Shift Instructions. The 8086 can perform two types of Shift operations; the logical shift and the arithmetic shift. There are four shift operations (SHL,
Instructions to perform shift operations · SHL/SAL − Used to shift bits of a byte/word towards left and put zero(S) in LSBs. · SHR − Used to shift bits of a
The SAR and SHR instructions can be used to perform signed or unsigned division, respectively, of the destination operand by powers of 2. For example, using
sar right shifts (signed divides) a byte, word, or long value for a count specified by an immediate value and stores the quotient in that byte, word, or long
4- Shift instruction: Shift instructions of the 8086 can perform two basic types of shift operations; the logical shift and the arithmetic shift.
The Shift Instructions in 8086 are follows SAL/SHL SHR SAR SAL/SHL Instruction : SAL/SHL destination, count. SAL and SHL are two mnemonics.
16. The SAR Instruction, Shift Arithmetic Right · Same as SHR, except that most-significant bit (MSB) is shifted back to itself. · This preserves the original

SAL (or its synonym, SHL) shifts the bits of the operand upward. The high-order bit is shifted into the carry flag, and the low-order bit is set to 0. SAR and

For example, using the SAR instruction to shift a signed integer 1 bit to the This masking is done in all operating modes (including the virtual-8086
For example, the shl instruction shifts the bits in the destination For 8088 and 8086 CPUs, the number of bits to shift is either “1” or the value in cl
