- Reverse-engineering the conditional jump circuitry in the 8086 processor (righto.com)
Intel introduced the 8086 microprocessor in 1978 and it had a huge influence on computing. I’m reverse-engineering the 8086 by examining the circuitry on its silicon die and in this blog post I take a look at how conditional jumps are implemented. Conditional jumps are an important part of any instruction set, changing the flow of execution based on a condition. Although this instruction may seem simple, it involves many parts of the CPU: the 8086 uses microcode along with special-purpose condition logic.

Larsa (Sumerian: ššš , romanized: UD.UNUGKI, read Larsamki), also referred to as Larancha/Laranchon (Gk. ĪĪ±ĻĪ±Ī³ĻĻĪ½) by Berossos and connected with the biblical Ellasar, was an important city-state of ancient Sumer, the center of the cult of the sun god Utu with his temple E-babbar. It lies some 25 km (16 mi) southeast of Uruk in Iraq’s Dhi Qar Governorate, near the east bank of the Shatt-en-Nil canal at the site of the modern settlement Tell as-Senkereh or Sankarah.
