摘　　要：本文描述一个４通道平行压频转换系统智能接口的硬件设计及其专用集成电路的实现。该接口可以设定压频转换积分时间并可通过内部集成的一个通用异步接收器发送器将转换数据送至微机处理。该接口采用一片用户可编程门阵列（ＦＰＧＡ）实现，故具有设计周期短。This paper describes hardware design and ASIC implementation of an intelligent interface for a 4 channel parallel voltage to frequency conversion (VFC) system. The interface can setup integration periods for VFC. In addition, with an internally integra ted universal asynchronous receiver transmitter (UART) the interface can transfer acquired data to a microcomputer for processing. The application specific integrated circuit (ASIC) of the interface is implemented in a field programmable gate array (FPGA) chip, which has such features as short time to market and flexibility in design and modification.
