Development of a remote lab with micro-processor & DSP with FPGA accelerator

TL;DR: The setting up of a DSP Cloud Lab, a setup to execute programs remotely, and the design choices made at different stages and the extent to which it facilitates or restricts the use of the DSP boards for a developer are discussed.
Abstract: This paper describes and discusses the setting up of a DSP Cloud Lab, a setup to execute programs remotely. The programs can be executed on a variety of DSP boards; they could be microprocessor assembly language programs or programs written in assembly language requiring powerful DSP boards or even DSP boards with an FPGA accelerator. The boards used are based on Blackfin Architecture. For a student / developer who writes codes and tests on it, it appears as if they have exclusive use of the boards. However, the boards are highly shared, enabling a large number of students / developers to use them simultaneously. This paper also discusses the design choices made at different stages and the extent to which it facilitates or restricts the use of the DSP boards for a developer.

TL;DR: In this paper, a sample of 98 undergraduate students from a degree course in Energy Engineering was used for this study; 57 of these students ran experiments in a laboratory of electrical machines and 41 in a photovoltaic systems laboratory.
Abstract: Remote lab experiences are proliferating in higher education, although there are still few studies that manage to build a theoretical framework for educational assessment and design of this technology. In order to explore to what extent the use of facilitators of proximity to the laboratory and the autonomy of the experiment makes remote laboratories a technology accepted by students, two remote labs different yet similar educational conditions in laboratories are used. A sample of 98 undergraduate students from a degree course in Energy Engineering was used for this study; 57 of these students ran experiments in a laboratory of electrical machines and 41 in a photovoltaic systems laboratory. The data suggest using conditions that facilitate the proximity of the laboratory and the autonomy in the realisation of the experiment; in both laboratories the experience was positively valued by the students. Also, data suggest that the types of laboratory and experiment have influences on usability – auto...

TL;DR: In this paper, a method and an apparatus for designing a cloud-based radio access network, C-RAN, is provided, which comprises dividing the access network into two or more tiers having different processing capabilities, and determining the physical location of the tier, BBU, having most efficient processing capability for serving the remote radio heads on the basis of the information about the location and required quality of service of at least part of the one or more radio heads.
Abstract: A method and an apparatus for designing a cloud based radio access network, C-RAN, are provided. The solution comprises dividing (302) the access network into two or more tiers having different processing capabilities; receiving as an input information about the physical location of one or more remote radio heads, RRH, of the network and required quality of service of the remote radio heads; and determining (306) the physical location of the tier, BBU, having most efficient processing capability for serving the remote radio heads on the basis of the information about the location and required quality of service of at least part of the one or more remote radio heads.

TL;DR: The design, implementation and evaluation in setting up a remote laboratory for programming microcontrollers on an embedded web server residing over an ARM (Advanced RISC Machine) microprocessor based embedded system is proposed in this paper.
Abstract: The design, implementation and evaluation in setting up a remote laboratory for programming microcontrollers on an embedded web server residing over an ARM (Advanced RISC Machine) microprocessor based embedded system is proposed in this paper. The hex files or c codes generated with the help of various client machine IDE's (Integrated Development Environment) can be transferred to the server through the TCP (Transmission Control Protocol) port 80 which in turn programs the microcontroller attached to beaglebone with help of various software tools like avrdude, mspware etc. The system is designed by setting up an Apache web-server over the Beaglebone Black single board computer. Client machines can access the server through the static IP address assigned. The evaluation of the remote lab is done by programming Atmel AT89s52 microcontroller remotely and by performing a webcam interface to beaglebone thereby achieving video streaming, the real time video result can be viewed at the client end.

TL;DR: The motivation, hardware setup, software setup and remote user access for using the laboratry are delineated and the performance, scope and scalability are discussed with emperical data.
Abstract: As the current world moves towards e-learning, this paper discusses about a recently developed remote Digital Signal Processing lab at IIT Madras. This lab enables the students to use Blackfin 537 based DSP kits to perform their real-time experiments / projects over the Internet. The DSP boards are custom made, with uClinux ported onto them, to facilitate a multi-user environment. This paper delineates the motivation, hardware setup, software setup and remote user access for using the laboratry. Finally the performance, scope and scalability are discussed with emperical data.
