Abstract

Increasing the processor resources usability and boosting processor compatibility and capability to support multi-executions models in a single core are highly needed nowadays to benefit from the recent developments in electronics technology. This work introduces the concept of a dynamic switching mechanism (DSM), which supports multi-instruction set execution models in a single and simple processor core. This is achieved dynamically by execution mode–switching scheme and a sources–results locations computing unit for a novel queue execution model and a well-known stack based execution model. The queue execution model is based on queue computation that uses queue-registers, a circular queue data structure, for operands and results manipulations and assigns queue words according to a single assignment rule. We present the DSM mechanism and we describe its hardware complexity and preliminary evaluation results. We also describe the DSM target architecture.
