Low-cost and high-performance computer used for space

Abstract

The present invention discloses a low-cost and high-performance computer used for space. The computer comprises: 3 dual-core CPUs, 3 sets of dynamic memories, 3 program memories, an arbitration and bus extension FPGA, a PCIe bus exchange chip, and a gigabit network bus exchange chip. The dual-core CPU is provided with multiple types of external interfaces; the dynamic memory provides an external extension memory for the CPU; the program memory provides program storage space for the CPU; the arbitration and bus extension FPGA performs and determination and arbitration on an operating state of the CPU, and selects an HDLC low-speed bus of an on-duty CPU to input and output externally; the PCIe bus exchange chip is responsible for integrating each two PCIe buses of the 3 CPU into two external PCIe buses; and the gigabit network bus exchange chip is responsible for integrating each two gigabit network interfaces of the 3 CPUs into two external pre-network interfaces. The computer not only reduces external nodes but also guarantees signal quality and bandwidth.

Description

Technical field [0001] The present invention relates to a computer device for electronic equipment used in space, in particular to a low-cost and high-performance space computer. Background technique [0002] Space computers have a wide range of applications in the fields of spacecraft attitude and orbit control, data processing, and payloads. With the development of miniaturization, integration, integration and commercialization of satellites, more and more space computers need to be realized. Function. Therefore, higher and higher requirements are put forward for the data processing capability, data throughput, power consumption, cost, and the richness of external interfaces of the space computer. At present, commonly used space computers often cannot meet these increasingly high requirements. In addition, considering the complex space environment, computer systems used in space must also have high reliability and single-particle resistance. Summary of the invention [0003] ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a low-cost high-performance space computer, to solve the problem that existing space computers generally cannot satisfy the data processing capability, data throughput, and performance of space computers in existing space applications.
