Embodiment Construction

[0037] The system structure of terminal reconfiguration under the end-to-end reconfiguration environment of the present invention is as follows figure 1 As shown, it is composed of three types of hardware, ARM, FPGA and DSP. Among them, the terminal reconfiguration controller and reconfigurable application layer software are loaded on the ARM, the reconfigurable physical layer logic is loaded on the FPGA, and the reconfigurable MAC layer software is loaded on the DSP.

[0038] Two interfaces are equipped between ARM and FPGA. One is a JTAG interface, through which the terminal reconfiguration controller downloads the physical layer reconfiguration file to be replaced to the FPGA. The other is a parallel data interface, through which the terminal reconfiguration controller transmits reconfiguration parameters to the FPGA and receives feedback information of reconfiguration execution results of the FPGA. When nGCS2 of ARM outputs a high level to the CS pin of FPGA, the 8-bit a...
