INTRODUCTION According to the ITRS road map [1] and the continuation of Moore's Law [2], the number of transistors on a chip will continue to increase for at least another decade. In order to benefit from the growing integrated chip, engineers has developed a new technique to manage the increased complexity in large chips, called System-on-a- Chip (SoC). SoC refers to integrating all components of a computer or other electronic systems into a single integrated circuit [3] . Bandwidth is a very critical parameter in the SoC system level design. For a balanced bandwidth design, people need to consider not only the heat dissipation and power consumption but also maximum throughput of the whole system any well- designed SoC system must consider any possible balance-breaking aspect which may lead to system architecture re-design and increased costs [4, 5]. Modern embedded computer systems have grown rapidly due to the increasing capability of processing power while the hardware circuits are still kept in a small size. These systems have become more important in our daily lives especially in mobile communication and operating systems, such as cell phones, game consoles, as well as some larger-scale design of sophisticated products, for example; cars, medical instruments, space shuttle, etc. In order to meet the requirements of shorter response time and faster processing speed, people begin to study how to get more speedup and less energy consumption by analyzing the data of the embedded computer system, thus promote the system performance. People always want to run the applications as fast as possible but modern processors cannot always gain the performance improvement by only increasing the frequency of the CPU. Even with the multi-processor architecture, some sophisticated applications requiring huge data calculation still cannot meet expectations because software applications written in high level LOW POWER MOBILE OPERATING SYSTEMS WITH PROFILING HARDWARE ACCELERATION By ABSTRACT In this paper, a System-on-a-Chip (SoC) based hardware acceleration solution for low power mobile operating systems is proposed. In mobile communication systems, it is very costly to transform the entire software application into a hardware solution. However, some applications may have such a need due to their high performance and low power requirements. These software systems consist of several kind of functions and some of these functions will be invoked at a very high frequency. The speed and energy consumption are two major concerns for modern system development , thus it is important for designers to balance the tradeoff between these two factors. If the system can process very high-speed operations and consume less energy, it is an efficient design. The basic idea of this paper is to only transform those highly used functions into hardware by using the proposed profiling and hardware acceleration methodology. The solution that this paper will demonstrate is to convert the system into a cost effective hardware-software co-design. Experimental
