Configuration Data Decompression
Cyclone IV 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 send the
compressed bitstream to Cyclone IV devices. During configuration, Cyclone IV
devices decompress the bitstream in real time and program the SRAM cells.
Preliminary data indicates that compression reduces the configuration bitstream size
by 35 to 55%.
When you enable compression, the Quartus II software generates configuration files
with compressed configuration data. This compressed file reduces the storage
requirements in the configuration device or flash memory and decreases the time
required to send the bitstream to the Cyclone IV device. The time required by a
Cyclone IV device to decompress a configuration file is less than the time required to
send the configuration data to the device. There are two methods for enabling
compression for the Cyclone IV device bitstreams in the Quartus II software:

To enable compression in the compiler settings of the project in the Quartus II
software, perform the following steps:
1. On the Assignments menu, click Device. The Settings dialog box appears.
2. Click Device and Pin Options. The Device and Pin Options dialog box appears.
3. Click the Configuration tab.
4. Turn on Generate compressed bitstreams.
5. Click OK.
6. In the Settings dialog box, click OK.
