- Buryatia (Russian: Бур́ятия boor-YAH-tee-yuh) is a republic in Eastern Siberia. Aside from its cultural attractions and capital, Buryatia is a nature lover’s paradise. Almost 80% of the territory is covered by mountains, and more than half the shore-line of Lake Baikal falls under Buryatia’s jurisdiction. Outside the capital Ulan Ude, the major tourist attractions include hot springs, Lake Baikal and Mongolian-style Buddhist monasteries.
- 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.
