A design scheme of drive-and-control unit for resistor array is studied. According to this design, the drive-and-control unit is able to drive 128 × 128 resistor array working at 200 Hz frame frequency, farther, driving 256×256 resistor array at 100 Hz frame frequency is achievable. To satisfy the high speed performance demand, several techniques such as FPGA, bi-port RAM, PC104 and reflective memory network were applied. The resolvent of the key problems of drive and control of resistor array, such as high-speed transmission of image data and high-speed production of drive-and-control signal were studied. The application of PC104, FPGA and reflective memory network techniques also make the system upgradable and extendable for the future use in the drive and control task of 256 × 256 resistor array.
