With the increasing use of Field-programmable gate arrays (FPGAs) in embedded systems and many embedded applications, failure to protect FPGA-based embedded systems from cloning attacks has brought serious losses to system developers. This paper proposes a novel combinational logic binding technique to specially protect FPGA-based embedded systems from cloning attacks and provides a pay-per-device...
An embedded processor inside an FPGA has a lot of benefits. Application specific peripherals can be chosen based on the requirement. The system can be made more fruitful and powerful by adding peripherals, peripheral controllers, memories, memory controllers and busses. Soft core processor is the HDL model of a processor designed over an FPGA. Nios-II is the second generation of the soft-core processor...
This paper describes embedded Linux system implementation on third generation Wireless Open Access Research Platform (WARP v3). The purpose of this implementation is to integrate operating system (OS) with radio communication system to accomplish flexible and stand-alone communication node for testing different wireless communication protocols. Achieved Linux Enriched WARP v3 (LE-WARP v3) design is...
A significant part of industrial systems have requirements on long life times. Such requirements on the complete system impose requirements on its corresponding embedded systems to be operational for an equally long time. As a consequence it is of paramount importance to be able to replace obsolete components of the embedded systems during the life time of the system, and to be able to update part...
Zero-Degree Detector (ZDD) is a new Detector of Beijing Electron Spectrometer III (BESIII) for both double gamma event detection and luminosity monitoring to substitute the old luminosity monitor. A new luminosity readout is described in this paper which is designed in double width AMC/MTCA form factor with a large Xilinx Virtex5 FPGA in addition to normal electronic signal formation. A FPGA embedded...

The paper also describes...
Nowadays, computers are indispensable tools for most of everyday activities ranging from consumer electronics to industrial process automation. Complexity of new applications leads computer engineers to use embedded systems in order to develop high performance technological solutions that can achieve high speed processing while exploiting hardware resources efficiently. In order to develop embedded...
This survey first introduces index generation functions, which are useful for pattern matching in the communication circuit. Then, it shows various methods to realize index generation functions by using LUTs and memories. These methods are useful to design FPGAs with embedded memories.
One of the major costs and inhibitors to practical robotics research is the time required for the creation of the embedded systems that implement the discrete event control in experimental robot systems. Using a standardized system architecture can reduce this time, but is often not feasible due to the rapidly varying requirements present in robotics research, and the considerable cost associated...
Artificial Neural Networks (ANN) are used to perform tasks like classification, pattern recognition and function approximations in many cases to which traditional approaches are not well suited. Hardware implementations have been presented, mainly in academical works, in order to take advantage of the inherent parallelism in ANNs. In the field of embedded systems it is desirable to have faster and...
Multiple Target Tracking (MTT) algorithms are widely used in various military and civilian applications but its use in automotive safety has little been investigated. In MTT algorithms, implemented in embedded systems, it is important to use the minimum required resources to allow the entire DAS system to be integrated on the same chip (data acquisition, MTT and alarm restitution). This allows the...
An advantage of a RLD (Reconfigurable logic device) such as an FPGA (Field programmable gate array) is that it can be customized after being manufactured. However, there is a problem related to standby power when using it in SoC used in embedded systems. Power gating, which is one of the power reduction techniques, is difficult to use in SRAM-based RLDs because of the high overhead - data hibernation...

We are investigating the utilization of reconfigurable hardware, due to its flexibility and performance, for data mining...
In Embedded Systems, the calculation of RSA cryptographic operations is sometimes hard to achieve if time constraints must be observed. In the following, we present an approach to increase processing power regarding cryptographic operations using FPGA (Field Programmable Gate Array) technology. The FPGA, which is present in many designs anyway, computes parts of the operations, allowing the embedded...
The concept of hardware resource virtualization which was initiated in virtual memory organization has recently expanded towards virtualization of computing resources in partially reconfigurable FPGAs. However, this kind of resource virtualization requires mechanisms for flexible allocation/relocation of components associated with data execution processes. The ability for on-chip component relocation...
In this paper, we design and implement a cryptosystem SoC (CSoC). We combine a virtual microprocessor and AMBA bus to elaborate an embedded system model that is capable of shortening the testing time of the global system and calculating the performance for various types of microprocessors. The virtual microprocessor instead of the physical one is used to control the entire system, so that the high...
With the evolution of programmable structures, that become more heterogeneous, the process of mapping a design into these structures becomes more and more complex. Modern FPGA chips are equipped with embedded memory blocks that can be used to increase the implementation quality of the design.

To ensure security and robustness of the next generation of Physically Unclonable Functions (PUFs), we have developed a new methodology for PUF design. Our approach employs integration of three key principles: (i) inclusion of multiple delay lines for creation of each response bit; (ii) transformations and combination of the challenge bits; and (iii) combination of the outputs from multiple delay...
Microcontrollers are widely used in many handheld devices and embedded systems. Thus, low power, reliability, and robustness have been becoming the critical issues for these microcontrollers. Asynchronous circuits may be one of the best solutions to answer these problems. It is widely known that the 8051 processor is the most popular 8-bit microcontroller; however, because of its CISC nature, the...
