In this paper a coursc on rcal-time DSP systems design and implementation is prcsented which makes use of the MATLAB and thc Texas Instruments TMS320C621 I DSP Starter Kit (DSK). Thc studcnts attending this coursc get familiarized with the operation of DSP algorithms on an embedded digital signal processor. This coursc cmphasizcs thc issue of the transition from an advanced design and simulation environment, like MATLAB, to a DSP sonware environment, like Code Composer Studio IDE.
Abstract-This paper presents the online conduction of the System Design with DSPs laboratory sessions through the R-DSP Lab (Remote Digital Signal Processor Laboratory). This interactive RL (Remote Laboratory) supports the verification of DSP applications which are written offline by the students in C and/or assembly programming language, through an internet accessible and user friendly control environment. The latest and most important feature of the R-DSP Lab which is also proposed in this paper, is the remote control of student's DSP applications through GUIs (Graphical User Interfaces) developed by them. In order to demonstrate the above feature, the implementation and verification processes of one laboratory session are presented. The assessment and evaluation results of both the System Design with DSPs laboratory sessions and the R-DSP Lab, are also discussed.
SUMMARYA new configurable analogue block (CAB), the key element in the design of field programmable analogue arrays (FPAAs), is introduced in this paper. This CAB is based on wave equivalents of the passive elements and it is easily reconfigurable resulting in very simple and versatile FPAA structures. The proposed topology employs a minimum number of switches in the signal path due to the absence of the interconnection network required in other FPAA structures, and thus an improved performance is achieved in comparison with the already introduced corresponding programmable configurations.
Abstract-The purpose of this paper is to present an approach which could expand the features of Remote Laboratories focused on embedded Digital Signal Processing (DSP) systems. The proposed approach is based on a system which is designed and developed with LabVIEW and is called R-DSP Server. Exploiting this system, users are able to develop their own Graphical User Interfaces (GUIs), named Customized GUIs, for the remote control and validation of real-time DSP applications. These GUIs are tailored to the needs of each DSP application and can be implemented in any programming language. The rapid design of Customized GUIs using LabVIEW for the communication with the R-DSP Server is achieved utilizing an implemented set of functions, called R-DSP LabVIEW Toolkit.
