Figure 5-2 Block diagram of the QDRII+ Demonstration
The system flow is controlled by a Nios II program. First, the Nios II program writes test
patterns into the whole 8 MB of SRAM. Then, it calls Nios II system function,
alt_dcache_flush_all()
, to make sure all data has been written to SRAM. Finally, it reads
data from SRAM for data verification. The program will show progress in JTAG-Terminal
when writing/reading data to/from the SRAM. When verification process is completed,
the result is displayed in the JTAG-Terminal.
