- Counting bits in hardware: reverse engineering the silicon in the ARM1 processor (righto.com)
How can you count bits in hardware? In this article, I reverse-engineer the circuit used by the ARM1 processor to count the number of set bits in a 16-bit field, showing how individual transistors form multiplexers, which are combined into adders, and finally form the bit counter. The ARM1 is the ancestor of the processor in most cell phones, so you may have a descendent of this circuit in your pocket.

Abdullah II (Abdullah bin Hussein; born 30 January 1962) is the King of Jordan, having ascended the throne on 7 February 1999. He is a member of the Hashemites, who have been the reigning royal family of Jordan since 1921, and is traditionally regarded as a 41st-generation direct descendant of the Islamic prophet Muhammad.
