Division arithmatic unit of variable radix

A variable radix divider employing dividend, divisor and quotient as division operators and comprising:

• an adder/subtractor having inputs of the dividend and divisor;
• a first quotient/radix generator having inputs of the dividend and the divisor;
• a second quotient/radix generator having inputs of the dividend and the divisor;
• a first multiplexer having input of output from the first quotient/radix generator;
• a second multiplexer having input of output from the second quotient/radix generator;
• and
• each of the first and second quotient/radix generators including:
• a prediction adder/subtractor having inputs of bits in prediction range of the dividend and bits in prediction range of the divisor;
• a radix generator;
• and a quotient generator, the radix generator and the quotient generator having input of output of the prediction adder/subtractor;
• wherein the variable radix divider iterates a recursive cycle operation until division operation through a feedback path to the dividend is completed, the first and second multiplexer have input of the output of the adder/subtractor and determine in advance which one is to be the quotient and which one is to be the radix with respect to potential scenarios during the adder/subtractor is in operation.
