  EVOLUTION OF MICROPROCESSOR First-generation: 1.1971 to 1972 1st gen microprocessors processed their instructions serially. 2. Fetches the instruction, decoded it, then executed it. Then fetches next instruction. Second generation: 1. By the late 1970s, enough transistors were available on the IC 2. This new technology resulted in increase in instruction, execution, speed, and higher chip densities, with the use of semi conductor technologies fabricated on the chip. Third generation: 1. In 1978, This generation of microprocessors was different from the previous ones in that all major manufacturers began developing their own RISC-based microprocessor architectures

  CONT.., Fourth generation: entered theirfourth generation with designs surpassing a million transistors Fifth generation: employed decoupled super scalar processing, and their design soon surpassed 10 million transistors. In this generation, PCs are a low-margin, high-volume-business dominated by a single microprocessor.

  MICRO PROCESSOR 1. Microprocessoris an IC which has only the CPU inside them i.e. only the processing powers such as Intel’s Pentium 1,2,3,4, core 2 duo, i3, i5 etc. 2. These microprocessors don’t have RAM, ROM, and other peripheral on the chip. 3. A system designer has to add them externally to make them functional. 4. Application of microprocessor includes Desktop PC’s, Laptops, notepads etc.
