I'm looking at some practice code for assembly, and the assignment is basically to replace one jump point with another. The original jmp is a SHORT jmp, and th
I keep seeing people claim that the MOV instruction can be free in x86, because of register renaming. For the life of me, I can't verify this in a single tes
I'm developing my own bare-metal hypervisor over intel vt-x technology. My goal is to make it inaccessible to the OS I'm running over my hypervisor in any way,
I have to add two 3*3 arrays of words and store the result in another array. Here is my code: .data a1 WORD 1,2,3 WORD 4,2,3 WORD 1,4,3 a2 WORD 4, 3, 8

I watched a youtube video on the Top 10 Craziest Assembly Language Instructions and some of these instructions have no obvious application to me. What's the poi
Which logical processor belongs to the P-core group and which to E-core group? My first idea was to just check the base clock for each logical processor and the
In x86 assembly, is it possible to clear the Parity Flag in one and only one instruction, working under any initial register configuration? This is equivalent
