Arria GX FPGAs support decompression of configuration data, 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 bitstream to Arria GX FPGAs. During configuration, the Arria GX FPGA
decompresses the bitstream in real time and programs its SRAM cells. Arria GX
FPGAs support decompression in the FPP (when using a MAX II device or
microprocessor and flash memory), AS, and PS configuration schemes.
Decompression is not supported in the PPA configuration scheme nor in JTAG-based
configuration.
Shortened design cycles, evolving standards, and system deployments in remote
locations are difficult challenges faced by system designers. Arria GX devices can help
effectively deal with these challenges with their inherent re programmability and
dedicated circuitry to perform remote system updates. Remote system updates help
deliver feature enhancements and bug fixes without costly recalls, reduce time to
market, and extend product life.
Arria GX FPGAs feature dedicated remote system upgrade circuitry to facilitate
remote system updates. Soft logic (Nios
Arria GX device can download a new configuration image from a remote location,
store it in configuration memory, and direct the dedicated remote system upgrade
circuitry to initiate a reconfiguration cycle. The dedicated circuitry performs error
detection during and after the configuration process, recovers from any error
condition by reverting back to a safe configuration image, and provides error status
information. This dedicated remote system upgrade circuitry avoids system
downtime and is the critical component for successful remote system upgrades.
Remote system configuration is supported in the following Arria GX configuration
schemes: FPP, AS, PS, and PPA. You can also implement remote system configuration
in conjunction with Arria GX features such as real-time decompression of
configuration data for efficient field upgrades.
