Abstract
An apparatus comprises processing circuitry to perform a conversion operation to convert a vector comprising a plurality of data elements representing respective bit significance portions of a binary value to a scalar value comprising an alternative representation of said binary value.
Claims20
An apparatus comprising:
- processing circuitry to perform a conversion operation to convert a vector comprising a plurality of data elements representing respective bit significance portions of a binary value to a floating-point value comprising an alternative representation of said binary value;
- the processing circuitry comprising:
- exponent determining circuitry to determine an exponent of the floating-point value based on a position of a most significant non-sign bit within the plurality of data elements and a significance of the data element comprising the most significant non-sign bit;
- and
- significand determining circuitry to perform a significand generation operation to generate a partial significand value for at least one of the plurality of data elements, and to form a significand of the floating-point value based on the partial significand value generated for said at least one data element.
