Cinema Special: Anything on Cinema | | VLSI any one ?? | |
| PS::: this post of vlsi is aimed at ppl who do not know anything abt vlsi. further we can upgrade this post into specific doubts and job opportunities etc etc
PS1: a small request to the admin. mistakenly i have posted this in anything on cinema forum. is it possible that i can move it to software central or education and entrances forum
thx,
2nd chapter on vlsi
vlsi is nothing but the design of chips. ppl might have seen some small black rectangular or square pieces inside ur mobiles or radios or transistors etc etc in every present day electronic goods. they are called as chips (do not confuse urselves with potato chips or yam chips or banana chips J ).
in today's post we will know the lifecycle of these chips.
any product will start with a design idea. this design idea is put into major blocks and each major block will stand for a specific functionality that has to be performed. we can better understand this functionality if we consider an example. let's take a real life example. let's say we all want to go to a picnic. going to a picnic is a basic design idea. now to organize a picnic and actually implementing it will cover a lot of other issues like where to go, how to go, what to take there, what are allowed there, and how much time to spare, whether we are progressing according to the schedule or not etc etc. we can see each issue as a different functionality. means in our picnic case, we have where to go block, when to go block, how to go block, what to take there block, who will come block, etc.
now each block will be again sub-divided into multiple sub blocks. if we take where to go block, this can be divided into whether to a beach resort or to a cinema or to a hill station or to a temple or to a village etc. and again these subdivied blocks are further subdivied into micro modules until we come to a stage where in further division is not possible.
similarly any design idea is divided into subblocks until further division is not possible. this is called top down approach.
now after division of a big block into a sub block, the actual design starts.
the actual design how it is done, other steps in design will be explained in the next post

VLSI --> Very Large Scale Integration as it stands for is a recent branch of science which sprang up into existence after the invention of a diode.
as the name suggests, VLSI is nothing but embedding many functions (or clubbing many features)onto a single board for effective usage of space, targetting speed and acheiving more reliabiliy.
a basic and crude example of vlsi is as under:
an old murphy radio used to come in a pack as big as a modern microwave oven. but now it is coming even in cell phones. may be in the near future it may come in wrist watches also. so many operations that the old radio used to do is done in simple and compact space. this is nothing but vlsi. infact, vlsi ppl can be called as packers and movers !! they pack multiple functionalities into a single chip.
this is a simple explanation of vlsi. iwill go into more details tomorrow

hey all,
i plan to start a new post on vlsi. i had already started it once, but could not get a proper response. so wanted to restart it again with new vigour.
any persons in the field of vlsi can participate.
