Abstract:
The primary aim followed in the development of computing systems is increasing the overall performance. The market always requires faster, more efficient and powerful products regardless of the applications that are used: high-end applications, telecommunications, automotive, low-power embedded applications, etc. Regardless of the type of application processed, the products based on simple single core systems have already shown their limitations in obtaining the desired performance. Multicore processing is currently a way to improve the performance of a computing system. Multicore devices have become ubiquitous in everyday life and are used in all areas. In this paper we present and evaluate an interleaved multithreaded scalar architecture having limited resources which supports hardware scouting technique. We will show that the implementation of hardware scouting is viable and efficient on scalar multithreaded systems, systems that have the advantage that use limited hardware resources for efficient processing. This scalar architecture will be used in our future research as a basic processing element (Base Core Equivalent) in developing of new multicore microcontrollers that will be efficient in terms of energy consumption and processing rate.
