Cycle-Accurate 8088 Emulation - Daniel Balsom

Despite the age and popularity of the 8088 CPU, the secrets that allowed cycle-perfect emulation were only recently unlocked. In this talk I will discuss the various reasons for why cycle-accurate emulation of the 8088 is so difficult and describe the challenges faced and techniques used to develop MartyPC.

Amazing presentation on the fascinating topic of instruction execution of the 8088. I really appreciate how he explains the approach he took to solve the problems.

Vey impressive project. Excellent presentation.

Wow. Imagine deciphering the microcode design by looking at die images (assuming I understood this correctly). What clever boys do in their spare time. Geez.

@josephfatur1747: Indeed there are very clever people doing clever things!

[@jess648]

though it’s aimed ay fellow programmers Daniel does a great job explaining how the hardware works and the quirks of its memory addressing methods in a way the layman can understand really well. I could follow along and really start to understand what made emulating it a difficult task for the longest time

@jess648: This is why it was a pleasure for him to come give a talk at our show!

I wonder if I will live enough to see the SPICE accurate sim of an old processor 😅

@thcoura: We may never know! ;)
