The intermediate result is encoded in a binary representation and appended at the beginning by an encoded counter.
该中间结果用二进制形式编码表示,并通过一个经过编码的计数器逐渐增加。
This binary string is comprised of the usual counter, which is needed for the DB2 MAX function to do the actual aggregation, the identifier for the aggregate object, and the group identifier.
这个二进制串由常用的计数器(DB 2max函数进行实际聚集计算时需要)、聚集对象的标识以及分组标识构成。
A serial-down binary counter is needed.
需要一个串行累减二进制计数器。
The maximum count of a combination counter is thus a function of the number of stages of the binary and feedback counters .
组合计数器的最大数值是二进制计数器和反馈计数器的级数的函数。
The counter output, which represents a binary number, decreases by 1 any time the counter is triggered by a pulse .
每当计数器被时钟脉冲触发一次时,计数器输出的二进制数便累减1。
This can be easily done by nothing that, for a binary counter, any given digit changes its value (from 1 to 0 or from 0 to 1) whenever all the previous digits have a value of 1.
这很容易做到,注意,对于二进制计数器,只要所有前面的数字都是1,任何给定的数字都会改变它的值(从1变为0,或者从0变为1)。
Finally an analytic comparison is made between those two kinds of counters in both their circuit structure and economic property, and hence the advantages of the binary-N carry counter are proved.
最后,就这两种计数器在电路结构和经济性能方面进行了分析比较,论证了二—N进制计数器的优点。
This paper proposes the design method of a mixedvalued modulo-N synchronous counter by using both common binary flip-flops and ternary T flip-flops which has binary structure.
提出用纯二值结构的三值T触发器和普通的二值触发器一起构造混值N进制计数器的设计方案。
Compared with the ordinary binary counter, it has high stability and flexibility. This method is a reference to design of counter.
和普通的二进制计数器相比具有很好的稳定性和可靠性,为计数器的设计提供了参考。
