vhdl code for ascending order of numbers

Prime numbers are important for several applications, such as cryptography and information technology. They are also useful for some simpler tasks in mathematics (for example, finding the common factors of two numbers). Prime numbers are usefull in encryption because code breaking computers employ search algorithms that keep multiplying numbers together In order to find a combination to break the code, but if you have a very large prome, the code breaker probably won't find it. The Unique-Prime-Factorization Theorem is so useful, that it is also called the Fundamental Theorem of Arithmetic.
A bar code consists of lines, or bars, if you will, that contain numbers and code for a product. It hold the information for the pricing, the inventory and the SKU numbers or catalog numbers of a certain product. It is also integrated in stores computer system.

Bar code stores numbers only,but QR code can be store be with any multimedia.

VHDL code for 8253 need to be written in structural modeling of VHDL. It will be a bunch of programs related to each and every component or functionality we use in 8253 and need to be combined. It is not a single program. It is a combination of several programs.
VHDL code for home security need to be written in structural modeling of VHDL. It will be a bunch of programs related to each and every home appliance we use and need to be combined. It is not a single program. It is a combination of several programs.
VHDL is a hardware description language. The purpose of any HDL is to represent hardware as a program. We can write a program (code) for any digital circuit using VHDL. With the help of this code, the output of the circuit can be observed before actually designing it physically.

After writing the VHDL code, we wish to verify the code and its functionality. Verifying the code for syntax errors is called compilation. Later, applying the inputs and obtaining the outputs is called simulation. If we are not getting the desired output, we may check our code and re-compile and simulate.

A Test Bench in VHDL is code written in VHDL that provides stimulus for individual modules (also written in VHDL). Individual modules are instantiated by a single line of code showing the port connections to the module. The correctness of the written program can be checked by writing the test bench. It is a collection of VHDL procedures and functions which allow the user to create their own scripting instructions for test stimulus. Designers manually design their test bench inputs to checks the output. The stimulus script or test case contains the instructions in a regular ASCII text file. The test bench VHDL package contains procedures to create instructions, read, parse and execute the test script.
In the synthesis part of a VHDL code, the EDA tool provides technology schematic. It describes the structure and sub-structures of the design. We can watch our design from the system level to the gate level.
In the "architecture" of VHDL, after "begin" statement, if you want, you can apply the inputs. For example, a<='0'; b<='1'; etc. But, if you want the inputs to change periodically, then you should at least apply one "enable" or "clock" pulse.
