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.

摘要： Apparatus for converting numbers between positive and negative radices comprising a first bistable element for providing signals representative of the odd and even orders of the number to be converted. Gating means responsive to the signals from the first bistable element and the digits of the number to be converted provides signals to the inputs of a second bistable element. An EXCLUSIVE OR logic circuit coupled to the output of the second bistable element and responsive to the digits of the number to be converted provides the converted digits of the number. Means are included to preset the first and second bistable elements to predetermined states, respectively, independently of the signs of the numbers to be converted.
