The widespread use of embedded systems mandates the development of industrial software design methods, i.e. computer-aided design and engineering of embedded applications using formal models (frameworks) and standardized prefabricated COMPONENTs, much in the same way as in other mature areas of engineering such as mechanical engineering and electronics. These guidelines have been used to develop COMPONENT-based Design of Software for Embedded Systems (COMDES). The paper gives an overview of the COMDES framework, followed by a presentation of a generic COMPONENT types, such as function blocks, activities and function units. The execution of function units is discussed in the context of a newly developed execution model, i.e. timed-multitasking, which has been extended to distributed embedded systems.
16點FFT VHDL源程序，The xFFT16 fast Fourier transform (FFT) Core computes a 16-point complex FFT. The input data
is a vector of 16 complex values represented as 16-bit 2’s complement numbers – 16-bits for
each of the real and imaginary COMPONENT of a datum.

Many CAD users dismiss schematic capture as a necessary evil in the process of creating
PCB layout but we have always disputed this point of view. With PCB layout now offering
automation of both COMPONENT placement and track routing, getting the design into the
computer can often be the most time consuming element of the exercise. And if you use
circuit simulation to develop your ideas, you are going to spend even more time working on
the schematic.
