摘　　要：介绍一种通过采用数字信号处理器DSP(SMJ320F240)、IDE接口的电子盘和I2C总线接口的计时器来实现的实时数据记录模块,实现了对大容量数据的实时记录。该模块在某型雷达数据处理机系统中的实际应用表明该设计实用可行,并在大容量数据采集系统应用中具有典型性和通用性。This article mainly introduces the design of a record module which has been implemented in practice. This module is composed of DSP（SMJS20F240）,Flash disk with IDE interface and timer chip with I^2C bus. The module can be used to record large quantities of real - time data.Its successful implementation in one radar data processing unit proves that the design is efficacious and reliable. The design is a typical and practical example which can server as reference for similar real - time data record system.
