The programming Model of 8085 Microprocessor
The programming model of 8085 microprocessor is shown in figure below in this model various 8 bit and 16 bit registers are shown. Registers are actually a set of flip flops. Registers are used to store data temporarily for processing. Enormous data is stored in memory which is on a separate chip hence more time is consumed to access data from memory by the microprocessor. Therefore the data which need processing are copied into registers within microprocessor to save processing time.
