摘要： A method for performing decimal division including receiving a scaled divisor and dividend and storing a subset of the multiples of the scaled divisor. An accumulated quotient is initialized to be equal to zero, a first current remainder is initialized to be equal to the scaled dividend, and a second current remainder is initialized to be equal to the scaled dividend minus the scaled divisor. The following loop is performed until a selected number of quotient digits are produced. An estimated next quotient digit is calculated based on the first digit of the first current remainder. A temp remainder is selected to be either the first current remainder or the second current remainder based on the estimated next quotient digit. A first next remainder is calculated by subtracting one of the stored multiples from the temp remainder, where the stored multiple is selected based on a first digit of the first current remainder. A second next remainder is calculated by subtracting an other one of the stored multiples from the temp remainder, where the other one of the stored multiples is selected based on the first current remainder. An actual quotient digits is calculated based on the estimated next quotient digit, the first current remainder and the first next remainder. The accumulated quotient is updated with the actual next quotient digit. Finally, the first current remainder is set to be equal to the first next remainder and the second current remainder is set to be equal to the second next remainder.

摘要： A method for converting from binary to decimal. The method includes receiving a binary number, the binary number including one or more sets of bits. An accumulated sum is set to zero. The accumulated sum is in a binary coded decimal (BCD) format. The following loop is repeated for each set of bits in the binary number in order from the set of bits containing the most significant bit of the binary number to the set of bits containing the least significant bit of the binary number: the accumulated sum is converted into a 5,1 code format resulting in an interim sum. The loop also includes repeating for each next bit in the set in order from the most significant bit to the least significant bit in the set: doubling the interim sum; and replacing the least significant bit of the interim sum with the next bit. The last step in the loop includes converting the interim sum into the BCD format and storing the results of the converting in the accumulated sum. Once all of the sets of bits in the binary number have been processed through the loop, the accumulated sum is output as the final result.

摘要： A system for performing decimal multiplication including input registers for inputting a multiplier and a multiplicand. The multiplier includes one or more digits. The system also includes one or more two cycle adders and mechanism. The mechanism receives the multiplier and the multiplicand into the input registers. A running sum is reset to zero. The mechanism also performs for each of the digits in the multiplier in order from least significant digit to most significant digit: creating a partial product of the digit and the multiplicand; and adding the partial product to the running sum using the two cycle adders. When the loop is completed for each of the digits in the multiplier, the mechanism outputs the running sum as the result.

摘要： A system for performing decimal floating point addition. The system includes input registers for inputting a first and second operand for an addition operation. The system also includes a plurality of adder blocks, each calculating a sum of one or more corresponding digits from the first operand and the second operand. Output from each of the adder blocks includes the sum of the corresponding digits and a carry out indicator for the corresponding digits. The calculating is performed during a first clock cycle. The system also includes an intermediate result register for storing the sums of the corresponding digits output from each of the plurality of adder blocks, the storing during the first clock cycle. The system further includes a carry chain for storing the carry out indicator output from each of the plurality of adder blocks, the storing occurring during the first clock cycle. The system further includes an incrementer for adding one to each of the sums stored in the intermediate result register, the incrementing occurring during a second clock cycle. In addition, a mechanism is provided for selecting between each of the sums and the sums incremented by one. The input to the mechanism includes the carry chain. The output includes the final sum of the first operand and the second operand. The selecting occurs during the second clock cycle.

摘要： A method for converting from binary to decimal. The method includes receiving a binary coded decimal (BCD) number made up of one or more sets of three digits. A running sum and a running carry are set to zero. The following steps are performed for each set of three digits in the BCD number in order from the set of three digits containing the three most significant digits of the BCD number to the set of three digits containing the three least significant digits of the BCD number. The steps include: creating six partial products based on the set of three digits, the running sum and the running carry; combining the six partial products into two partial products; and storing the two partial products in the running sum and the running carry. After the loop has been performed for each set of three digits in the BCD number, the running sum and the running carry are combined into a final binary result.

摘要： A method for performing a decimal floating point operation. A first operand including a first coefficient and a first exponent is received. The method also includes receiving a second operand that includes a second coefficient and a second exponent. An operation associated with the first operand and the second operand is received. The operation is an addition or a subtraction. Three concurrent calculations are performed on the first operand and the second operand. The first concurrent calculation includes applying the operation to the first operand and the second operand based on a first assumption that the first exponent is equal to the second exponent. The applying the operation based on the first assumption results in a first result and includes utilizing a two cycle adder. The second concurrent calculation includes applying the operation to the first operand and the second operand based on a second assumption that an absolute difference between the first exponent and the second exponent is less than or equal to a number of leading zeros in the coefficient of the operand with the larger exponent. The applying the operation based on the second assumption results in a second result and includes utilizing the two cycle adder. The third concurrent calculation includes applying the operation to the first operand and the second operand based on a third assumption that the absolute difference between the first exponent and the second exponent is greater than the number of leading zeros in the coefficient of the operand with the larger exponent. The applying the operation based on the third assumption results in a third result and includes utilizing the two cycle adder. A final result is selected from the first result, the second result and the third result.

摘要： A method for leading zero detection. The method includes receiving DPD encoded data representing a three digit BCD number and determining directly from the DPD encoded data if the BCD number represented by the DPD encoded data contains at least one leading zero digit. A group one switch is set to zero if it was determined that the BCD number represented by the DPD encoded data contains at least one leading zero digit and set to one otherwise. The method also includes determining directly from the DPD encoded data if the BCD number represented by the DPD encoded data contains at least two leading zero digits. A group two switch is set to zero if it was determined that the BCD number represented by the DPD encoded data contains at least two leading zero digits and set to one otherwise. The method further includes determining directly from the DPD encoded data if the BCD number represented by the DPD encoded data contains three leading zero digits. A group three switch is set to zero if was determined that the BCD number represented by the DPD encoded data contains three leading zero digits and set to one otherwise.
