摘要： Apparatus and methods for conversion from floating point to signed integer representation are provided. Two's complementation and determination of a shift control signal indicating the number of bit positions for shifting the two's complemented mantissa to produce the signed integer are performed in parallel. Generation of the shift control signal, including application of an optional scaling factor, is performed using an adder, with the most significant bit of input floating point exponent inverted and an external carry-in of one. Two's complementation for generation of the signed integer from the mantissa is performed using an adder. Certain aspects may be utilized for purposes other than format conversion. The two's complementation may be used for general conversion from unsigned to signed integer format or from signed to unsigned integer format.
