WT-DIPLAB-1.0
Digital Image Processing Laboratory
Wavelet Technologies
Digital image processing laboratory (DIPLAB) is based on WT-DSPPORT-V.1 boards
having ADSP-BF561 dual core processor. One of the WT-DSPPORT-V.1 boards is used as
Pattern Generator and the other is used as Video Processor. DIPLAB is very good teaching
aid and helps students to understand different image processing concepts in a better way.
USB Emulator is provided along with the WT-DSPPORT-V.1 for developing and debugging
the algorithms and also for burning the loader file into flash memory. User can communicate
with WT-DSPPORT-V.1 boards on RS232 through HyperTerminal application running on Host
PC using commands.
