- Notes on the Pentium’s microcode circuitry (righto.com)
Most people think of machine instructions as the fundamental steps that a computer performs. However, many processors have another layer of software underneath: microcode. With microcode, instead of building the processor’s control circuitry from complex logic gates, the control logic is implemented with code known as microcode, stored in the microcode ROM. To execute a machine instruction, the computer internally executes several simpler micro-instructions, specified by the microcode. In this post, I examine the microcode ROM in the original Pentium, looking at the low-level circuitry.

MEKBUDA (Zeta Geminorum). More widely known as the Zeta star in Gemini (Zeta Geminorum), the Arabic name Mekbuda refers to “lion’s paw,” a larger Arabic figure that overlaid our constellations, and at one time may have more referred to one of Gemini’s luminaries Castor or Pollux.
