- 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.

Yellowknife (/ˈjɛloʊnaɪf/; Dogrib: Sǫǫ̀mbak’è) is the capital, largest community, and only city in the Northwest Territories, Canada. It is on the northern shore of Great Slave Lake, about 400 km (250 mi) south of the Arctic Circle, on the west side of Yellowknife Bay near the outlet of the Yellowknife River.
