- The Pentium contains a complicated circuit to multiply by three (righto.com)
In 1993, Intel released the high-performance Pentium processor, the start of the long-running Pentium line. I’ve been examining the Pentium’s circuitry in detail and I came across a circuit to multiply by three, a complex circuit with thousands of transistors. Why does the Pentium have a circuit to multiply specifically by three? Why is it so complicated? In this article, I examine this multiplier—which I’ll call the ×3 circuit—and explain its purpose and how it is implemented.
- Psalm 137 (Wikipedia)
Psalm 137 is the 137th psalm of the Book of Psalms, beginning in English in the King James Version: “By the rivers of Babylon, there we sat down”. The Book of Psalms is part of the third section of the Hebrew Bible, and a book of the Christian Old Testament. In the slightly different numbering system used in the Greek Septuagint and Latin Vulgate translations of the Bible, this psalm is Psalm 136. In Latin, it is known by the incipit, “Super flumina Babylonis”. The psalm is a communal lament about remembering Zion, and yearning for Jerusalem while dwelling in exile during the Babylonian captivity.
