Embodiment Construction
[0035] The specific implementation method described in the present invention takes the Virtex-4 XQR4VSX55 SRAM type FPGA which can realize dynamic partial reconfiguration launched by Xilinx Company as an example, and it can be dynamically reconfigured.
[0036]Step 1: Select Xilinx's Virtex-4 XQR4VSX55 SRAM FPGA, and use the ISE tool to divide the resources on the FPGA into a reconfigurable area and a static area. Configure the static area function, configure it as a partial reconfiguration controller (PRC, Partial Reconfiguration Controller), configuration interface and system internal connection line (PLB, Processor Local Bus), and the PLB connects all components and memory controllers to the control unit . Since the static area is configured with relatively critical modules, which occupy less resources and cannot be partially reconfigured, all structures in this area are protected by TMR to shield the accumulation of SEU in the static area.
[0037] Step 2: Construct a...
