There are 6 general purpose registers in processor, i. Each register can hold 8-bit data. It is a bit register used to store the memory address location of the next instruction to be executed. Microprocessor increments the program whenever an instruction is being executed, so that the program counter points to the memory address of the next instruction that is going to be executed. It is an 8-bit register having five 1-bit flip-flops, which holds either 0 or 1 depending upon the result stored in the accumulator. It is an 8-bit register. When an instruction is fetched from memory then it is stored in the Instruction register.

A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit , or a small number of integrated circuits. The microprocessor is a multipurpose, clock -driven, register -based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory , and provides results also in binary form as output. Microprocessors contain both combinational logic and sequential digital logic. Microprocessors operate on numbers and symbols represented in the binary number system. Integrated circuit processors are produced in large numbers by highly automated metal-oxide-semiconductor MOS fabrication processes , resulting in a relatively low unit price.

The first invention of the integrated circuit was in the year and this commemorated the history of microprocessors. And the first microprocessor that was invented was Intel in the year It is even termed as a central processing unit CPU where multiple computer peripheral components are integrated on one chip. This includes registers, a control bus, clock, ALU, a control section, and a memory unit. Passing many generations, the current generation of the microprocessor was able to perform high computational tasks that use bit processors also. This is a brief evaluation of microprocessors and the one type which we are going to discuss today is the microprocessor Architecture.

Защитник Джорджтауна перехватил опасную передачу, и по трибунам пронесся одобрительный гул. Сьюзан наклонилась к Дэвиду и шепнула ему на ухо: - Доктор. Он смотрел на нее с недоумением. - Доктор, - повторила. - Скажи первое, что придет в голову. - Ассоциативный ряд? - по-прежнему недоумевал Дэвид.
