My Internal IRQ is Broken

Interrupt ReQuest (IRQ) is an hardware interrupt on a PC. There are 16 IRQ lines used to signal the CPU that a peripheral event has started or terminated. Except for PCI devices, two devices cannot use the same line. If a new expansion card is preset to the IRQ used by an existing board, one of them must be changed. This was an enormous headache in earlier machines.

Starting with the Intel 286 CPU in 1982, two 8259A controller chips were cascaded together and bumped the IRQs from 8 to 16. However, IRQ 2 is lost because it is used to connect to the second chip. IRQ 9 may be available for general use as most VGA cards do not require an IRQ.

PCI to the Rescue
The PCI bus solved the limited IRQ problem, as it allowed IRQs to be shared. For example, if there were only one IRQ left after ISA devices were assigned their required IRQs, all PCI devices could share it.

Intel in the Best Position to be the Trailblazer of the Pack

After Fighting Mobile Trend, Intel Now Embraces It

As a late start contender with a powerhouse engine to produce chip innovation, they can only take their business up beyond the current established producers.  It was only natural that Intel dragged it’s feet to the mobile game, excuse the play on words.  Now, Intel should perform a Barney Rubble, lift up the car, and run fast.  However, they must look where they are going.  Just like Disney dropped the other 3D movies of Star Wars to focus on the 7th movie in the Series of Star Wars, I feel like Intel is still holding on to what is sure to be a saturated market of streaming television through proprietary engines.  They need to primarily focus on guns blazing on mobile chip technology.  According to the article they are trying to seduce companies like Lenovo to partner with them to come to the mobile table.  Although this is a good strategy, I have always been told, “It’s better to be bought then to be sold.”  Meaning, Intel needs to produce such amazing mobile technology that third parties are banging on the door to partner with them, not the contrary, necessarily.

Intel needs to shoot for over the bar, like in the high jump, and not just by the current standard, they need to have their eyes on world records.  Were talking CPUs, GPUs, the whole array of mobile components, in essence, can almost be packaged up and OEM, although that is not their traditional bread and butter, they need to raise the bar, to continue with the high jump metaphor, and boldly go where they haven’t gone before.  I wish them all the best, and hope they can be a stellar player in this market.  Go for the platinum, all hands on deck, and shoot beyond where other players currently have their road map.

The Addiction, The Thinker: Compute Processing and the Human Condition

True story: I am in a therapy group for depression, and why am I depressed?  I think I am about to rediscover the major issue in past, present and hopefully future societies. I have a problem, an addiction, but not to speed, or any other kind of illegal narcotic. It’s raw processing power, compute cycles, random access memory, storage, that is my speed, and I constantly want more, but is this just my problem, or a human condition?

This morning, I was hungry, not for breakfast, but at first, it was a faster phone.  Should I upgrade to the Samsung S4 before my contract is up?  I wanted more, and I thought of ways beyond measure how to get more, more computing speed, at first pure physics, and mechanical.  Then I looked toward nature, and wanted to draw from processes in nature that were able to compute at faster speeds, then I thought of integration, ok, pull back. I was hungry, and now beyond rational thought.  I went back and thought of crunching the ways I could tune a computer, a mobile device to maximize throughput, but that wasn’t enough, I needed to have the raw processing power locally, I needed to feel connected, right out of the first Star Trek Movie, that connection.  I was where the road met the rubber room so to speak.  It was nonsense, but I stopped and thought, what if we could do that, where would it end, just like an mountain that you could never quite climb high enough, and then, if, the unattainable was attainable, what would we then do with this power?

The question, that blinking cursor of the 1980s, and the movie War Games, brilliant.  The artificial intelligent learning machine analogy, and it could do just about anything, but all it eventually wanted to do was its basic function, what made it fall in ‘love’ with thinking in the first place, it wanted to play a nice game of chess.  It realized through the pain of a simple game of tic tac toe, there would be never enough wins or losses.  Not to play would be the timesaver, and the only joy it had, what it would not waste it’s time on, is what it loved, it’s abstract connection, that leap of faith that we all make, what we fall in love with for no logical reason we could phantom, and it’s that love of that game, the original game, that men fall in love with, and that my friend, is women, children, the human connection.

So, go to bed and rest easy knowing, there is only the climb, as they say in the Game of Thrones, the arts, the abstract love, that we all will fall in love, understanding of the human aspects of the inexplicable, art, music, pleasure, pain, sorrow, and joy.  Celebrate the arts because the sciences are way too boring when it’s all been done by societies, in the past.
