A chiplet is a small, modular chip that performs a specific function very well. For example, a chiplet can be a processor core, a memory block, an I/O driver, or a signal processing unit. Chiplets are designed to be used in a chiplet-based architecture, in which multiple chiplets are connected through a standardized high-speed digital interface, such as UCIe, to form a complete system-on-chip (SoC).
