Multiply-accumulator (MAC) is the central unit used in digital signal processors (DSP) that are now widely found in many consumer electronic devices. With current emphasis on minimizing operating power and yet maximizing computation performance for DSPs, efficient MAC architecture with low power consumption and high computation performance is hence desired. This paper proposes a low power pipelined...
Embedded systems have been widely used. Therefore, it is important to ensure the safety. Model checking is effective to ensure the safety for systems. We have developed Behavior Extractor to model the behavior of embedded assembly programs automatically. The model is used for model checking. In addition, we have introduced the undefined value to reduce the number of states.
A new cryptographic standard FPGA board SAKURA-G equipped with a 45-nm Xilinx Spartan-6 was developed to evaluate the security of cryptographic circuits against physical attacks and to measure the hardware performance of encryption algorithms. In addition to its rich array of capabilities, improved power analysis functionality over previous standard boards SASEBO-GII and SASEBO-G is demonstrated thorough...
High-speed hardware for Keccak, which was selected as a new standard hash function named SHA-3, was developed and its performance was evaluated against SHA-1 and −2 circuits through the use of various FPGA platforms. The results showed that Keccak is suitable for high-speed hardware implementations, but it is getting harder to implement on new FPGA devices, due to the current trends in architecture...
