AMD 64-Bit Technology 26568—Rev. 3.02—August 2002 RCPPS Reciprocal Packed Single-Precision Floating-Point Computes the approximate reciprocal of each of the four packed single-precision floating-point values in an XMM register or 128-bit memory location and writes the result in the corresponding doubleword of another XMM register. The rounding control bits (RC) in the MXCSR register have no effect on the result. The maximum relative error is less than or equal to 1.5 * 2 –12 . A source value of 0.0 returns an infinity of the source value’s sign. Denormal source operands are treated as signed 0.0. Results that underflow are changed to signed 0.0. For both SNaN and QNaN source operands, a QNaN is returned. Mnemonic Opcode Description RCPPS xmm1, xmm2/mem128 0F 53 /r Computes reciprocals of packed single-precision floating-point values in an XMM register or 128-bit memory location and writes result in the destination XMM register. xmm1 xmm2/mem128 127 96 95 64 63 32 31 0 127 96 95 64 63 32 31 0 reciprocal reciprocal reciprocal reciprocal rcpps.eps Related Instructions RCPSS, RSQRTPS, RSQRTSS rFLAGS Affected None 342 RCPPS

X X X The emulate bit (EM) of CR0 was set to 1. X X X The operating-system FXSAVE/FXRSTOR support bit (OSFXSR) of CR4 is cleared to 0. Device not available, #NM X X X The task-switch bit (TS) of CR0 was set to 1. Stack, #SS X X X A memory address exceeded the stack segment limit or was non-canonical. General protection, #GP X X X A memory address exceeded a data segment limit or was non-canonical. X A null data segment was used to reference memory. X X X The memory operand was not aligned on a 16-byte boundary. Page fault, #PF X X A page fault resulted from the execution of the instruction. RCPPS 343
