Embodiment Construction

[0026] The invention realizes the independent reconfiguration of the SoPC chip by constructing a configuration data link inside the SoPC chip BM3109. The SoPC chip BM3109 reads the configuration file of the FPGA from the storage space inside the chip according to the changes of the external environment and the requirements of the task, and loads the configuration data into the FPGA through the soft configuration interface. The self-reconfiguration operation is as follows: figure 1 As shown, the self-reconfiguration operation of the SoPC chip is as follows figure 2 shown. Among them, BM3109 includes external memory FLASH, SPARC V8 processor and FPGA.

[0027] Aiming at this special application background, the present invention conducts research on the realization scheme of SoPC chip BM3109 self-reconfiguration. A SoPC chip autonomous reconfiguration soft configuration method is proposed. Make full use of the controllability of the configuration interface, connect the GPIO i...

Abstract

A SoPC chip self-reconfiguration soft configuration method, the SoPC chip self-reconfiguration soft configuration circuit technology is studied, and a SoPC chip self-reconfiguration soft configuration method is proposed, and the method of the invention fully utilizes the characteristics of the controllability of the configuration interface , connect the GPIO interface of the processor with the configuration interface of the FPGA chip, construct the physical data path and configuration link, realize the configuration timing and configuration data by controlling the signal output and collection of the GPIO interface, and change the interface level, and complete self-reconfiguration operate. Compared with the traditional reconfiguration configuration method, the method of the present invention can realize the autonomous reconfiguration operation of the system without adding an FPGA-specific configuration chip to the SoPC chip, effectively reducing the volume of the SoPC chip, and at the same time, the interior of the SoPC chip is used for control and realization. There are fewer signals for autonomous reconfiguration operations, which reduces design complexity.

Description

technical field [0001] The present invention relates to a chip autonomous reconfiguration soft configuration method, in particular to a SoPC chip autonomous reconfiguration soft configuration method, enabling the chip to have intelligent autonomous reconfiguration and on-orbit upgrade capabilities of hardware tasks in an outer space environment . Background technique [0002] Traditional on-board electronic systems include a large number of discrete devices and small-scale integrated circuits. More printed boards and stand-alone machines increase the volume and power consumption of the whole machine, and the complex interconnection structure reduces system reliability. , obviously, the traditional electronic system will be difficult to meet the development needs of future spaceborne computer miniaturization. [0003] The domestic SoPC chip BM3109 is more in line with the needs of the development of electronic systems. In the spatial dimension, data calculation and processi...
