New International Version
And he dreamed yet another dream, and told it his brethren, and said, Behold, I have dreamed a dream more; and, behold, the sun and the moon and the eleven stars made obeisance to me.
Genesis 37:9 KJVThen he had another dream, and he told it to his brothers. “Listen,” he said, “I had another dream, and this time the sun and moon and eleven stars were bowing down to me.”
Genesis 37:9 NIV
- The Z-80’s 16-bit increment/decrement circuit reverse engineered (righto.com)
The 8-bit Z-80 processor was very popular in the late 1970s and early 1980s, powering many personal computers such as the Osborne 1, TRS-80, and Sinclair ZX Spectrum. It has a 16-bit incrementer/decrementer that efficiently updates the program counter and stack pointer, as well as supporting several 16-bit instructions and memory refresh. By reverse engineering detailed die photographs of the Z-80, we can see exactly how this increment/decrement circuit works and discover the interesting optimizations it uses for efficiency.
