Interface Circuit Design and Programming for Storing the Data with TMS320VC5509 by Using Flash Memory
WU Nai-ling · Dianzi qijian · 2007
The main features of the TMS320VC5509 DSP are introduced briefly.Several aspects which should be paid attention to when storing the data with TMS320VC5509 by using flash memory are indicated in detail,such as interface circuit design,addressing the external data space,initializing the registers and detecting the program or erase operation to flash memory using DSP.Furthermore,the solution of accessing the flash memory AM29LV800 correctly at high frequency by appropriate delay is proposed,the program of which is given.The validity of solution is verified in practice.
