This paper presents a rounding method for functional iteration algorithms. The new method is made up of a new rounding algorithm and the calculation of a remainder estimation. The rounding method uses the result directly obtained from the algorithm without any transformation. The remainder estimation is calculated in parallel with the algorithm execution. This allow us to avoid the conventional remainder...
Modern handheld embedded systems operate under stringent power and real-time constraints. These systems run highly data-dominated applications from multimedia and wireless domains. Most of these applications spend significant amount of execution time in nested-loops. In order to reduce the loop control overhead several loop controller architectures have been proposed in the past. In this paper we...
Multi-terminal binary decision diagrams (MTBDDs) are useful representation of multiple output Boolean functions. However, construction of such a diagram is a difficult task, especially when in some sense optimum diagram is sought. The paper presents an improved algorithm of MTBDD synthesis aiming at minimum MTBDD width or cost. The presented algorithm is a core of the upgraded version of a synthesis...
Many reversible circuit synthesis procedures have been proposed. A common feature of most methods is that the initial specification must be a completely-specified reversible function. However, often the desired functionality is a, possibly incompletely-specified, irreversible function. In this paper, we consider how to fully automate the process of synthesizing a reversible function given an irreversible...
This paper shows a method to reduce the number of input variables to represent incompletely specified index generation functions. A compound variable is generated by EXORing the original input variables. By using both original and compound variables, incompletely specified index generation functions can be represented by fewer variables. As a means to select variables, a heuristic method using information...
We investigate a form of logic decomposition that generates a 2SPP-P-circuit, which includes two blocks representing the projected subfunctions obtained by Shannon cofactoring with respect to a chosen variable, and a block representing the intersection of the projections. The three blocks are implemented as minimal 2-SPP forms (XOR-ANDOR with XOR restricted to two inputs). The minimization is performed...
