4.1 System Software Architecture
Figure 4-1. System Software Architecture
Figure 4-1
shows the system software architecture for the UF32 Thumb Drive. The mini-kernel is
designed for the multi-tasks operation. In this application, mini-kernel is mainly working for the USB event
task after system initialization. The initialization subroutines are for the system initialization, such as for
timer module, 3.3 voltage regulator, SM module, IQUE module, IQUE RAM mapping, SM RAM for logical
to physical look up table and USB module.
The main program continually checks the tasks and to serve the event once the request is made. It will
decode to invoke the SCSI commands if the request is made from PC via USB2.0 interface.
All data will pass through the IQUE RAM and read/write to NAND Flash.
