A mechanism used by tasks and interrupt service routines to share information and synchronize their access to shared resources 一种被用来在任务和中断服务程序之间共享信息和同步它们对共享资源访问的机制。
The software in this system includes a monitor program , a lcd display program , an interrupt service program , a computing program and so on 该系统的软件主要包括监控程序、中断服务程序、计算程序和显示程序等。
Drivers for devices that generate hardware interrupts will have an interrupt service routine ( isr ) and a deferred procedure call ( dpc ) routine 对于普通硬件中断设备的驱动要具有中断服务程序（ isr ）和一个延迟程序调用（ dpc ）程序。
The data exchange between the background isr ( interrupt service routine ) and the foreground main loop is achieved by event flags and data buffers 整个固件程序设计成完全的中断驱动方式，后台中断服务程序( isr )和前台主循环之间的数据交换通过事件标志和数据缓冲区来实现。
Finally , this paper discussed the software system design based on above hardware platform , including the dsp initialization program , the interrupt request service and speech coding 最后讨论了基于上述硬件系统的软件设计,主要分为三个部分: dsp的初始化程序、中断服务程序和语音编解码程序。
The measurement of the time interval of ultrasonic send wave and echo used the catch method of 52 series mcu , and avoided the error that the isr save the current value of counter 超声波发射波和回波的时间间隔的测量利用了52系列单片机的捕获方式，避免了因为借助于中断服务程序来保存计数器的当前值所带来的误差。
A table containing interrupt vectors and indexed by interrupt type . this table contains the processor " s mapping between interrupts and interrupt service routines and must be initialized by the programmer 一个表格，包含由中断类型决定的中断向量和索引。这个表格包含中断与中断服务程序之间的处理器的映射，必须由程序员进行初始化。
The software includes a monitor program , an initialization module , a watchdog module , a data fusion module , a can transmission module , a quadrature encoder pulse count module and an a / d interrupt service program 该系统软件包括监控程序、初始化模块、看门狗模块、数据融合模块、 can通信模块、数字量采集模块、正交编码脉冲计数模块和a d中断服务程序。
The lower computer system software was developed with 8098 assemble language of mcs - 96 series and composed of modules of main program , time interrupt service routine , receiving interrupt service routine , data collection subroutine , data processing subroutine and control subroutine 下位机系统软件采用mcs - 96系列的8098单片机汇编语言来开发，主要由主程序模块、定时中断服务程序模块、接收中断服务程序模块、数据采集子程序模块、数据处理子程序模块和控制子程序模块组成。
Therefore , through comparing schemes , we select the ultralow power , high integration msp430f43x series microcontrollers as the center . on software , we take full advantage of the low power modes of the mcu to finish the task in isr ( interrupt service routine ) , so , the power of system rest with the isr executive time 因此，在硬件选择上，通过方案比较，选用微功耗、高集成度的msp430f43x系列单片机作为控制核心；在软件设计上，充分利用所选单片机的低功耗模式，让检测任务在中断服务程序中完成，使系统的功耗主要取决于中断服务程序执行的时间。
