Re: nand2tetris HACK computer
Hi kwx, The design, I've in mind will cover some of the ideas, mentioned in nand2tetris. However I can't beat a whole organisation, but together we will approach the idea. In the presentation you can see the main-components. ALU, Registers, Data-Memory, Program-Memory, Instruction-Pointer, Control-U...

Computer Architecture
To everybody, who’s interested To understand this complex design, I’ve divided the whole circuit into several little circuits. I will upload this circuits from time to time, (hopefully every two or three weeks). You’ll get an explanation within every circuit. Then you can give any comments, suggesti...

Re: Interrupt request
Hi Volvagia, In my opinion, you don't really know the concept of interrupts. Feel free to correct me if I'm wrong. Here you have, in a nut-shell, the stuff you need to know. 1. Interrupts are level-triggered or edge-triggered (The desired possibility is programmable.) 2. Don't control the interrupt-...

Re: Need help with a logic expression and truth table
Hi Shiinobii, I've seen your problem. In the attachment, you'll find the solution for the first problem. I didn't solve the other problems, for that you'll need the same solution. Concerning the second problem, you'll have to do the same. There is also an other expression possible. For the third pro...

1 bit Calculator
L.s., Hi everybody (and especially JekasG), I've seen, that many persons are interested in the logic and arithmetic calculator. At the moment JekasG mentioned the problems with designing such a calculator, I answered right away. But,,,,, I didn't hear anything. So I decided to publish the answer. On...

Re: I want to make a clock that displays time with 15 Led's
Hello Martzz, Your clock is a marvellous idea (as Eugene already mentioned). He advised you to look at his design of a clock. Maybe this design is confusing you a little bit. After reading your message, I understand, that you aren't a electronic engineer, because you mixed the clock (showing the act...

Colored LEDs
Dear Administrator, After reading the problem of Martzz (a very nice idea), I would suggest the next thing. a multi-color LED. As in real life, this LED can have three connections, one for each primary color (RGB). Not connected inputs don't affect the color. A combination of inputs gives a new colo...

Video Graphics Array
L.s., The new feature, "the Graphics Array", is worthful addition to this program. I would have added it with my new Keyboard, but alas, I broke off the connector of my USB-stick. Many new files, including the rest of my library are lost. (making a Back-Up is very wise indeed). If you want...

Re: Arithmetic and Logic Calculator
Dear JekasG, I do understand the problem very well, but I won't give you the answer right away. The whole problem is well described by your teacher. To help you, I will give you an other description. You have to make an 1-bits ALU, (Arithmetic and Logic Unit), four 1-bits input registers, an 1-bits ...

Re: JK Flip-Flop via 12 Gates
Hello LLAD, I've just returned from my vacation in France. Just before I did leave, I read your answer and your challenge (in my opinion) So I took a pen and a lot of paper with me, trying to find your solution. After several days (sitting in the sunlight), I found several solutions, but all off the...
