WebApr 8, 2024 · Thus, an 8086 micro-instruction typically does two things in parallel: the move and the action. For more about 8086 microcode, see my microcode blog post. ... The RCL … WebThere is only really one difference between the shift and rotate instructions: rotate cycles the bits around going out one side and coming in the other, while shift rotates the bits out one side or the other leaving the space where the rotated bits where either unchanged or zeroed. rl. rla. rlc. rlca.
WebThe 8086 does not mask the rotation count. However, all other IA-32 processors (starting with the Intel 286 processor) do mask the rotation count to 5 bits, resulting in a maximum count of 31. This masking is done in all operating modes (including the virtual-8086 mode) to reduce the maximum execution time of the instructions.
