As mobile embedded systems become more prevalent, there is an increasing demand to make processor pipelines more power efficient. Conventional pipeline inefficiencies include unnecessary accesses to the register file due to duplication or avoidable computation from constantly checking for forwarding and hazards at points where they cannot possibly occur, repeated calculation of invariant values, etc. It is desirable to develop an alternative processor design that can avoid these wasteful energy consumption aspects of a traditionally pipelined processor while still achieving comparable performance.A statically pipelined processor is expected to achieve these goals by having the control during each cycle for each portion of the processor explicitly represented in each instruction. The pipelining is in effect statically determined by the compiler, which has several potential benefits, such as reducing energy consumption without degrading performance, supporting a less complex design with a lower production cost, and being able to apply more effective compiler optimizations due to instructions having more explicit control of the processor.If successful, the broader impact of this research is manifold. The use of ultra-low power embedded devices, such as bio-implantable microelectronic devices, can significantly affect everyday activities. A new generation of ultra-low power processors will enable these devices to be more feasible to develop and deploy. Educational efforts to introduce the latest architecture and compiler enhancements in the classroom complement our research. Steps will also be taken to increase female and minority enrollment at both institutions in their Computer Science and Computer Engineering programs.

随着移动嵌入式系统变得越来越普遍，使处理器管道更加有效的需求越来越大。 传统的管道效率低下包括由于重复或不断检查无法发生的转发和危害的可避免的计算而不必要的访问，重复计算不变的值等等。值得避免在这些传统的流动过程中，可以避免在这些浪费的能源消耗方面达到这些浪费的能量，而在这些方面可以实现这些浪费的过程。在每个说明中明确表示处理器的每个部分中的每个周期内的控制。 该管道实际上是由编译器静态确定的，该编译器具有多种潜在的好处，例如在不降低性能的情况下降低能源消耗，支持较低的生产成本的不太复杂的设计，并能够通过对处理器进行更明确的控制，因此能够采用更有效的编译器优化。使用超低功率嵌入式设备（例如可植入生物植入的微电器设备）可能会显着影响日常活动。 新一代的超低电源处理器将使这些设备能够更可行地开发和部署。 在课堂上介绍最新的建筑和编译器增强功能的教育努力补充了我们的研究。 还将采取措施，以增加计算机科学和计算机工程计划中的两个机构的女性和少数群体入学率。
