3.2 System Description

3.2.1 GL800USB

The USB 2.0 UTMI Transceiver, which handles the low level USB protocol and

signaling, and shifts the clock domain of the data from the USB 2.0 rate to one that

is compatible with the general logic.

3.2.2 Serial Interface Engine

The Serial Interface Engine can be further sub-divided into 2 types of sub-blocks;

the SIE control logic and the Endpoint logic. The SIE control logic contains the

USB PID and address recognition logic, and other sequencing and state machine

logic to handle USB packets and transactions. The Endpoint logic contains the

endpoint specific logic: endpoint number recognition, FIFOs and FIFO control, etc.

SIE logic module can be developed by peripheral vendors or purchased from IP

vendors. The standardization of the UTMI allows multiple sources of SIE logic to

connect with GL800USB to implement the USB 2.0 High-Speed design.

3.2.3 Device Specific Logic

This block is the glue that ties the USB interface to the specific application of the

device.
