| Abstract: | Some brief characteristics of TI company's digital signal processor TMS320VC5510 and flash memory AM29LV160MB are introduced.In the state of simulation,a method of using TMS320VC5510 DSP to program flash in language C is given.According to the hardware,the schematic is designed;It is important to program the CMD file;Some details should be careful.With CMD file,converting the COFF file to HEX file can be implemented.The HEX file can not directly write in FLASH,the title of file and saved must be removed as a means of array.According to the command of FLASH,the erase and program operations should program.The Data# Polling bit,DQ7,indicates to the host system whether an erase Algorithm is in progress or completed.Toggle bit on DQ6 indicates whether an Embedded Program is in progress or complete.A way to further development develop something based on C5000 is presented. |
