Fixed point to floating point conversion

A method comprising:

• decoding an instruction having fields for an opcode, a packed data source operand identifier, and a packed data destination operand identifier;
• and
• executing the decoded instruction to convert a data element from a least significant packed data element position of the identified packed data source operand from a fixed-point representation to a floating point representation, store the floating point representation into a 32-bit least significant packed data element position of the identified packed data destination operand, and zero all remaining packed data elements of the identified packed data destination operand.

A non-transitory machine-readable medium storing an instruction which is to cause a processor to perform a method comprising:

• decoding an instruction having fields for an opcode, a packed data source operand identifier, and a packed data destination operand identifier;
• and
• executing the decoded instruction to convert a data element from a least significant packed data element position of the identified packed data source operand from a fixed-point representation to a floating point representation, store the floating point representation into a 32-bit least significant packed data element position of the identified packed data destination operand, and zero all remaining packed data elements of the identified packed data destination operand.

An apparatus comprising:

• decode means for decoding an instruction having fields for an opcode, a packed data source operand identifier, and a packed data destination operand identifier;
• and
• execution means for executing the decoded instruction to convert a data element from a least significant packed data element position of the identified packed data source operand from a fixed-point representation to a floating point representation, store the floating point representation into a 32-bit least significant packed data element position of the identified packed data destination operand, and zero all remaining packed data elements of the identified packed data destination operand.
