摘要
随着数字信号处理技术的飞速发展和DSP的广泛应用,作为其外挂的SPI EEPROM存储器也得到越来越多地关注和应用。基于TI公司的TMS320VC5502和ST公司的M45PE20开发系统为背景,着重介绍了硬件接口的设计、程序烧写和上电时正确的自举引导等关键技术问题,对烧写过程和自举引导时序作了详细的描述,在示波器上抓到了其过程波形,并且在实际应用中得到了验证。
With the rapid development of digital signal processing technology and the extensive application of DSP processor, SPI EEPROM memorizer is gaming more attention and extensive application. Based on the development systems of TI company＇s TMS320VC55（i2 and ST company＇s M45PE20, this paper mainly introduces such key technologies as hardware interthce design, program writing and right boot loader at power up time, describes in detail the process of program writing and the sequence of boot loader, gets the waveform of process on an oscilloscope, and verifies its feasibility in the practical application.
