- 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.
- The Searchers (Wikipedia)
The Searchers is a 1956 American epic Western film directed by John Ford and written by Frank S. Nugent, based on the 1954 novel by Alan Le May. It is set during the Texas–Indian wars, and stars John Wayne as a middle-aged Civil War veteran who spends years looking for his abducted niece (Natalie Wood), accompanied by his adopted nephew (Jeffrey Hunter). It was shot in VistaVision on Eastmancolor negative with processing and prints by Technicolor.
