Abstract :
A controller for contact image sensor (CIS) is designed based on CPLD and VHDL. The controller includes a controller of timing driver for CIS, a controller of analog-to-digital converter, a storage of data, a switch of memory bus and a interface to MPU. The simulated waveform diagram of VHDL program is also provided in the paper. The controller works well in the paper currency sorting machine.
