3. Whole system block diagram is show as below:
Overview
The Main Board of PB6100 is mainly composed of an ADC converter(AD9883) , a
ImageProcessor(PW166) , a EEPROM(24C16) and a flash memory (MBM29LV800B) .
The input signal is analog RGB format , which comes from the standard VGA D_SUB connector ,
the analog signal input to ADC converter , which output RGB digital data stream to Image Processor .
The Image Processor also known as “Scaler” , which indicate its main function , expand or
downsize the digital picture from ADC to a fixed size digital image output .
The CPU which control the whole system is embedded inside the Image Processor , there is also
a Real Time Operating System which incorporates with the CPU as hardware layer interface .
The EEPROM stores the system information such as brightness , contrast …which ensure the
system operates under the most user friendly circumstance .
The Flash memory stored the Software Program which control the system , the CPU will read the
Flash as its execution command .
