These instructions must wait for the FPU pipeline to flush. Cycle count depends on what instructions are in the pipe-
line.
The AMD Geode LX processor performs PFRCP and PFRSQRT to 24-bit accuracy in one cycle, so these instructions
are unnecessary. They are treated as a move.
Non-standard AMD 3DNow! instruction. See Section 8.4.1 on page 674 for details.
