TSARLET was a research microarchitecture designed by CEA-Leti demonstarting the theoretical capabilities of a large-scale high-performance 3D stacked chiplets-based SoC technology. The project comprised 96 MIPS cores built using 6 chiplets 3D stack on an active interposer in order to demonstarte in-package silicon scale-out capabilities with superior inter-chip capabilities while reducing the overall power and production cost.
