Title
A Novel Composite Method to Accelerate Control Flow on Reconfigurable Architecture (Abstract Only)
Abstract
Reconfigurable Architecture provides a promising solution for embedded systems for high performance, low power and flexibility. Control dependence and control divergence are critical problems that impact the performance. Many methods were proposed to handle control flows efficiently, such as predicated execution and speculative execution. However, they exhibit different performances for different types of control flows, so composite methods are required to provide overall optimal performance. In this paper, a novel architecture is proposed which combines Triggered Instruction and parallel condition. It is designed on the basis of triggered instruction architecture (TIA) while each PE incorporates multiple arithmetic logic units with fast mutual control as in the technique of parallel condition. It can remove branch instructions as well as parallelize control and compute instructions without reconciliation operation, so it explores parallelism in branch level while avoids over-serialization execution in program-counter-based PE. The experiment was conducted on a model in C language and the result shows that the proposed architecture can achieve 80.0% higher performance on average than TIA.
