The key to success in today’s embedded market is the ability to respond quickly to fluctuations in market demand, last-minute design changes and competitive challenges. Microcontrollers (MCUs) have provided versatile, configurable platforms for embedded systems for many years in this respect, giving developers the flexibility to implement new system features easily and efficiently through firmw...

AbstractIn this work faster unsigned multiplication has been achieved by using a combination of High Performance Multiplication [HPM] column reduction technique and implementing a N-bit multiplier using 4 N/2-bit multipliers (recursive multiplication) and acceleration of the final addition using a hybrid adder. Low power has been achieved by using clock gating technique. Based on the proposed t...

This paper describes an investigation of potential advantages and risks of applying an aggressive asynchronous design methodology to Intel Architecture. RAPPID (“Revolving Asynchronous Pentium® Processor Instruction Decoder”), a prototype IA32 instruction length decoding and steering unit, was implemented using self-timed techniques. RAPPID chip was fabricated on a 0.25μ CMOS process and tested...

Optimization is essential in many scientific and economical areas, but it is often too complex to be tackled by simple straightforward calculations or by trial and error. Two well-known methods to find low-lying minima in such complex systems are simulated annealing and the genetic algorithm. In these methods artificial fluctuations control the probability of the system to overcome a local mini...

A polynomial-based division algorithm and a corresponding hardware structure are proposed. The proposed algorithm is shown to be competitive to other conventional algorithms like the Newton-Raphson algorithm for up to about 32 bits accuracy. For example, using Newton-Raphson with less than 12 bits accuracy of the initial approximation, requires 33% more general multiplications than the proposed...

The 6 = 3 × 2 huge Lie algebra Ξ of all local and non local differential operators on a circle is applied to the standard Adler-Kostant-Symes (AKS) R-bracket sckeme. It is shown in particular that there exist three additional Lie structures, associated to three graded modified classical YangBaxter(GMCYB) equations. As we know from the standard case, these structures can be used to classify in a...
