A real-time operating system (RTOS) is an operating system (OS) intended to serve real-time application process data as it comes in, typically without buffering delays. Processing time requirements (including any OS delay) are measured in tenths of seconds or shorter.
A key characteristic of an RTOS is the level of its consistency concerning the amount of time it takes to accept and complete an application's task; the variability is jitter. A hard real-time operating system has less jitter than a soft real-time operating system. The chief design goal is not high throughput, but rather a guarantee of a soft or hard performance category. An RTOS that can usually or generally meet a deadline is a soft real-time OS, but if it can meet a deadline deterministically it is a hard real-time OS.
An RTOS has an advanced algorithm for scheduling. Scheduler flexibility enables a wider, computer-system orchestration of process priorities, but a real-time OS is more frequently dedicated to a narrow set of applications. Key factors in a real-time OS are minimal interrupt latency and minimal thread switching latency; a real-time OS is valued more for how quickly or how predictably it can respond than for the amount of work it can perform in a given period of time.

Yeah, yeah, P-P-5-D

[Black Thought]
Yo! On these seventy-three keys, of ivory and ebony
I swear solemnly that I'll forever rock steadily
People wanna know where Malik? He right next to me
The weaponry, the secret recipe
Hard to peep this, deep shit, shows I eat with
Contaminated thoughts I walk the street with
I bayonnet cassettes and chop beats with
this olympic lyricism you can't, compete with
Globe travellin, throwin your verse like a javelin
Things Fall Apart and MC's unravellin
Backstage whisperin to management like
"change the order, it's no way that we can rock after them"
My man sport the 'fro like _What's Happenin?_
From the latest hi-atus, The Roots back again
Your crew practicin to catch this natural blend
They packages read "care when handlin"
It's all soft shit, batteries not included with
Matter of fact, your whole front's a re-enactment
I blow your ba-tty ass into fragments, P-5-D
The new testament, mic specialist, what?
Yeah
Check it out, yo [3X]

The Milli-illitant-tant, 'pon cock, ready to rock
Power out, in the clout, it seems out, all through your block
Posse don't play the cut, but what, you get sheist
Got the personality named trife, ready to heist
Smashin 'graphs, snatch the ice, crush your mental device
Thought twice, shoulda thought once, got played for the dunce
Dialogues I moderate, cool out, we outta state
Just blendin in the great, give me room to ventilate
Most niggaz is fraudulent, the rap seargeant
Bargin, through your regiment, call your president
Hittin all targets cuz it's a cause that's lost
Between the killers when they probably Teddy Ruxpin talk
Droppin tears of steel, two drops up in the bucket
Facin three ? and a cop so yo fuck it
If I get abducted, trapped up in the belly
Wacked up my celly, get known like Dawn Stanley
You know the deally on the daily in the ?
If I sense you got a bend to your kite, then send it up
We press up on your corner with windows they're tinted up
Lay our props face down on the ground and get it up, what?
Face on the ground and get it up

While you pose for pictures, I'm the invisible enigma
Down low, scope you off the roof like the fiddler
Cage you up in the vocal booth, you're held prisoner
Watch, while I'm bangin out this hot shit from Sigma
Illa-del-P-A, live without a DJ
And it's been that way, since Sergio Vallente
Yo, The Roots holdin it down, is all you can say
Plus the Black Thought em-cey, professional-lay
Push pen to paper like Chinua Achebe
Thumpin, what was your assumption
I lace your function, make it a Black Thought production
Word up I'm on somethin, stellar hold off course
I'm gone bluntin, travel light and broadcast
via satellite, Illa-Fifth Dynamite
Lyrically calculus in this arithametic hip-hop metropolis
But loyal fiends coppin this hot shit
Yaknahmsayin? Hot shit, word up
Illa-Fifth hot shit y'all
