FUNCTIONAL DESCRIPTION

CORE: Core module interconnects all the sub-modules in the USB1.x DEVICE IP. Ports of core module are the top level ports for the USB1.x DEVICE IP.

UTMI: Utmi interface signals transmits data as 8bit parallel data or 16 bit parallel data.

PHY: Phy will convert the parallel data received from utmi to serial data to transmit it and it will take care of remote wakeup, suspend ,resume and reset signalling.

PROTOCOL LAYER: protocol layer module takes care of packet disassembler and packet assembler and data processing in protocol engine.

CTRL: Ctrl module will take care of all standard device requests with respect to endpoint zero.

ROM1: Rom will store the descriptor details of endpoint zero from which the data can be retrieved.

ENDPOINT PROCESSOR: Endpoint processor will organize the endpoint config details with respect to transfer type, config type, and config size. It then mediates the data read and write and other signals from fifo.
