FUNCTIONAL DESCRIPTION

CORE: Core module interconnects all the sub-modules in the PCIe to UCIe Bridge IP. Ports of core module are the top level ports for the PCIe to UCIe Bridge IP.

CSR: CSR module has all the registers. The contents of the registers are decoded and assigned to its respective output ports based on its functionality.

ATU: Address translation unit Module translates the UCIe address to csr address.

Protocol layer: The protocol layer performs APB-to-UCIe bridge to transfer sideband data using UCIe sideband packet formats and the PCIe UCIe bridge manages high-speed data communication by converting PCIe transactions into UCIe mainband flits and reconstructing them on reception.

D2D adapter: The D2D Adapter module manages both sideband and mainband communication by packing, and unpacking sideband packets, while packaging protocol data into protected flits for reliable high-speed transfer between local and remote dies
