摘　　要：目的:应用FMl8L08完成DSP外围存储器扩展。方法:利用FMl8L08具有的随机读取速度快、非易失性及与标准SRAM管脚兼容等特性,设计与TM320F2812接口。结果:系统应用FMl8L08独立作为DSP TMS320F2812外围存储器扩展,替代了传统ROM和SRAM分立设计,可将其应用到12导心电图机的开发中。结论:简化了系统硬件和软件设计,增加了系统的可靠性,降低了功耗。Objective To expand peripheral memory of DSP by using FM18L08. Methods Because FM18L08 not only can be randomly read in high speed, but is non-volatile and compatible with the pins of SRAM, the interface to TMS320F2812 was designed based on FM18L08. Results FM18L08 is used as TMS320F2812 peripheral memory expansion, instead of traditional separate ROM and RAM design, and be applied to the 12-lead ECG development. Conclusion This scheme can predigest software and hardware design complexity, enhance the system stabilization and decrease the power consumption.
