Configurability of FPGAs
The usual FPGA technology permits FPGAs to be configured only once (using fusable links to yield a read-only FPGA)
or to be reconfigured before program start but not during run-time.
- Today, configurable FPGAs can be reconfigured application-dependent within milliseconds.
- In 1998, the Xilinx 4000 series offers 500 000 gates.
In principle, FPGA technology can be reconfigured much faster.
- E.g. XC6200 FPGA family of Xilinx allows to dynamically reconfigure the FPGA or parts of the FPGA during run-time.
- The XC6200 features fast partial reconfiguration, a built-in microprocessor interface and an open bit stream format.
- In 1998, the XC6264 FPGA of the Xilinx 6200 series offered the integration of 64 000 gates.
