1) The document discusses the evolution of microprocessors from their invention in 1971 to present day. It outlines the four generations of microprocessors, describing the earliest 4-bit processors of the first generation in 1971-1972 and the development of 8-bit, 16-bit, 32-bit, and now 64-bit processors through subsequent generations. 2) It provides details of a course on microcontrollers and microprocessors taught by Prof. Dipak Mahurkar, including recommended textbooks and references as well as guidelines for continuous internal assessment consisting of tests and a self-learning activity. 3) The course material covers the introduction to 80386 microprocessors in the first unit and evaluations will be based on tests of specific

2. Evolution of Microprocessors
• Transistor was invented in 1948 (23 December 1947 in Bell
lab). IC was invented in 1958 (Fair Child Semiconductors) By
Texas Instruments J Kilby. The first microprocessor was
invented by INTEL(INTegrated ELectronics).
• Size of the microprocessor – 4 bit

• Generations of microprocessors:
• First-generation –
From 1971 to 1972 the era of the first generation came which brought microprocessors like INTEL
4004 Rockwell international PPS-4 INTEL 8008 etc.
• Second generation –
The second generation marked the development of 8-bit microprocessors from 1973 to 1978.
Processors like INTEL 8085 Motorola 6800 and 6801 etc came into existence.
• Third generation –
The third generation brought forward the 16-bit processors like INTEL 8086/80186/80286 Motorola
68000 68010 etc. From 1979 to 1980 this generation used the HMOS technology.
• Fourth generation –
The fourth-generation came into existence from 1981 to 1995. The 32-bit processors using HMOS
fabrication came into existence. INTEL 80386 and Motorola 68020 are some of the popular
processors of this generation.
• Fifth-generation –
From 1995 till now we are in the fifth generation. 64-bit processors like PENTIUM, Celeron, dual,
quad, and octa-core processors came into existence.
