I prefer to measure the duration of the pulse through a pc because the sound of the buzzer will be recorded with a camera so i will analyze the sound signal on my pc.Is this feasible?I think that i can do this with a bandpass filter which will detect the frequency range of the buzzer.Am i...
Hello!I am currently doing a project for the university in which i have to detect a very fast flash(from a camera).So i did a circuit like this https://www.youtube.com/watch?v=LQImmpcFDBw. This circuit make a sound (using a device like this https://en.wikipedia.org/wiki/Buzzer) every time it...
Ok i will try to explain you what i have done in order you to understand and see if i can do something in my case.I want to insert an 16x16 image.The values of the image are the same type(integer) so i decide to insert it as an 16x16 array.The way i follow to do this is to declare 16 one...
I am happy to hear that this will work from the point of the way of thinking.Maybe there are some syntactic errors.I just was wondering if there is a better way to do what i described in the previous post.Thank you very much
Another thing that i want to ask is how to do this :
Imagine a 20x20 array with integer values from 0 to 255.
I want to separate this array in 25 arrays each of one 4x4 and compute the sum of each one of these arrays.So i think that the best way to implement this, is to insert one array(4x4)...
I wrote this code.What i need to do is to insert 4 values at each clock which i store on a 2-dimensional array and i want to compute the sum of these values.
LIBRARY IEEE;
USE IEEE.STD_LOGIC_1164.ALL;
USE IEEE.STD_LOGIC_ARITH.ALL;
ENTITY test IS
PORT( x1 : IN INTEGER RANGE 0 TO 255...
Here is what i want to do.I have 3 inputs each of one has a weight(random).I want to compute the : input1*weight1+input2*weight2+input3*weight3 and if this is greater than a threshold(predetermined) its ok.But if it is less than the threshold i want to fix the weights in order for the...
I am trying to implement a simple neuron in vhdl.I wrote code that works but the question is how to implement the back propagation algorithm in vhdl.What i mean is how to update the weights(values) until the error reaches some desirable value.I need something like GOTO statement if there is...
Question about an array
I would like to insert an 10x10 array in vhdl.Each element of this array would be a bit vector of 8 bits.So i declare a new type of an 10x10 array and a signal to refer to this array.The problem is that if i declare an input of this type of array the system will use too...
I want to insert an image as an array in VHDL.I am new to the language so i the simplest thing i thought was this :
PACKAGE newtype IS
TYPE vector_array IS ARRAY (0 to 9,0 to 9) OF
BIT_VECTOR(7 DOWNTO 0);
END newtype;
USE WORK.newtype.ALL;
ENTITY test IS
PORT ( inp1 : IN vector_array);
END...
