New techniques for superscalar instruction issuing are presented. It is shown that the data dependency check for both in-order and out-of-order issuing can be performed in O(logw) gate delay using O(w2) primitive gates, where w is the size of the instruction buffer. Furthermore, we present a new counting based technique for assigning instructions to resources. It requires a delay of O(logw+logm...

The Cadence Tensilica ConnX DSP family based on the Xtensa® customizable processor is specifically designed for wireless communication modem (PHY layer 1) systems. Cadence has worked closely with customers and software PHY companies that create wireless communication algorithms to drive product development. The Xtensa customizable processor gives modem developers a powerful starting point for s...

Montgomery multiplication normally spends over 90% of its execution time in inner loops executing some kind of multiply-and-add operations. The performance of these critical code sections can be greatly improved by customizing the processor’s instruction set for low-level arithmetic functions. In this paper, we investigate the potential of architectural enhancements for multiple-precision Montg...

Machine Learning (ML) is traditionally formalized as the study of learning concepts from labeled examples. We are interested in providing a way for a human teacher to interact with a learner using natural instructions, thus allowing the teacher to communicate the relevant domain expertise to the learner without necessarily knowing anything about the internal representations used for learning. W...

The application of zone of proximal development (ZPD), as a major tenet of Vygotsky’s sociocultural theory (SCT, 1978), has recently been invited in the L2 learning/teaching profession. This study mainly examined whether Iranian EFL learners’ interactions in diverse ZPD-activated proximal contexts through the use of storytelling instruction could improve their oral (speaking) proficiency and at...

The studies on the merits of processing instruction (PI) and output-based instruction (OI) have mostly treated the two approaches as mutually exclusive. To address the potentials of combining interpretation and production activities, this research compared the two isolated approaches of PI and OI with two combined approaches in which processing and output tasks were used in two opposite orders ...
