SHR : Shift Logical Right: This instruction performs bit-wise right shifts on the operand word or byte that might be reside in a memory location or a register, by the specified count in the instruction and inserts zeros in the shifted positions. The result is in the destination operand. Given figure describe execution of this instruction. This instruction shifts operand through the carry flag.
Figure: Execution SHR Instruction
SAR : Shift Arithmetic Right: This instruction performs right shifts on the operand byte or word that might be memory location or register by the particular count in the instruction and inserts the most significant bit of the operand in the new inserted positions. The result is in the destination operand. Given figure described execution of the instruction. All of the condition code flags are affected from this. This shift operation shifts the operand through the carry flag.
