Method and apparatus for correction of positive and negative overflow.

摘要

An apparatus is provided for correcting underflow of binary data and for correcting overflow of binary data from computation unit for producing binary data in a fixed point range comprising: detecting mechanism for detecting underflow of binary data from the fixed ponit range and for detecting overflow of binary data from the fixed point range; output mechanism for providing binary output data in the fixed point range; and inverting mechanism, responsive to said detecting mechanism, for inverting all bits of binary data produced in the fixed point range by the computation unit and for providing the inverted binary data to said output mechanism.
