What is the “FS”/“GS” register intended for?
...if one is willing to round memory allocations up to multiples of 16 bytes, 8086-style segmentation allows one to use the segment alone as a means of identifying an object. Rounding allocations up to 16 bytes might have been slightly irksome in 1980, but would represent a win today if it reduced the...

Purpose of memory alignment
...g study of the tradeoffs between speed and cost, it was basically a 16-bit 8086 (which had a full 16-bit external bus) but with only half the bus-lines to save production costs. Because of this the 8088 needed twice the clock cycles to access memory than the 8086 since it had to do two reads to get ...

Why is x86 ugly? Why is it considered inferior when compared to others? [closed]
...ssible reasons for it:
x86 is a relatively old ISA (its progenitors were 8086s, after all)
x86 has evolved significantly several times, but hardware is required to maintain backwards compatibility with old binaries. For example, modern x86 hardware still contains support for running 16 bit code na...
Simulator or Emulator? What is the difference?
... result/outcome is always the same as the original object. For example, EMU8086 emulates the 8086 microprocessor on your computer, which obviously is not running on 8086 (= different protocols), but the output it gives is what a real 8086 would give.
