除法器的设计本文所采用的除法原理是：对于八位无符号被除数A，先对A转换成高八位是0低八位是A的数C，在时钟脉冲的每个上升沿C 向左移动一位，最后一位补零，同时判断C的高八位是否大于除数B，如是则C的高八位减去B，同时进行移位操作，将C的第二位置1。否则，继续移位操作。经过八个周期后，所得到的C的高八位为余数，第八位为商。从图(1)可清楚地看出此除法器的工作原理。此除法器主要包括比较器、减法器、移位器、控制器等模块。-Divider design used in this paper, the principle of division is: For the eight unsigned dividend A, the first of A into the high-low 8 0 8 is the A number of C, in each clock rising edge to the left C Mobile One, and finally a zero, at the same time to determine whether C is greater than the high-8 divisor B, so is the high C 8 minus B, at the same time shift operation, the location will be C s second one. Otherwise, continue to shift operation. After eight cycles, received a high C for more than eight the number of eighth place for the business. From Figure (1) can clearly see that the divider works. This mainly includes divider comparators, subtraction, and shifter, controller modules.
