DSP peripheral extension module with bootloader function

TMS320VC54x series Digital Signal Processors(DSP) have no common peripherals, such as analog to digital convert(AD), digital to analog convert(DA) and lack of program memories. Therefore, peripheral expansion modules and bootloader module should be considered and designed in application system of this serie DSP. The traditional solution which has completed the modules respectively has the disadvantages of more expansion devices, lower degree of system integration. To overcome the problems mentioned in traditional solution, this paper proposed peripheral expansion module for DSP with the bootloader function. C8051F330 is the only outside chip which will be used in this module. Its internal FLASH is used to store bootloader program code of DSP and its on-chip AD and DA are used to realize DSP peripheral extension. Experiments show that the proposed DSP peripheral extension module is reasonable.
