Multi-dimensional logarithmic number system; low power 2D hardware text and image acceleration for ubiquitous mobile devices

随着无处不在的移动设备在当今社会越来越普及，以及高速数据网络（如4G）和更高清晰度显示屏的引入，为了最大限度地延长电池寿命，需要对常见的底层功能进行优化。本文的研究对象主要集中在数据加密和视觉加速两个方面。双基数系统在简化执行基本数据加密算法所需的计算方面具有很大的潜力。硬件实现的简单性直接关系到器件所需的更低的芯片面积和功率。这些都是这个市场的关键因素。这种数字系统的本质减少了晶体管的数量和它们之间的连接，从而降低了功耗和处理延迟。随着屏幕容量和数据网络速度的提高，高质量的文本生成和高分辨率的图像处理将变得越来越重要。设计用于渲染和放置文本以及解码高度压缩图像的特殊电路是未来设备的重要需求。为了让这些移动设备充分发挥其潜力，“桌面”和“移动”互联网功能之间的鸿沟需要消除。硅固有的速度和低功耗运行已经开始趋于平缓，因此我们不能仅仅依靠制造工艺来提升未来的技术。我们必须寻找通过其他方法改进共同任务处理的根本途径。

As ubiquitous mobile devices have become increasingly popular in today society and the introduction of high speed data networks (such as 4G) on the horizon and higher definition display screens, common low-level functions need to be optimized in order to maximize battery life. The object of this proposal concentrates on two major areas, data encryption and visual acceleration. The Double Base Number System has great potential in simplifying the calculations needed to perform the basic data encryption arithmetic. Simplicity in hardware implementation directly relates to lower die area and the power required for the device. These are key factors in this market. The nature of this number system reduces the number of transistors and their connections to each other, which reduces both power consumption and processing delay. High quality text generation and high-resolution image manipulation will become increasingly more important as screen capacities and data network speeds increase. Special circuits designed to render and place text as well as decode highly compressed images for multi-mega-pixel images is a significant need for future devices. The divide between "desktop" and "mobile" internet functions will need to be eliminated in order for these mobile devices to reach their full potential. The inherent speeds and low power operation of silicon have begun to flatten out, so we cannot rely on the fabrication processes alone to enhance future technology. We must look at fundamental ways to improve processing of common tasks through other methods.
