Development of Data Acquisition System using VLSI

Development of Data Acquisition System using VLSI is basically designed to keep the track of the temperature data entering the system, process it and display it on a PC. This VLSI-based Data Acquisition System works as a data logger for measuring the temperature data at different conditions. UART module is used as communication interface between CPLD kit and PC. In this paper, we designed the hardware part as we ll as software implementation part of our system to measure the temperature with the help of temperature sensors and the result is stored in Personal Computer for post process analysis. First the input temperature is detected in analog form and then converted to digital form using analog-digital convertor and then through level convertor it is implemented on CPLD kit. On CPLD kit, VHDL coding is done in Xilinx to read the data entered and logic is being implemented to transfer it to PC for display via serial port using UART. The input data will be synthesized on CPLD device and simulation results can be seen on PC.
