Notes to Table 7–4:
(1) In these modes, the host system must send a DCLK that is 4× the data rate.
(2) The enhanced configuration device decompression feature is available, while the Stratix II and Stratix II GX
decompression feature is not available.
(3) Only remote update mode is supported when using the AS configuration scheme. Local update mode is not
supported.
Configuration Data Decompression
Stratix II and Stratix II GX devices support configuration data
decompression, which saves configuration memory space and time. This
feature allows you to store compressed configuration data in
configuration devices or other memory and transmit this compressed bit
stream to Stratix II and Stratix II GX devices. During configuration,
Stratix II and Stratix II GX devices automatically recognize the
compressed file format and decompresses the bit stream in real time and
programs its SRAM cells.
1 Data indicates that compression typically reduces configuration
bit stream size by 35 to 55%.
Stratix II and Stratix II GX devices support decompression in the FPP
(when using a MAX II device/microprocessor + flash), AS, and PS
configuration schemes. Decompression is not supported in the PPA
configuration scheme nor in JTAG-based configuration.
