Multi-mode data link system with external download function and method therefor

Abstract

The application discloses a multi-mode data link system with external download function and a method therefor, comprising an FPGA, an MCU main control module, a first FLASH module, a second FLASH module, a gate, a transceiver link module, an interface module, a power module, and a clock module. The FPGA performs the main data processing and module configuration functions. The MCU main control module receives the control commands from the interface module and performs the working mode selection with FLASH. The interface module also provides a data channel for external download. The transceiverlink module performs data conversion and transmission. The power module supplies power to the system. The clock module provides a clock signal to the FPGA. The multi-mode data link system with external download function can be used for the hardware architecture of the FPGA multi-loading of the miniaturizing multi-mode data link terminal, configuration programs can be loaded for different working modes according to specific usage requirements to perform multi-mode selection, and upgrade or replacement of program can be performed through external download function.

Description

technical field [0001] The invention belongs to the technical field of software radio and communication anti-interference, and relates to a multi-mode selection system, which is applied to FPGA multi-mode loading of data link terminals that require miniaturization, high performance, high integration, high reliability, and multi-mode communication requirements. , and has an external download function. Background technique [0002] Miniaturization and high integration are an important trend in the development of weapon data link terminals. With the development of device technology and the advancement of design methods, the signal processing and communication circuits work at higher and higher speeds, with higher power and more complex and intense noise distribution. At the same time, with the continuous improvement of high-speed and high-frequency chip integration, Shape and weight are getting smaller and smaller. The rapid development and rapid replacement of new large-scal...
