Realizing method for spaceflight SoC (System on a Chip) supporting partial reconstruction

Abstract

The invention relates to a realizing method for spaceflight SoC (System on a Chip) supporting partial reconstruction. A dynamic system and a static system are defined in an SoC, the two systems are differently designed, a logic of part of an FPGA (Field Programmable Gate Array) can be reconstructed during a running process of the systems. and the logic function of the part, which is not configured, of the FPGA. is not changed, so that the dynamic part can be reconstructed and has the flexibility of software and the high efficiency of hardware, the present state of unchangeable SOC interior function and structure at present is effectively settled, and meanwhile, through a partial reconstructing technique, a configuration bit flow can be periodically refreshed, the configuration bit flow is prevented from generating single event upset, the reliability and fault-tolerant ability of the SOC are increased, and the function of the SOC becomes more flexible.

Description

technical field [0001] The invention relates to a method for realizing an aerospace SoC supporting partial reconfigurability, and belongs to the field of highly reliable SoC design based on partial reconfigurability. Background technique [0002] In recent years, with the rapid development of electronic device miniaturization and low power consumption technology, ASIC-based system-on-chip (SoC) is being widely used in many high-reliability fields. Especially in the field of space applications, the use of SoC can significantly reduce the weight of devices, reduce the size of the system, and improve system performance. However, the internal function and structure of the SoC device cannot be changed after the design is finalized, and its adaptability is not high in the face of changing space missions. In addition, when a part of the function fails in the SoC, the system will lose the corresponding part of the failure. function, system degradation occurs, affecting the completi...

However, the internal function and structure of the SoC device cannot be changed after the design is finalized, and its adaptability is not high in the face of changing space missions. In addition, when some functions in the SoC fail, the system will lose the corresponding part of the failure. The function of the system will be degraded, which will affect the completion of the task
