The Intel 8085 is an 8-bit microprocessor introduced by Intel in 1977. It is binary-compatible with the more-famous Intel 8080 but required less supporting hardware, thus allowing simpler and less expensive microcomputer systems to be built. It requires only a 5v power supply. Interfacing can also be done with the higher versions of 8085(8051) which is specifically designed for interfacing.The only application of 8085 is that it is used in the educational institutions for study porpose.
Intel ATOM is the recently launched microprocessor. Intel ATOM is a 64 bit microprocessor and it is the world’s smallest processor as of now. Intel Atom can execute up to two instructions per cycle. Intel atom processor is used in ultra mobile pc, smart phone and other portable and low-power applications.
The educational institutions in Asia and many European countries are still following 8085. The educational institutions have 8085 in their syllabus for the past 20 years. The recently emerged microprocessor have more instuction registers than 8085. With more number of Instruction registers and Instruction sets, it is much easier to do programming and the basic Programming which will change with different instruction sets. The applications of 8085 is very limited and it is very hardly used now. The architecture of the recently emerged microprocessor is totally different from 8085. Since the architecture is different, even the hardware study will not be that much useful with 8 bits when compared to 64 bits used now. With both the programming style and the hardware architecture differing from the recently devoloped microprocessor it is better to upgrade the syllabus and introduce a 64 bit microprocessor for study so that it will be useful.
