This paper presents a novel vehicle exhaust gas measurer based on CPLD. Because P89C668 single chip machine has only a UART, ISP programming port, micro-printer interface and last position machine communication port need to serial communication. To solve this contradiction, interface design is chose for EPM7128SLC84-15 chip, which single chip machine control and use one function. QUARTUS IIsoftware development tool and VHDL program language are adopted. modularization programming mode of CPLD is compiled, which every module has a corresponding VHDL file. The results show that design cost is reduced 18% and development cycle decrease to 15 month, vehicle exhaust gas measurer can meet expectant request.
