Hi friends do you know that today we are exploiting the advance technology used in our mobiles phones, smart phones and the technology due to which the computer is present in every home today is because of the a revolutionary thought in the small semiconductor company Intel Corporation for the making of a general purpose programmable device based on an instruction set.It could be programmed and the program can be easily executed using some other components and ICs. It was called Intel 4004 microprocessor. It uses a RAM memory, ROM memory, Keypad interface ICs, Latches ,etc. It occupy very less space as compared to the other computers hardware used in early days. It was like a CPU in computers on a small chip. It make the size of computers very less when its new and upgraded version started to manufacturing. It laid the foundation of most popular x86 instruction set for future products and it is most common in all intel CPUs. Today mobile phones uses a RISC (Reduced Instruction Set Computer) like ARM cortex processors whose architecture is completely different then conventional processors.
The 8051 also incorporates the basic or primitive version of x86 Architecture and it is more fun to learn about this Microcontroller. I will be updating this article from time to time so stay tuned.
