I found reconfigurable device is a hot research region, does any FPGA nowadays support reconfiguration? I heard that Atmel has a chip can do that work.
Thanks!

I wonder what you really wanted to ask. All SRAM based FPGAs are reconfigurable.... if u meant to ask dynamic/on the fly reconfiguration .. i guess that is also possible with todays fpgas..

The configuration bitstream size for Altera FPGA is documented in the device datasheets, also the maximum configuration clock rate, so you are able to calculate configuration times.No, Altera® FPGA devices do not support partial device reconfiguration of the SRAM array (CRAM). The FPGA architecture does not have the ability to reconfigure a certain portion of the configuration memory in the FPGA while not disrupting the device operation in user mode.
When pulsing nCONFIG to start the device reconfiguration, the entire device will be erased and reconfigured with the new configuration data.
Some device families support reconfiguration of specific features, such as PLL and transceiver reconfiguration. These options are described in the respective device handbook.
