频谱仪多种内核间通信机制的方案设计

Communication Scheme for Spectrum Analyzer Multi-core

手持式频谱仪系统采用的是ARM、DSP、FPGA的三核架构。对于多核架构,保证内核间的通信尤为重要。对于内核间通信,首先是对通信接口的硬件设计与通信机制的研究,然后着重介绍ARM支持下的嵌入式Linux的接口设备驱动的开发,包括通信接口HPI、SPI的驱动。最后完成驱动测试,整个系统运行稳定。

Hand held spectrum analyzer system is designed based on the three core structure of ARM, DSP and FPGA. For multi core architecture,to ensure communication between cores is particularly important. This paper first introduces the hardware design of communication interfaces and the communication mechanisms, and then emphatically introduces the development of embedded Linux device driver based on ARM,including the communication interface driver of HPI and SPI. Finally,the system carries out the driver testing to en sure stable operation of the entire system.
