摘要: 针对目前星载计算机只能进行任务管理、无法完成复杂数据运算的问题,基于数字信号处理器和现场可编程门阵列技术,设计并实现一种星载数据处理系统。在该系统中,数字信号处理器控制整个系统,并完成部分信号处理任务。现场可编程门阵列则完成其余的数据处理任务。测试结果表明,该系统具有较高的容错能力和可重构性,能够满足空间数据处理要求。

Abstract: Most of the on-board computers can only manage the task and can not complete the complex data operation. Aiming at this problem, this paper implements an onboard data processing platform, the core of which is the Digital Signal Processor(DSP) and Field Programmable Gata Array(FPGA). The DSP controls the whole system and completes some signal processing tasks. FPGA completes most of the signal processing tasks. Test result shows that the unit has a high capability and reliability, and can meet the requirements of space data processing.

Key words: onboard computer, high speed data processing, Digital Signal Processor(DSP), reliability design, reconfiguration, second-level boot loader
