Embedded Software Development

Using specific programming languages (like C and C++) to write code for a specific hardware device in which it runs is called embedded software development. It makes the device smart by performing actions based on user's input which improves the user experience. They are designed to perform function-specific tasks rather than doing multiple tasks like computers. The embedded system is incredibly intuitive. An embedded software system could be a system developed and organized on any device, apart from an old-fashioned computer. It is the brain of a specific device; however, it is a solely useless tool and simple to elucidate what software system is embedded.

An example of a MISD machine is referred to as a systolic array. A set of data processing components that are linked together in the form of a pipeline network or "wavefront" is referred to as a systolic array. Because the execution of each of these components is kicked off by the reception of data, each of these components is self-contained and does not need a program counter. Calculations are performed in "lock-step" by systolic arrays that have clocks that are synchronized, with each CPU executing alternate phases of computation and communication.
