Intel StrataFlash Parallel NOR Flash
PROM
As shown in Figure 11-1, the MicroBlaze Development Kit boards includes a 128 Mbit (16
Mbyte) Intel StrataFlash parallel NOR Flash PROM. As indicated, some of the StrataFlash
connections are shared with other components on the board.
The StrataFlash PROM provides various functions:
x Stores a single FPGA configuration in the StrataFlash device.
x Stores two different FPGA configurations in the StrataFlash device and dynamically
switch between the two using the Spartan-3E FPGA’s MultiBoot feature.
x Stores and executes MicroBlaze processor code directly from the StrataFlash device.
