DSCBlocks is an open-source platform in hardware and software developed in JavaFX, which is focused on learning embedded systems through Digital Signal Controllers (DSCs). These devices are employed in industrial and educational sectors due to their robustness, number of peripherals, processing speed, scalability and versatility. The platform uses graphical blocks designed in Google’s tool Blockly that can be used to build different Algorithm Visualizations (AVs). Afterwards, the algorithms are converted in real-time to C language, according to the specifications of the compiler for the DSCs (XC16) and they can be downloaded in one of the two models of development board for the dsPIC 33FJ128GP804 and dsPIC 33FJ128MC802. The main aim of the platform is to provide a flexible environment, drawing on the educational advantages of the AVs with different aspects concerning the embedded systems, such as declaration of variables and functions, configuration of ports and peripherals, handling of Real-Time Operating System (RTOS), interrupts, among others, that are employed in several fields such as robotics, control, instrumentation, etc. In addition, some experiments that were designed in the platform are presented in the manuscript. The educational methodology and the assessment provided by the students (n = 30) suggest that the platform is suitable and reliable to learn concepts relating to embedded systems.

Abstract— Literally embedded systems are defined as equipment that computes a particular job. Embedded Linux System was also developed as a means of education, one of which is ED-255EK Embedded Education Platform, designed to be very practical and consume very low power. ED-255EK is also equipped with a PXA255 processor that is compatible with ARM version 5TE ISA, so it can be used to carry out various kinds of lab work or experiments on embedded systems. The working principle of this tool begins with the configuration of data communication between Fedora Linux and ED-255EK. When the communication goes well, it is downloaded by the ED-255EK system to a laptop or computer that has been installed with the Fedora 9.0 Linux operating system. To take advantage of the ED-255FPGA module, driver module installation is required first, after which the application program is installed. Laptops or computers that have installed the Fedora 9.0 Linux operating system will act as input and output programs making it easier to monitor each module that is being run. The module used is the ARM 1923 Robot Module and Voice Module ED4321.

Automotive infotainment applications are examples of embedded systems in which a heterogeneous software stack is used, which most likely comprises a real-time operating system, an automotive-grade Linux, and possibly Android. Thanks to the availability of modern systems-on-a-chip providing multicore computing platforms, architects have the possibility of integrating the entire software stack in a single chip. Embedded virtualization appears an interesting technology to achieve this goal, while providing the different operating systems the capability of exchanging data as well as optimizing resource usage. Although very well known in server-class systems, virtualization is rather new to the embedded domain; in order to leverage its benefits, it is therefore mandatory to understand its peculiarities and shortcomings. In this chapter, the authors illustrate the virtualization technologies with particular emphasis on hypervisors and Linux Containers. Moreover, they illustrate how those technologies can cooperate to fulfill the requirements on automotive infotainment applications. Finally, the authors report some experimental evidence of the performance overheads introduced when using embedded virtualization.

Multiprocessor Embedded Systems

In many safety-critical missions, more and more Multiprocessor Embedded Systems are used to provide the ability of fault tolerance. Using Operating System can easy software design and make software development more efficient. Because of the limited resource in Embedded Systems, many advanced technologies used in common desktop multiprocessor environment have not been used in Embedded RTOS yet. In this paper, we introduce the technologies of Virtual CPU Pool and Multiprocessor Processor Communication Interface to solve task distributing and communication between deferent CPUs. After using and mending uC/OS, I finally realize and test an Operating System in a kind of SMP multiprocessor hardware module successfully.
