Easiest Way to Run Multimedia (GUI) Applications Inside Docker

In this post I will show you not only how to run any multimedia application inside docker, but also in efficient and easy way.

Requirements:

• Linux OS and Docker (tested on ubuntu)

• X or Wayland (Linux Display Servers)

  • Ensure that the packages for an X or Wayland server are present on the Docker host. Please consult your distribution's documentation if you're not sure what to install. A display server does not need to be running ahead of time.

• X11docker

  • x11docker allows Docker-based applications to utilize X and/or Wayland on the host. Please follow the x11docker installation instructions and ensure that you have a working setup on the Docker host.

What is X11Docker?

Reference: https://github.com/mviereck/x11docker/

x11docker allows to run graphical applications (or entire desktops) in Docker Linux containers.

• Docker allows to run applications in an isolated container environment. Containers need much less resources than virtual machines for similar tasks.

• Docker does not provide a display server that would allow to run applications with a graphical user interface.

• x11docker fills the gap. It runs an X display server on the host system and provides it to Docker containers.

• Additionally x11docker does some security setup to enhance container isolation and to avoid X security leaks. This allows a sandbox environment that fairly well protects the host system from possibly malicious or buggy software.

Compress Verilog Guide

Hi, in this post i will upload a pdf file which i have written as a guide to verilog programming.

Note that this guide is useful for a person who has some experience with verilog and wants to remember important functions and techniques in verilog in order to write verilog programs for FPGA and other hardwares.
all of contents include examples.

List of contents:

• variables
• concat and replicate
• operators
• module and test bench (with examples)
• port binding
• blocking and non-blocking assignment
• clock generate
• initial and always block (parallel blocks)
• combinational logic design
• reduction operators
• state machines

variables in verilog:

-reg (can have vector identity)

-integer

-real

-time,realtime

 

assignment: beceause they are not wires, they should be assigned only in sequential blocks(always,initial,task,funcion)

read: can be read anywhere (i.e. a driver for a wire)

 

--------------------------------------------------------------------------

variables and wires default is X

--------------------------------------------------------------------------

integer : 32bit int-default is X

real : 64bit floating point-default is 0.0

ONLY used in test bench

--------------------------------------------------------------------------

time variable:

time my_time;

my_time =$time;// get current time of simulation

-------------------------------------------------

vector:

e.g. 

reg [3:0]A = 3'b 1001;

array:

e.g.

reg A[3:0] = 3'b 1001;

------------------------------------------------------------

multi-dementional wire and reg:

e.g. 

reg [7:0] var [1:10][1:100];

reg [7:0] mem [1023:0];

--------------------------------------------------

a value is considered as X if all bits are 0 and X or 0 and Z or 0 and x and z
