Question 1

Given this addition, $9999_{16} + 1111_{16} = AAAA_{16}$, I'm supposed to interpret the operands and the result as signed integers in two's complement. How can I tell if the result is correct, and ...

Question 2

I'm interested to figure out the main components of a CPU based on a high-resolution image. For example, the Pentium 2 Dixon (reproduced below) clearly has an L2 cache on the right, but I'm not sure ...

Question 3

I'm trying to propose truth tables for the following two rules which are originally defined on page 5 in this paper: Title: An abstract framework for argumentation with structured arguments Author: ...

Question 4

I would precisely like to know if the conjecture BPP=P implies the following: Is it possible to build a classical Boolean circuit whose outputs are statistically indistinguishable from a fair coin ...

Question 5

Recently, when I self-learnt Discrete Mathematics and Its Applications 8th by Kenneth Rosen, it says in 12.4 Minimization of Circuits which uses the Karnaugh Map or the Quine-McCluskey method: ...

Question 6

To borrow part of a description from a similar but distinct question: there exist 2^(2^N) different functions which accept N binary inputs and return a 1 bit output. For the purposes of my question I ...

Question 7

I'm embarking on a long-term project, aiming to build a computer based on the Intel 8088 architecture. This venture provides an excellent opportunity to deepen my understanding of computer hardware ...

Question 8

I'm a student trying to learn more about CMOS design, I already understand assembly and computer architecture, but VLSI is very interesting and I was wondering if you guys knew some good books/games ...

Question 9

So I was reading the use complement operation in the digital logic and found, it is used to give additive inverse of the number and subtracting a number (like we do) is difficult for computer. So it ...

Question 10

I wondered if, for a fixed integer $k ≥ 3$, how can I construct a circuit for each $n \in \mathbb{N}$, that takes as input an n-bit integer $x$ and outputs whether 3 divides $k$? Considering an n-bit ...

Question 11

I'm interested in what the best way is to design a circuit that takes multiple values as input, and then outputs which value is the lowest. If multiple values are the lowest, it outputs "true&...

Question 12

Working on logic design in class, and I'm trying to figure out how to write a specific logic function [and by write, I mean something along the lines of (x NOR y) OR (a NOR b), for example] It asks to ...

Question 13

In the "First Draft" JvN described an adder circuit to do binary addition, which was a much faster way of doing computer addition than using decimal lookup tables as the ENIAC had done. JvN'...

Question 14

While i was going thru my course in Computer System Architecture (book taken Morris Mano) , I saw a question on KMaps can be solved in either of the ways but couldn't get which one to use when :- I’m ...

Question 15

I wonder if there's Digital Logic Circuit (using combinatorial logic gates) that check if number is prime or not. For example given input fixed 8-bit that will produce 1-bit output. 00000101 will ...
