Rotate Instruction in 8086 with example

Web8086 Microprocessor Architecture. There are seven addressing modes in 8086 processor. Now, we will discuss all of them in detail with example assembly instructions. 1. Register addressing mode. This mode involves the use of registers. These registers hold the operands. This mode is very fast as compared to others because CPU doesn’t need to ... Web16. The SAR Instruction, Shift Arithmetic Right. Same as SHR, except that most-significant bit (MSB) is shifted back to itself. This preserves the original sign of the destination operand, because MSB is the sign bit . Each shift divides the destination operand by 2, while preserving the sign. Note that LSB is shifted into the carry flag CF . cta 9 bus https://balzer-gmbh.com

WebWorking of RCL and ROL Instruction has been discussed in this video. WebIn computer processors the carry flag (usually indicated as the C flag) is a single bit in a system status register/flag register used to indicate when an arithmetic carry or borrow has been generated out of the most significant arithmetic logic unit (ALU) bit position. The carry flag enables numbers larger than a single ALU width to be added/subtracted by carrying …
