The instruction set of the 8051 family is directly related to a special function register called program status word (PSW). This special function register is able to provide the conditions of the processing of the last instruction performed, which is capable of changing it (only some instructions...

There are few electrical engineers these days who do not regularly interact, at least indirectly, with embedded processors. Almost any design can benefit from the presence of a small microcontroller and, in many cases, there is need for a powerful microcontroller, a digital signal processor, or...
This paper proposes simple instruction level energy estimation for 8051 microcontroller based system for undergraduate level students. Energy estimation is very much important for any embedded system operating on battery. The measurement of the power associated with each instruction is carried out. Once ...
