- Algeria has known many empires and dynasties, including the ancient Numidians (3rd century B.C.), Phoenicians, Carthaginians, Romans, Vandals, Byzantines, over a dozen different Arab and Amazigh dynasties, Spaniards, and Ottoman Turks. Under the Turks, the Barbary pirates operated from North Africa and preyed on shipping, from about 1500 until the French captured Algiers in 1830. The French southward conquest of Algeria proceeded throughout the 19th century and was marked by many atrocities. A bloody eight-year struggle culminated in Algerian independence in 1962.
- How the 8086 processor determines the length of an instruction (righto.com)
The Intel 8086 processor (1978) has a complicated instruction set with instructions ranging from one to six bytes long. This raises the question of how the processor knows the length of an instruction.1 The answer is that the 8086 uses an interesting combination of lookup ROMs and microcode to determine how many bytes to use for an instruction. In brief, the ROMs perform enough decoding to figure out if it needs one byte or two. After that, the microcode simply consumes instruction bytes as it needs them. Thus, nothing in the chip explicitly “knows” the length of an instruction. This blog post describes this process in more detail.
