One of the main components of any general-purpose machineis the microprocessor, this component can be found at the heart of every machine: from standard servers and high performance computing nodes to portable mobile platforms. Its main task is to correctly execute programs as fast as it can, having the production cost and consumption as border conditions.The research in processor architectures centers in optimizing the processor design according to the specified functionality and having into account present and future technologies. This optimization can be based on different parameters: performance, consumption, production cost, surface.In this work, we propose a novel mechanism combining software andhardware that allows to improve the Instruction Level Parallelism using simple cores and light threads. A modified processor is implemented using a simulation tool and two examples are presented: sorting an array and filtering a matrix. In both cases, promising results are obtained.
