Advanced Encryption Standard is used to cipher data with the motive of secure transmission over a communication channel. In this paper some architectures for AES-128 implementation have been discussed. The basic AES core has been developed for encryption and decryption using Look-up Table and Composite Field Arithmetic. It describes the basic structure of AES in Electronic Codebook mode working on...
Integrated circuit technology has made progress by leaps and bounds in general, but in the space environment radiation of ionized particles still remains as an Achilles' heel for errorless working of integrated circuits. With the continuously shrinking feature sizes, combinational logic (CL) is becoming more susceptible to soft errors. This work involves a simulation study for some of the different...
Embedded processors with cache memories are used to improve the overall performance of the system. To maintain a trade-off between cache size costs vs. performance, it is required to avoid oversize cache. A quick estimation of cache size at the early stage of design cycle may help the system architect to plan the available chip area among processing core, cache memory, register file and other system...
High Speed Computing is a promising technology that meets ever increasing real-time computational demands through leveraging of flexibility and parallelism. This paper introduces a reconfigurable fabric named Reconfigurable High Speed Computing System (RHSCS) and offers high degree of flexibility and parallelism. RHSCS contains Field Programmable Gate Array (FPGA) as a Processing Element (PE). Thus,...
It is observed that due to the availability of fast and highly efficient processors, many embedded system developers are attracted to implement the majority of the system components in software rather than hardware. Software implementation offers a great level of flexibility and scalability of the design. At the same time, a wide choice exists between generic processors, DSP processors, network processors,...
Remote controlling of devices or peripherals interfaced with an MCU is essential in couple of applications in Embedded Systems. Web Server is one of the best solutions to do such task if internet is available at such remote locations. The important aspect of this paper is to port an open source Embedded Linux operating system on the FPGA to manage the hardware resources. It is pre-emptible and can...
