Like the ABCs babies play with before they are old enough for Reddit.)Ĭontent just feels so abstract and foreign (Also in 4th year EE, they may teach you how transistors are made of melted sand. It's like a civil engineer can't build skyscrapers until he understands how gravel, sand and lime make concrete. Flip-flops, counters, timers, synthesizers, memory, processors, probably the screen you're reading this on. Everything else digital is built out of logic gates. Seems really trivial until you start building a million units a month.Īnd those are simple things. Or maybe you save your company $50,000 a month by eliminating some unnecessary ICs that may only a cost few extra pennies per unit. These seem like gimmicks, until you you don't have enough board space for a bigger processor or dedicated chip.

I once sent FSK modulation with a PIC serial port and timer tied to a quad NAND gate. You can digitally modulate a spread spectrum radio baseband with an XOR gate( and admittedly a lot of filtering afterwards). Your can make an inverter of of one transistor. Knowing a few digital logic tricks can make the difference between a project that works, and one that doesn't.Ī couple tidbits I remember from my early days. How does our hero save some processor cycles toship the new feature upgrades that pay his salary/bonus? You already shipped a kazillion units with a 10 year old processor.

No one is gonna want to upgrade the processors. But one day, you'll be working on some system that isn't quite fast enough. If you are just gonna write DSP in high level languages, yeah, you might never care about those assembly language details. You have to understand the basics, to build up to the cutting edge stuff.ĭo you need it for DSP? Maybe not for simple stuff you run on a PC, but most(if not all?) processors have instructions that do AND, OR and XOR. Or maybe when you were in grade school and times-tables seemed stupid when there were calculators everywhere.ĭigital logic is kinda like that. Think of it like this: remember when you were in algebra in high school, and wondering who the hell cares what x is? When am I ever gonna use this? What is it related to in the real world? Then you get to physics, and find out you can aim artillery 20miles away with algebra. A few years later I was on a team making a microprocessor from scratch, like from logic gates, and then later, professionally, doing FPGA development for my day job. I hated digital logic when I was growing up, and also in undergrad.
