AMD64 Technology 26568—Rev. 3.05—September 2003 Exceptions Exception Real Invalid opcode, #UD X 260 PMINSW Virtual 8086 Protected Cause of Exception X X The SSE instructions are not supported, as indicated by bit 25 in CPUID standard function 1. 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. X X X 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 A 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.
26568—Rev. 3.05—September 2003 AMD64 Technology PMINUB Packed Minimum Unsigned Bytes Compares each of the packed 8-bit unsigned integer values in the first source operand with the corresponding packed 8-bit unsigned integer value in the second source operand and writes the numerically lesser of the two values for each comparison in the corresponding byte of the destination (first source). The first source/destination operand is an XMM register and the second source operand is another XMM register or 128-bit memory location. Mnemonic Opcode Description PMINUB xmm1, xmm2/mem128 66 0F DA /r Compares packed unsigned 8-bit integer values in an XMM register and another XMM register or 128-bit memory location and writes the lesser value of each comparison in the destination XMM register.
