Solution

The Floating Point (FP) immediate in x86 Instruction Set Architecture (ISA) can be loaded by storing its hexadecimal representation in the memory and using the FILD (Floating Point Load Integer) instruction.

Here are the steps:

  1. Store the hexadecimal representation of the FP immediate in memory. This is typically done using a MOV instruction to move the value into a memory location.

  2. Use the FILD instruction to load the value from memory into the floating-point register stack. The FILD instruction converts the integer value in memory into a floating-point value and pushes it onto the register stack.

Please note that storing the FP immediate's hexadecimal representation in Integer Registers and using the FILD instruction is not possible because FILD instruction operates on memory, not on registers.
