What is ULSI microprocessor?
What is ULSI microprocessor?
Ultra large-scale integration (ULSI) is the process of integrating or embedding millions of transistors on a single silicon semiconductor microchip. ULSI technology was conceived during the late 1980s when superior computer processor microchips, specifically for the Intel 8086 series, were under development.
Who invented ULSI?
Sir John Ambrose Fleming (1849–1945) was usually considered the scientist who invented vacuum tube diodes; he was a prominent English scien- tist and he got US Patent 803,684 in 1905 for this invention.
What is the full form of ULSI in computer?
(Ultra Large Scale Integration) An earlier measurement of transistor density on a chip. ULSI was more than one million transistors, which today is commonplace.
What is the generation of ULSI?
the fifth generation
In the fifth generation, VLSI technology became ULSI (Ultra Large Scale Integration) technology, resulting in the production of microprocessor chips having ten million electronic components. This generation is based on parallel processing hardware and AI (Artificial Intelligence) software.
What is after ULSI?
Moletronics is the latest technology after ULSI technology & it performs by using molecules to make electronic components work like transistors, diodes, logic gates, etc. For the fabrication of active & passive components, molecular building blocks are used like resistors & transistors.
Which generation uses the ULSI technology?
fifth generation of computers
The main characteristics of fifth generation of computers (the present and the future) Main electronic component: based on artificial intelligence, uses the Ultra Large-Scale Integration (ULSI) technology and parallel processing method.
When was ULSI invented?

LSI | large-scale integration | 1971 |
VLSI | very large-scale integration | 1980 |
ULSI | ultra-large-scale integration | 1984 |
How many transistors are in ULSI?
1 000 000

LSI | large-scale integration | 500 to 20 000 |
VLSI | very large-scale integration | 20 000 to 1 000 000 |
ULSI | ultra-large-scale integration | 1 000 000 and more |
What is MSI and LSI?
– The next step in the development of integrated circuits, introduced devices which contained hundreds of transistors on each chip, called “medium-scale integration” (MSI). – Further development, driven by the same economic factors, led to “large-scale integration” (LSI, with tens of thousands of transistors per chip.
What came after VLSI?
Terms suggesting greater than VLSI levels of integration are no longer in widespread use. In 2008, billion-transistor processors became commercially available. This became more commonplace as semiconductor fabrication advanced from the then-current generation of 65 nm processes.
Are 4th generation of computers made with pics of ULSI technology?
The main Characteristics of the fourth generation computers are: Technology used: ULSI technology being used. Parallel processing hardware and artificial intelligence is used. Robotics, neural networks, Expert systems, game playing and natural languages all are included in fifth generation.
