Reconfigurable spaceborne computer capable of processing multiple tasks

Abstract

The invention discloses a reconfigurable spaceborne computer capable of processing multiple tasks. The reconfigurable spaceborne computer comprises an FPGA (Field Programmable Gate Array) chip, a storage unit and an ROM (Read Only Memory) configuration chip, wherein the storage unit and the ROM configuration chip are electrically connected with the FPGA chip; the storage unit comprises an SRAM (Static Random Access Memory) and a Flash; an FPGA internally comprises a main control unit and a configurable unit array; the main control unit comprises a soft core processor and a memory controller, an FPGA interior configuration port and an on-chip bus; the configurable unit array comprises a plurality of configurable units; and the soft core processor is electrically connected with the FPGA interior configuration port through the on-chip bus and the configurable units. According to the reconfigurable spaceborne computer capable of processing multiple tasks, each configurable unit keeps an on-chip bus port connected with the main control unit; the soft core processor calls for a circuit in the configurable unit randomly through the on-chip bus; the main control unit dynamically distributes and manages the FPGA resources through the FPGA interior configuration port, and a digital circuit with any function is also configured according to the specific requirement of the process of the task.

Description

technical field [0001] The invention relates to an on-board computer, in particular to a multi-task-oriented reconfigurable on-board computer, which belongs to the technical field of computer equipment. Background technique [0002] The development of satellite technology requires the on-board computer to have rich external interfaces, such as the I / O interface of the Shenzhou return capsule control computer with as many as 121 channels, and powerful computing capabilities, such as the data collected by the space telescope every day up to TB level; based on The reconfigurable spaceborne computer of reconfigurable technology has the advantages of high integration, flexible interface and strong computing power, which just meets the development needs of space technology, so it has been widely concerned and applied in the aerospace field. In recent years, with the continuous improvement of micro-satellite integration, more and more lower computers have been integrated into the c...

Problems solved by technology

In recent years, with the continuous improvement of micro-satellite integration, more and more lower computers have been integrated into the central computer. However, due to the lack of a field programmable logic gate array FPGA resource management mechanism, the traditional reconfigurable satellite computer It is not very suitable for multi-tasking work backgrounds. In the past, reconfigurable computers on stars were often used as an important reason for co-processors
