Modulo divider and modulo division operation method for binary data

A modulo divider for binary data, comprising:

• a first register, storing a first variant;
• a second register, storing a second variant;
• a third register, storing a third variant;
• a fourth register, storing a fourth variant;
• a first logic mapping circuit, coupled to the first register and the second register, and converting the first variant and the second variant to a variant set according to a first mapping table;
• a second logic mapping circuit, coupled to the first logic mapping circuit, and obtaining the variant set based on a first instruction from the first logic mapping circuit;
• a first calculation circuit, coupled to the first logic mapping circuit, and generating a fifth variant and a sixth variant according to the variant set
• a second calculation circuit, coupled to the second logic mapping circuit, and generating a seventh variant and an eighth variant according to the variant set;
• a first switching circuit, coupled to the first calculation circuit, the first register, and the second register, wherein the first switching circuit updates the first variant according to one of the fifth variant and the sixth variant, and updates the second variant according to another one of the fifth variant and the sixth variant;
• a second switching circuit, coupled to the second calculation circuit, the third register, the fourth register, and the first switching circuit, wherein the second switching circuit updates the third variant according to one of the seventh variant and the eighth variant based on a second instruction from the first switching circuit, and updates the fourth variant according to another one of the seventh variant and the eighth variant;
• and
• a processor, coupled to the second register, wherein the processor determines whether an updating of the third variant is finished, and outputs the third variant as a result of the modulo division operation in response to determining the updating of the third variant is finished.
