基于软件无线电平台的单片机加载DSP

In this paper it focuses on MCU(Microcontroller Unit) loading DSP based on SDR(Software Defined Radio) platform. Getting help from the thought of the rapid SDR, with the digital signal processing technological theory providing theoretic support, and with the MCU and DSP as technological platform, it provides in-depth discussion and study. The serial communicaition between PC and MCU, the master-slave communicaiton based on SPI protocol between MCU and DSP, and the MCU loading DSP based on SDR platform are involved in this paper. This paper is based on SDR platform. The communication based on the serial ports of MCU mainly realizes the serial communication between PC and MCU and is used to write the local DSP program into the MCU's external FLASH. The communicaiton based on the SPI protocol realizes the communication between MCU and DSP and thus makes MCU loading DSP program into reality. The application result shows that the loading method is feasible and effective.
