![]() ![]() It performs program execution in 3 stages, which are fetching, decoding and executing.įirstly, fetching of instruction from the memory is done and then is stored in the instruction register. Also, the output of the operation is stored in the accumulator and in accordance with the outcome generated, the flags get set and reset. This means that the data during operation reside in the accumulator and temporary registers. ![]() The arithmetic and logic unit of 8085 microprocessor is able to perform operations like add, subtract, compare, complement, increment, decrement, shift, AND, OR, X-OR. More specifically we can say that as one data byte is stored in one memory location, therefore overall 64 kilobytes of data can be stored by 8085 microprocessor. Thus the permissible accessible memory space is 64KB. It offers a data bus size of 8-bit with an address bus of 16-bit. Basically, it is called so because the ALU size is of 8-bit. Content: 8085 Vs 8086Ĩ085 is an 8-bit microprocessor that is able to perform an operation on 8-bit data in a single cycle. In this section, we will discuss the other differences between 80 microprocessor using a comparison chart. There exist various other factors that create significant differences between 80 microprocessor.
