IntAct consists of a 96 core architecture composed of 6 chiplets (FDSOI 28nm) 3D-stacked onto an active silicon interposer (CMOS 65nm), fully processed, packaged and tested.
In the context of HPC (High Performance Computing) and AI (Artificial Intelligence) acceleration, there is an ever increasing demand of computing capacity and solutions for specialization and energy efficiency..
The main IntAct prototype innovations are related to both technology and architecture:Technologies 3D avancée :
Advanced 3D Architecture : Active Interposer offers Network-on-Chip for chiplet-to-chiplet communication, scalable and configurable cachecoherent L1/L2/L3 architecture, integrated DC-DC converters for chiplet power supplies, system level IO's, Design-for-Test infrastructure, the whole architecture providing a cache coherent 96-core system.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
