- Christian universalism is a school of Christian theology focused around the doctrine of universal reconciliation – the view that all human beings will ultimately be saved and restored to a right relationship with God. “Christian universalism” and “the belief or hope in the universal reconciliation through Christ” can be understood as synonyms. Opponents of this school, who hold that eternal damnation is the ultimate fate of some or most people, are sometimes called “infernalists.”
- Silicon reverse-engineering: the Intel 8086 processor’s flag circuitry (righto.com)
Status flags are a key part of most processors, indicating if an arithmetic result is negative, zero, or has a carry, for instance. In this post, I take a close look at the flag circuitry in the Intel 8086 processor (1978), the chip that launched the PC revolution.1 Looking at the silicon die of the 8086 reveals how its flags are implemented. The 8086’s flag circuitry is surprisingly complicated, full of corner cases and special handling. Moreover, I found an undocumented zero register that is used by the microcode.
