Abstract
A die-to-die (D2D) interface between chiplets of a system on a chip (SoC) in which each of the chiplets are subdivided into slices. The D2D interface includes a transmission interface coupled between first and second chiplets, which includes a first transmission path for a first slice and a second transmission path for a second slice. The first chiplet includes receive circuitry which further includes a write interface and a read interface. The write interface stores data received from the first transmission path into a first FIFO using a first clock signal received via the first transmission path, and stores data received from the second transmission path into a second FIFO using a second clock signal received via the second transmission path. The read interface reads data stored in the first and second FIFOs using the first clock signal. The first and second transmission paths may be subject to different delays.
