Problem with two's complement fixed point arithmetic in hardware
I am trying to implement a basic spiking neural network on FPGA, and have came across a problem. The design uses fixed point binary addition and subtraction to sum input values. As weights can be ...

I need to capture and store short bursts of synchronous binary bit-stream, arriving at 1.5meg bits/sec [closed]
The binary bit stream arrives on one pin on a circuit board and a synchronous clock arrives on another pin. I don't need to store the clock - it's just there in case I need to use it during the ...

Combinational Circuit: How can 2.5 and 3.5 be represented in a 3-bit truth table?
Design of a combinational circuit with 3 inputs, x, y, z, and 3 outputs, A, B, C. When binary input is 0, 1, 2, or 3, the binary output is twice the input. When binary input is 4, 5, 6, or 7, binary ...

Reduce component count for BCD input error detection
I made this circuit that reads the input of the DIP switches and detects if the input is an error or not a BCD value. The problem is I have 4 inputs for my circuit.
The LED indicate if the input is ...

Adding four numbers of 1 bit each and then cascading them
When I add four bits (NOT FOUR BIT ADDER, only four bits), the result can go to a maximum of 100 (4 in decimal, if all are ones). Now, here 0 (LSB) is the sum and 10 is carry. If I want to transfer ...

Comparison of two numbers of different length
I want to design a circuit at block level using IC 7485 to compare one 6 bit number with another 5 bit number.
My approach is:
Put the most significant bits into the four 7485 comparator inputs. The ...

How to create a BCD to binary encoder that supports multi digit numbers using only logic gates [duplicate]
I've been thinking so long about how can I make a BCD to binary encoder that can encode BCD numbers like for example 11 or even 32767 into binary form (11 ---> 1011) but using only logic gates.
I ...

Struggling with the design for a simple logic circuit [closed]
I'm working on a circuit that would store 4 bits and flash them on an LED. These would be stored on a 4 bit register, and should be outputted when a button is pressed. My goals is to take my 4 outputs ...

I distinctly remember 0 being the sign for on, or a closed circuit. Does anyone else recall learning it backwards? [closed]
Is it just my false memory or does anyone else remember learning that. The 1 if line represented open circuit for off. I was floored to find out it’s the opposite now. So just like the bearstained ...

Determining the best CRC polynomial generator regardless the input data [closed]
I'm given a couple of 16-bit CRC generator polynomial:
\begin{align}
g(p) &= p^{16} + p^{12} + p^5 + 1 \\
g'(p) &= p^{16} + p^{10} + p^8 + p^7 + p^3 + 1
\end{align}
And, without knowing the ...

Confused about bits and bytes: How can 10 bits represent 1024 bytes?
If we have 10 bits, then we can access 2^10 = 1024 different addresses with it, but we say that with 10 bits, we can show 1 kilobytes which is 1024 bytes. I can't understand this. Isn't 1 byte equal ...

How many bits are required for a quotient in binary division?
I saw somewhere that if we have A (dividend) which is 2n-bits and B (divisor) which is n-bit, we can store the quotient in n-bits with a specific condition: the (n-1)th bit of the divisor has to be 1.

How to construct an integer based on the binary input of 8 to 32 GPIO pins
I'm researching a sensor for a project that has multiple methods of returning a value, one of them being a parallel output system that breaks down the value into 16 bit binary and transmits each bit ...
