- Aristotle (/ˈærɪˌstɒtəl/; Greek: Ἀριστοτέλης Aristotélēs, pronounced [aristotélɛːs]; 384–322 BCE) was an Ancient Greek philosopher and polymath. His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum in Athens, he began the wider Aristotelian tradition that followed, which set the groundwork for the development of modern science.
- Reverse-engineering the interrupt circuitry in the Intel 8086 processor (righto.com)
Interrupts have been an important part of computers since the mid-1950s, providing a mechanism to interrupt a program’s execution. Interrupts allows the computer to handle time-critical tasks such as I/O device operations. In this blog post, I look at the interrupt features in the Intel 8086 (1978) and how they are implemented in silicon, a combination of interesting circuitry and microcode.
