1st Generation Microprocessor :
At the end of the 70s a group of engineers developed a chip is able to processing data. This chip was called processor chip. Big processors were developed by using VLSI technology. Another successful try of engineers, in the developing a processor which worked in a controlled manner, was called microprocessor. Thus a single VLSI/LSI/VVLSI chips are able to processing data in a controlled manner was called the microprocessor.
The design team headed by Ted Hoff of Intel Corporation developed the 1st such controlled processor in 1969, but Intel began marketing its first microprocessor in the name of Intel 4004 in the year of1971. This was a 4-bit microprocessor which have16-pins hocused in a single chip of pMOS technology. This was called the first generation of the microprocessor. The 4-bit microprocessor worked with 4-bit word .The Intel 4004 along with few other devices was used for developing calculators. The ability of changing functions of any system by only changing the programming rather than redesigning of the hardware was the key behind the growth of the microprocessors.
The Intel 8008 was developed in 1972 that worked with 8-bit word.
It required about 20 or more extra devices (chips) to design a functional CPU.
A few first generation microprocessors are listed in the Table:
implement the following c++ code in assembly language using the block-structured .IF and .while directives
You have to write a subroutine (assembly language code using NASM) for the following equation.
AAA: ASCII Adjust after Addition operation the AAA instruction is executed after an ADD instruction that adds 2 ASCII coded operands to give a byte of outcome in the AL. The AAA i

64-bit integer calculator, which processes using 16-bits at a time (reg/mem16 operands)
IInd Generation Microprocessor : The second generation microprocessor by using n MOS technology seemed in the market in 1973. The Intel 8080, of nMOS technology
Mov ax, [1234h: 4336h + 100]
DEC: Decrement :- The decrement instruction subtracts 1 from the contents of the particular memory location or register. All the conditions code flags except carry flag are affec
SBB: Subtract with Borrow :- The subtract with borrow instruction subtracts the source operand and the borrow flag (CF) which might reflect the result of the past calculations,
Example : Add the contents of the 2000H: 0500H memory location to contents of 3000H: 0600H and store the result in 5000H: 0700H. Solution : Unlike the past example progra
