of the advanced interface bus, its interconnection working group will be responsible for the development of this technology, which will start operating immediately. As part of a consortium, Intel will be able to further contribute to the development of AIB. Meanwhile, Intel will serve on the CHIPS Alliance leadership board.
Zvonimir Bandic, President of the CHIPS Alliance and Senior Director of Next Generation Platform Architecture at Western Digital said the following:
“Intel's selection of the CHIPS Alliance for the AIB specification confirms the primary role affecting the organization for open source software and hardware development tools. We hope for faster adoption of AIB as an open source chiplet interface. "
