METHOD AND APPARATUS FOR PERFORMING BIG-INTEGER ARITHMETIC OPERATIONS |
摘要 |
An apparatus and method are described for performing big integer arithmetic operations. For example, one embodiment of a processor comprises: a first source register to store a first 256-bit integer operand; a second source register to store a second 256-bit integer operand; and multiplication logic comprising a set of multipliers and adders to perform a multiplication of the first and second 256-bit integer operands to generate a 512-bit result responsive to a 256-bit multiplication instruction, the multiplication logic to convert a radix representation of the first and second 256-bit integer operands from a first radix representation to a second radix representation selected based on a size of the multipliers and adders used to perform the multiplication and generate a result, and then to convert the result back to the first radix representation. |

1. A processor comprising:
a first source register to store a first 256-bit integer operand; a second source register to store a second 256-bit integer operand; and multiplication logic comprising a set of multipliers and adders to perform a multiplication of the first and second 256-bit integer operands to generate a 512-bit result responsive to a 256-bit multiplication instruction, the multiplication logic to convert a radix representation of the first and second 256-bit integer operands from a first radix representation to a second radix representation selected based on a size of the multipliers and adders used to perform the multiplication and generate a result, and then to convert the result back to the first radix representation. |
