Vector multiplication with operand base system conversion and re-conversion

A machine readable medium containing program code that when processed by a processor cause a method to be performed, said method comprising:

• multiplying two vectors by:
• receiving a vector element multiplicand and vector element multiplier expressed in a first base system;
• converting said vector element multiplicand and vector element multiplier into a second lower base system to form a converted vector element multiplicand and a converted vector element multiplier;
• multiplying said converted vector element multiplicand and said converted vector element multiplier to form a multiplication result;
• accumulating a portion of said multiplication result with a portion of a result of a prior multiplication of operands expressed in said second lower base system;
• converting contents of said register into said first base system.

A computer system having stored program code that when processed by a processor of said computer system causes a method to be performed, said method comprising:

• multiplying two vectors by:
• receiving a vector element multiplicand and vector element multiplier expressed in a first base system;
• converting said vector element multiplicand and vector element multiplier into a second lower base system to form a converted vector element multiplicand and a converted vector element multiplier;
• multiplying said converted vector element multiplicand and said converted vector element multiplier to form a multiplication result;
• accumulating a portion of said multiplication result with a portion of a result of a prior multiplication of operands expressed in said second lower base system;
• converting contents of said register into said first base system.
