SADF Overview
SADF Overview

SADF envelopes and organizes the development process for DSP applications. SADF focuse to process stream data in teal-time. DSP Applicatoin receives stream data at the input, process them, and then provide stream data to the output. Processing could be controlled or modifyed by the control part of the application. Main advantages of SADF are as follows:

SADF consists of three main components that’s organize DSP application development process: SADF Studio, SADF Engine and SADF Engine Libraries.

DSP part responsible to ptocess stream data, and control part are responsible to control processing. For example user interface is a part of the control application.
SADF focuse to implementatin of complete DSP part of application, emulation of Control application and provides interfaces to the user to connect his control application to the DSP part.
Structures of SADF as a component diagram are presented on picture below:
SADF Studio it is grafical development tool that visualizes DSP application and represent DSP part of application in graphical view (like Simulink). SADF Engine it is a component that’s executed on target platform and responsible to manage the DSP part of application. Block Librarys, it is set of standard DSP blocks like Filters, transforms, arithmetic ertc, operations that could be used inside of DSP algorithms.
Also, SADF has two main interfaces: block interface and control interface.
Block Interface used to extend functionality by adding new processing blocks to the engine.
Control Interface used to connect DSP part and control part of application.
