The microprocessor is a very high-speed integrated circuit used in many fields to perform specific tasks. These tasks are interpreted by a specific language called "assembly." This list is based on an abbreviation of instructions given by the constructor named mnemonic codes. In the present course, the external and internal architecture of the 8085 microprocessor are detailed step-by-step. But before this last, an overview of the different aspects and concepts of microprocessors is tackled. By following, a primordial step is evoked, which is resumed in the manner of writing an assembly program based on mnemonic codes by resolving some famous examples. But before this last, we see the different groups of instructions rely on the 8085 microprocessor.
