Title: Floating-point arithmetic unit
Inventor: YOSHIOKA SHINICHI
IPC: G06F7/00
Filed: 2000-03-09
Abstract: PROBLEM TO BE SOLVED: To increase the arithmetic processing speed by predicting canceling without waiting for comparison between characteristic parts for alignment of operands. SOLUTION: In a floating-point arithmetic unit capable of quickly executing the arithmetic processing, a canceling prediction circuit 6 directly takes in operands before they pass selectors 2 and 3 and predicts canceling of the subtraction result in a subtractor 5 of operands. Consequently, canceling is predicted without waiting for selective operation of selectors 2 and 3 and alignment of operands based on comparison between characteristic parts of operands in a comparison circuit 1, and the presence or the absence of the canceling prediction error accompanied with this prediction is detected by a prediction error detection circuit 10. Canceling is predicted when or before the subtraction result is obtained from the subtractor 5 through a selector 12.  Thus, a left shifter 8 performs normalization processing of the subtraction result without delay, and an error correction shifter 9 corrects the canceling prediction error without delay by a correction signal from the prediction error detection circuit 10.
