Abstract :
Limits of instruction level parallelism and the higher transistor density sustain the increasing need for multiprocessor systems: they are rapidly taking over both general purpose and embedded processor domains. Nowadays, since these processors must handle a wide range of different application classes, there is no consensus over which are the best hardware solutions to exploit the best of ILP and TLP together. Current multiprocessing systems are composed either of many homogeneous and simple cores, or of complex superscalar SMT processing elements. In this work, we have expanded a reconfigurable architecture to be used in a multiprocessing scenario, showing the need for an adaptable ILP exploitation even in TLP architectures. We have successfully coupled a dynamic reconfigurable system to a SPARC-based multiprocessor, and obtained performance gains of up to 40% even for applications that show a great level of parallelism at thread level, demonstrating the need for an adaptable ILP exploration.
