Zero - We Dont Care

If we go through traditional design, we can take advantage of these "don't cares" and assign to them the most convenient values so the resulting equations (and hence, the circuit) are the most simple ones. For example, we could change the previous truth table into this one:

Zero - We Dont Care

For this example, I've been able to make optimizations by hand, but consider a controller module with dozen of outputs to a datapath module. There could be output signals from the controller that may have a don't care value for a given state of the controller.

In digital logic, a don't-care term[1][2] (abbreviated DC, historically also known as redundancies,[2] irrelevancies,[2] optional entries,[3][4] invalid combinations,[5][4] vacuous combinations,[6][4] forbidden combinations,[7][2] unused states or logical remainders[8]) for a function is an input-sequence (a series of bits) for which the function output does not matter. An input that is known to never occur is a can't-happen term.[9][10][11][12] Both these types of conditions are treated the same way in logic design and may be referred to collectively as don't-care conditions for brevity.[13] The designer of a logic circuit to implement the function need not care about such inputs, but can choose the circuit's output arbitrarily, usually such that the simplest circuit results (minimization).

"Don't care" may also refer to an unknown value in a multi-valued logic system, in which case it may also be called an X value or don't know.[16] In the Verilog hardware description language such values are denoted by the letter "X". In the VHDL hardware description language such values are denoted (in the standard logic package) by the letter "X" (forced unknown) or the letter "W" (weak unknown).[17]

Further considerations are needed for logic circuits that involve some feedback. That is, those circuits that depend on the previous output(s) of the circuit as well as its current external inputs. Such circuits can be represented by a state machine. It is sometimes possible that some states that are nominally can't-happen conditions can accidentally be generated during power-up of the circuit or else by random interference (like cosmic radiation, electrical noise or heat). This is also called forbidden input.[18] In some cases, there is no combination of inputs that can exit the state machine into a normal operational state. The machine remains stuck in the power-up state or can be moved only between other can't-happen states in a walled garden of states. This is also called a hardware lockup or soft error. Such states, while nominally can't-happen, are not don't-care, and designers take steps either to ensure that they are really made can't-happen, or else if they do happen, that they create a don't-care alarm indicating an emergency state[18] for error detection, or they are transitory and lead to a normal operational state.[19][20][21]

In life, our fucks must be spent on something. There really is no such thing as not giving a fuck. The question is simply how we each choose to allot our fucks. You only get a limited number of fucks to give over your lifetime, so you must spend them with care.

Heavy metal supergroup Hellyeah released a cover of I Don't Care Anymore as a single on July 27, 2016 off their Undeniable album. The cover features a lost performance by Dimebag Darrell which was unearthed by his older brother, Hellyeah drummer Vinnie Paul. According to Paul, Damageplan's cover of the song never saw the light of day and it took him three weeks to find the recordings. The lost recordings would eventually be converted with Pro Tools with the help of producer Kevin Churko. Chad Gray called recording the vocal sessions a very emotional moment while mentioning that having the band track Dimebag Darrell's riffs was one of the most magical moments in Gray's career.[5][6][7][8] A music video for the rendition was released to Eleven Seven's YouTube channel a day after the single was released with the video being directed by William "Wombat Fire" Felch.[9][6] In an interview with Billboard, Chad Gray stated that he hopes that Phil Collins loves the band's cover of the track.[10]

After discussion's with him he said that he doesn't want to be doing this but his mind goes blank when its time to go to school and all that he does is withdraw from it and doesn't care about any consequences or how it will affect his life. It's kind of like despair. He sees his brain as someone he can't control.

"How are you?" These are the three most useless words in the world of communication. The person asking doesn't really want to know, and the person responding doesn't tell the truth. What follows is a lost opportunity and meaningless exchange with zero connection.

"When people are instructed to ask more questions, they are perceived as higher in responsiveness, an interpersonal construct that captures listening, understanding, validation and care," the researchers wrote.

The definition says that we can use a don't care as either 1 or 0. It seems that if we consider a don't care as 1, we can't consider it as 0 while computing product of sum from the same k-map. Is it true?Any explanation on this stating the actual significance of don't care would be highly appreciated.

On Thursday, First Lady Melania Trump made a surprise trip to Texas to visit immigrant children. On the plane there, Trump was pictured wearing a green military jacket that says, "I really don't care, do u?"

Trump's visit to McAllen, Texas, came amid the controversy over President Donald Trump's "zero tolerance" immigration policy that has led to children being separated from their parents at the border between the US and Mexico.

Sometimes, though, the impact is more significant. Maintaining relationships with others and paying attention to their needs can occasionally detract from your ability to take care of yourself and achieve positive self-growth.

Coach Boone : This is where they fought the battle of Gettysburg. Fifty thousand men died right here on this field, fighting the same fight that we are still fighting among ourselves today. This green field right here, painted red, bubblin' with the blood of young boys. Smoke and hot lead pouring right through their bodies. Listen to their souls, men. I killed my brother with malice in my heart. Hatred destroyed my family. You listen, and you take a lesson from the dead. If we don't come together right now on this hallowed ground, we too will be destroyed, just like they were. I don't care if you like each other of not, but you will respect each other. And maybe... I don't know, maybe we'll learn to play this game like men.

Coach Boone : Yes you can. When I was fifteen years old I lost my mother and my father in the same month Ronnie, same month. 12 brothers and sisters I was the youngest one of them, now I wasn't ready either, but they needed me. Your team needs you tonight, you're the Coronel, you're going to command your troops! Twins right 48 zero read, *go!*

• Some people are concerned because they struggle to take an interest in others and what they have to say. They'll express thoughts such as: "I just don't find most people that interesting. I know I should, but I'm just not."

• "I can't bring myself to care when a co-worker or party guest is telling me about mundane things like how their week is going or why they like some random hobby."

• "I can't be bothered to try to learn about people, because most of them are boring and generic. They don't have anything to say that I need to hear."

• "I know how to go through the motions of asking people about themselves and seeming interested, but I don't actually enjoy those conversations."

• "I don't get much from talking to people unless we're discussing one of my narrow interests."

• "I don't want to learn details about people for its own sake. I'm like, 'What's the point?' How am I benefiting by hearing about this?'"

• "I'm self-reliant and happy to be on my own. I don't need to be learning about everyone's lives all the time. "

Sometimes these views will be tinted with misanthropic feelings. More often people who think this way don't hate everyone. They just aren't internally motivated to get to know anyone better. They realize it interferes with their social life and wish they could be more interested in others, but aren't sure how to change their mentality.

If a stranger tells you about their recent car problems you'll be less likely to be interested or care. You don't know them, so why would you need to hear how one of their brakes isn't working very well? If your best friend tells you the same thing you're going to be more invested. No, you may not think it's the most engrossing tale to ever reach your ears, but it's happening to your buddy. You want to know what's going on in their life, even the routine stuff. You want things to work out for them. 041b061a72
