在实时计算机数据获取系统中,如果每获得一个实验数据就通过程序中断或DMA(直接内存访问)向计算机做传送,会占用较多的时间开销,降低整个系统的效率。为此,最好的解决办法是先将数据存入某个缓冲存储器中,当积累到一定数量时,再成批地送向计算机。 我们设计的双数据缓冲存储器CAMAC插件,便可方便地与任何数字编码设备(ADC)相连而构成带有数据缓冲的,可成批地向系统传送数据的数据获取系统。两个缓冲的容量
In a real-time computer data acquisition system, if an experimental data is obtained and sent to a computer through program interruption or DMA (direct memory access), it takes a lot of time overhead and reduces the efficiency of the entire system. To this end, the best solution is to first save the data in a buffer memory, when accumulated to a certain amount, and then sent to the computer in batches. Our double-data-buffered CAMAC plug-in is easily connected to any digital coding device (ADC) to create a data acquisition system with data buffering for batch transfer of data to the system.
