Nita julian, lazarescu vasile, constantinescu rodica hardwaresoftware codesign method these models take into consideration only the software component and imply the existence of some software lower levels and a hardware platform which can implement the respective model. The following are the major definitions which capture the essence of the area.

The last part of many modern hardware products is the software, a program that allows your hardware to send and receive data over a connection while displaying it to you in a usable way. Software is a program that enables a computer to perform a specific task, as opposed to the physical components of the system hardware. Hardwaresoftware codesign tec computer engineering group.
