Microprocessor 8085

The microprocessor is a high-speed integrated circuit used in many domains to perform specific tasks. These tasks are interpreted by a particular language called "Mnemonic." This language is based on the abbreviation of instructions defined by the constructor as mnemonic codes. The present course provides the external and internal architecture of the 8085 microprocessor. First, an overview of the aspects of microprocessors will be tackled. Following, an essential phase will be evoked, which is resumed in the elaboration of an assembly program based on mnemonic codes by providing some famous examples. But before this step, we will study the different groups of instructions that rely on the 8085 microprocessor.
