In this thesis,we propose a color image processing
experiment environment designed by PC,TMS320C50 DSP processor
and AT89C51 single chip.In this environment, users can change
the setting on the circuit to fit various requirements.To deal
with huge amounts of color image data, we use DRAM for larger
capacity.For considering the processing speed,memory switching
method is designed on the circuit. Particularly,this thesis
focuses on the codec of the Wavelet Transform and Zerotree
Coding.And we can adjust the algorithm to fit the actual
conditions so that we can get the high compression ratio from
the acceptable quality for human eyes.
