WebWe’ll start with the standard example I always use: lsl.b #$02,d0. This will shift the byte of d0, 02 bits to the left. Now, we’ll pretend that d0 contains 000004B2 in this example, and since it’s a byte, only the B2 is change. B2 in binary is: 1011 0010. After shifting the bits left by 02, we get: < 1100 1000 <.

Shift a 0 in as least significant bit and remember the highest bit in the Carry flag. Then for the subsequent higher bytes, you want a ROL – Rotate Left trough Carry.

WebTo multiply a sixteen bit number by two, we first LSL the lower byte, then ROL the high byte, this has the net effect of "rolling" the high bit of the lower byte into the first bit of the 2nd... WebIf the descriptor has a page granular segment limit (the granularity flag is set to 1), the LSL instruction will translate the page granular limit (page limit) into a byte limit before loading it into the destination operand. The translation is performed by shifting the 20-bit “raw” limit left 12 bits and filling the low-order 12 bits with 1s.

Web23 sep. 2012 · 4. When using the MUL opcode, there are three different results: 8 bit - results are stored in ax. 16 bit - results are stored in dx:ax. 32 bit - results are stored in edx:eax. So when you perform your multiplication, the instruction overwrites dx with zero in your case. This means that each subsequent use of the mul opcode is multiplying by zero. Web8 feb. 2024 · LSL R0, R1, R2 Logical Shift Right (LSR) Logical Shift Right (LSR) works in the reverse fashion as LSL and effectively divides a value by two. The most significant bits are filled with zeros, and the last least significant bit is put into the carry flag. LSR R0, R1, #2 Arithmetic Shift Right (ASR)

ROR … Web2 jun. 2024 · Arithmetic shift left ( ASL) is the same as logical shift left, and rotate left ( ROL) is the same as right rotation by 32 − #imm. On the other hand RLX truly is missing. But then again, who cares? I have no idea who would ever use RRX anyway. The assembly syntax separates offset from the the scale with a comma, which looks a bit odd.
