Title: System for adding/subtracting single precision absolute value
Inventor: MASHIMA SAKAE
IPC: G06F7/50
Filed: 1989-05-25
Abstract: PURPOSE:To speed up an arithmetic unit by inputting two operands of precision in an absolute value addition/subtraction instruction to a high-order digit and a low-order digit in double precision at an odder, attaining addition/subtraction, selecting one whose result is positive among the high-order digit and the low- order digit in an obtained operation result and setting the addition/subtraction of the absolute value in single precision to be the operation result. CONSTITUTION:The operand OP1 and the operand OP2 with single precision widths are respectively inputted to the high-order digit and the low-order digit in double precision in one input of the adder 1 with a double precision width, and the operand OP2 and the operand OP1 with the double precision widths are inputted to the high-order digit and the lower-order digit in double precision to attain addition/subtraction. Then, one whose result is positive is selected among the high-order digit and the low-order digit in the obtained result and it is set to be the operation result of the addition/subtraction of the absolute value in single precision. Thus, the addition/subtraction of the absolute value in single precision is attained only by one operation cycle, and the arithmetic unit can be speeded up.
