Abstract

This paper studies the loosely integration of application accelerators consisting of an array of tightly-coupled lightweight reconfigurable processors into a system-on-a-chip. In order to explore a multitude of design variations a C++ simulation model of the accelerator has been integrated with a system-on-a-chip environment consisting of a general purpose processor, a DMA controller, an interrupt controller and a memory module. Dependent on the applications, different kinds of I/O buffers are designed around the processor array and the effects of the buffer size on the overall execution time are evaluated. The evaluations are based on new mathematical estimation models derived from the system and application constraints. The estimations are validated with experimental results with an error less than 1%. Exploring several designs points that using our architecture along with suitable buffer sizes, can improve the system execution time, one to two magnitudes for the selected algorithms. © 2009 IEEE.
