Hardware architecture

<h2 id="background">Background</h2>

Prior to the advent of digital computers, the electronics and other engineering disciplines used the terms system and hardware as they are still commonly used today. However, with the arrival of digital computers on the scene and the development of software engineering as a separate discipline, it was often necessary to distinguish among engineered hardware artifacts, software artifacts, and the combined artifacts.
A <a href="/facts/Computer_program/e38jH9N9">programmable</a> hardware artifact, or machine, that lacks its computer program is impotent; even as a software artifact, or program, is equally impotent unless it can be used to alter the sequential states of a suitable (hardware) machine. However, a hardware machine and its programming can be designed to perform an almost illimitable number of abstract and physical tasks. Within the computer and software engineering disciplines (and, often, other engineering disciplines, such as communications), then, the terms hardware, software, and system came to distinguish between the hardware that runs a <a href="/facts/Computer_program/e38jH9N9">computer program</a>, the software, and the hardware device complete with its program.
A hardware can be controlled from a software with the help of a middle device called hardware controller, this hardware controller can be used to perform various automated task from hardware, generally hardware controller consist of GPIO(general purpose input and output) pins, these pin's behaviour controlled by the piece of code.<a class="footnote-ref" id="fnref:6" href="#fn:6">6</a>
The hardware engineer or architect deals (more or less) exclusively with the hardware device; the software engineer or architect deals (more or less) exclusively with the program; and the systems engineer or <a href="/facts/Systems_architect/SXvEJzNg">systems architect</a> is responsible for seeing that the programming is capable of properly running within the hardware device, and that the system composed of the two entities is capable of properly interacting with its external environment, especially the user, and performing its intended function.
A hardware architecture, then, is an abstract representation of an electronic or an electromechanical device capable of running a fixed or changeable program.<a class="footnote-ref" id="fnref:7" href="#fn:7">7</a><a class="footnote-ref" id="fnref:8" href="#fn:8">8</a>
A hardware architecture generally includes some form of analog, digital, or <a href="/facts/Hybrid_computer/qIEpbyzR">hybrid electronic computer</a>, along with electronic and mechanical sensors and actuators. Hardware design may be viewed as a 'partitioning <a href="/facts/Scheme_(mathematics)/c7uSqGqL">scheme</a>,' or <a href="/facts/Algorithm/fnl5NmRt">algorithm</a>, which considers all of the system's present and foreseeable requirements and arranges the necessary hardware components into a workable set of cleanly bounded <a href="/facts/Subsystem/hmqQ4ASX">subsystems</a> with no more parts than are required. That is, it is a partitioning scheme that is exclusive, inclusive, and <a href="/facts/Collectively_exhaustive_events/DCK4rxvW">exhaustive</a>. A major purpose of the partitioning is to arrange the elements in the hardware subsystems so that there is a minimum of electrical connections and electronic communications needed among them. In both software and hardware, a good subsystem tends to be seen as a meaningful "<a href="/facts/Object_(computer_science)/eX99dtAw">object</a>." Moreover, a clear allocation of user requirements to the architecture (hardware and software) provides an effective basis for <a href="/facts/Verification_and_Validation/hgqysrzb">validation tests</a> of the user's requirements in the as-built system.
