Minimal processing system design of laser alarmbased on MicroBlaze

为满足激光告警系统高角度分辨率与小型化设计兼容的需求,基于嵌入式系统开发流程,研究了MicroBlaze软核处理器的体系结构,设计并实现一个基于MicroBlaze软核的激光告警最小处理系统。该设计通过MicroBlaze软核搭建微处理器平台,与设备功能所需的外设IP核联合完成可编程系统芯片(SOPC)的设计,单片集成处理的设计使得信号流转发生在单个芯片内部,大大提高了数据运算速度与数据交互的实时性。实验结果表明,该系统很好实现了对激光信号的采集、处理,与外部设备串口通信结果符合预期。

In order to meet the design requirements of high angular resolution and miniaturization design of laser alarm system.Based on the embedded system development process,the architecture of MicroBlaze softcore processor was studied,and a minimum laser signal processing system based on MicroBlaze softcore was designed and implemented.The design uses MicroBlaze softcore to build a microprocessor platform,and other peripheral IP cores to complete the design of programmable system on chip(SOPC).The design of monolithic integrted processing enables the signal flow to occur inside a chip,which greatly improves the data operation speed and the real time data interaction.The experimental results show that the system can well realize the acquisition and processing of laser signals,and the communication results with the serial port of external devices meet expectations.
