Abstract

Application-specific instruction set processors assures good tradeoff between efficiency and flexibility in SOC design. However, it is difficult to obtain the extended instructions by manual designs for large programs with various design constraints. A two-phase design flow is proposed to automatically generate application specific instructions to achieve the better performance. Firstly, we translate various applications from C programs to a control/data flow graph. Secondly, a set of proposed algorithms is utilized to analyze the dependency of instructions in the data flow graph as well as to generate and evaluate application-specific instructions. Experimental results indicate that the MiBench applications can be improved about 1.5 to 3.18 times speedup using our generated application-specific instructions.

SOC处理器专用指令生成

特定于应用程序的指令集处理器确保了SOC设计中效率和灵活性之间的良好权衡。然而，对于具有各种设计约束的大型程序，通过人工设计获得扩展指令是困难的。提出了一种两阶段的设计流程来自动生成特定于应用的指令，以达到更好的性能。首先，我们将各种应用程序从C程序转换为控制/数据流图。其次，提出了一套算法来分析数据流图中指令的依赖关系，并生成和评估特定应用指令。实验结果表明，使用我们生成的特定于应用程序的指令，MiBench应用程序的速度可以提高1.5到3.18倍。
