Design of High-Performance Vehicle Multi-Axis Optical Encoder Data Acquisition System Based on PC104 Bus

Abstract:

A high-performance vehicle multi-axis optical encoder data acquisition system based on PC104 bus is introduced. The paper puts emphases on the main function of the system module. VHDL hardware description language is used to design the modules, and ModelSim is introduced to implement logic and sequential simulation. An experiment is carried on in Altera EPF10K40 chip. Both the simulation and experimental results verify the correctness and validity of the method.
