Embedded multi-task management device

Abstract

The invention discloses an embedded multi-task management device, which comprises an MCU processor, and a program memory, a data memory A, a verification memory and an FPGA controller in electrical connection therewith, and a fiber interface, a 1553B interface, an LVDS interface, an RS422 interface and a data memory B in electrical connection with the FPGA controller respectively, and a power supply module for supplying power for the memories, the interfaces, the processor and the controller. According to the embedded multi-task management device in the invention, the external interfaces are rich from the low-speed 1553B bus, the RS422 bus to the high-speed LVDS bus and the optical fiber, covering all communication interfaces commonly used at present, thereby meeting the general design requirements; the transmission bandwidth is high, from 1Mbps to 4.25Gbps, and the transmission bandwidth is increased by 3 orders of magnitude; the extensibility is strong; the storage capacity of the program memory, the data memory A, the verification memory and the data memory B, and the number of the optical fibers, the 1553B interfaces, the LVDS interfaces and the RS422 interfaces are all expanded or backed up according to the actual needs so as to meet the design needs of different functional radars.

Description

technical field [0001] The invention relates to a space-borne phased array radar task management technology, in particular to an embedded multi-task management device. Background technique [0002] The task management board is one of the important components of the spaceborne phased array radar, and it mainly completes the analysis, transmission and control functions of radar control commands. Specifically, the task management board is responsible for communicating with the satellite management platform, receiving the control commands sent by the platform for analysis and forwarding, controlling the next-level digital transceiver unit, and collecting the BIT status of each unit of the radar and sending it back to the satellite management platform . Because the previous functions of the task management board are relatively simple, the design usually uses an 8-bit microcontroller with CPLD or low-end FPGA to complete. The external interfaces of the task management board are ...
