Intel contributes Advanced Interface Bus to open source consortium
Intel is contributing its Advanced Interface Bus (AIB) – a die-to-die PHY-level standard that enables a modular approach to system design with a library of chiplet intellectual property (IP) blocks – to CHIPS Alliance to foster broad adoption. Hosted by the Linux Foundation, CHIPS Alliance is intended to foster a collaborative environment to accelerate the creation and deployment of open SoCs, peripherals, and software tools for use in mobile, computing, consumer electronics, and Internet of Things (IoT) applications.
“We couldn’t be more happy to welcome Intel to CHIPS Alliance,” says Dr. Zvonimir Bandic, Chairman, CHIPS Alliance, and senior director of next-generation platforms architecture at Western Digital. “Intel’s selection of CHIPS Alliance for the AIB specifications affirms the leading role that the organization impacts for open source hardware and software development tools. We look forward to faster adoption of AIB as an open source chiplet interface.”
The CHIPS Alliance project develops high-quality open source Register Transfer Level (RTL) code and software development tools relevant to the design of open source CPUs, SoCs, and complex peripherals for field programmable gate arrays (FPGAs) and custom silicon. Intel’s AIB contribution is intended to encourage an industry environment in which silicon IP can be developed using any semiconductor process as a “chiplet,” and easily integrated with other chiplets into a single device to deliver new levels of functionality and optimization.
Broader adoption and support for AIB-enabled chiplets, says the organization, will help device developers grow beyond the limits of traditional monolithic semiconductor manufacturing and reduce the cost of development. Working together, Intel and CHIPS Alliance will encourage the growth of an industry ecosystem that engenders more device innovation via heterogeneous integration.
The AIB specifications and collateral will be further developed in the Interconnects workgroup. All AIB technical details will be placed in the CHIPS Alliance github. In addition, Intel will have a seat on the governing board of CHIPS Alliance.
