In SHLD instruction, first 3 cycle is same as in described in LHLD instruction. Number of bytes used in instruction:- 3 bytes Total no. of. 15. SHLD -- Double Precision Shift Left. Opcode Instruction Clocks Description 0F A4 SHLD r/m16,r16,imm8 3/7 r/m16 gets SHL of r/m16 concatenated with r16 0F A4 SHLD/SHRD - Double Precision Shift (386+) Usage: SHLD dest,src,count SHRD dest,src,count Modifies flags: CF PF SF ZF (OF,AF undefined) SHLD shifts dest to Opcode. Instruction. Description. 0F A4. SHLD r/m16, r16, imm8. Shift r/m16 to left imm8 places while shifting bits from r16 in from the right. 0F A5. shld double-precision left shifts a 16- or 32-bit register value into a word or long for the count specified by an immediate value, MODULO 32 (0 to 31).SHLD/SHRD - Double Precision Shift (386+) Usage: SHLD dest,src,count Computers are not base 10 the very very old base 10 instructions Basically SHLD instruction is paired with a 16 bit memory location ,which means that the data of the mentioned memory location is stored in L-register & the
