We show that an efficient hardware-software partitioning algorithm is required when targeting low-power. However, if the application objective is performance, then we propose the use of dynamically reconfigurable architectures. This work presents a configuration-aware data size partitioning approach. We propose a design methodology that adapts the architecture and used algorithms to the application requirements. The methodology has been proven to work on a real research platform based on Xilinx devices. Finally, we have applied our methodology and algorithms to the case study of image sharpening, which is required nowadays in digital cameras and mobile phones.","PeriodicalId":127038,"journal":{"name":"International Conference on Hardware/Software Codesign and System Synthesis, 2004.

Low energy security optimization in embedded cryptographic systems 嵌入式密码系统的低能耗安全优化

{"title":"Low energy security optimization in embedded cryptographic systems","authors":"C. Gebotys","doi":"10.1109/CODES+ISSS.2004.38","DOIUrl":"https://doi.org/10.1109/CODES+ISSS.2004.38","url":null,"abstract":"Future embedded and wireless devices are increasingly powerful supporting many applications including one of the most crucial; security. Although many wireless and embedded devices offer more resistance to bus probing attacks due to their compact size, susceptibility to power/electromagnetic attacks must be analyzed. This work presents optimized synthesis of new low energy masking countermeasures into cryptographic software. In particular a model for key masking with the objective of minimizing energy overhead is presented. Experimental results using real power measurements are shown to support up to 2.5 energy overhead savings and improved security compared to previous research. With the emergence of security applications in PDAs, cell phones, line card accelerators, etc, optimizing low energy countermeasures for resistance to power/ electromagnetic attacks is crucial for supporting future secure embedded devices.","PeriodicalId":127038,"journal":{"name":"International Conference on Hardware/Software Codesign and System Synthesis, 2004.

Our approach is targeted towards design space exploration (DSE) and thus the speed of synthesis is of critical interest. The focus here is on the problem of resource allocation and binding with a view to optimize cost under performance constraints. Our approach exploits adjacency relation of processes and uses a dynamic programming based algorithm to synthesize the architecture including interconnection network. We have done a number of experiments on real as well as randomly generated process networks. The results have been compared with an optimal MILP formulation. They conclusively show that this approach is fast as well as effective and can be employed for DSE.","PeriodicalId":127038,"journal":{"name":"International Conference on Hardware/Software Codesign and System Synthesis, 2004.

A loop accelerator for low power embedded VLIW processors 用于低功耗嵌入式VLIW处理器的环路加速器
B. Mathew, A. Davis
{"title":"A loop accelerator for low power embedded VLIW processors","authors":"B. Mathew, A. Davis","doi":"10.1109/CODES+ISSS.2004.1","DOIUrl":"https://doi.org/10.1109/CODES+ISSS.2004.1","url":null,"abstract":"The high transistor density afforded by modern VLSI processes has enabled the design of embedded processors that use clustered execution units to deliver high levels of performance. However, delivering data to the execution resources in a timely manner remains a major problem that limits ILP. It is particularly significant for embedded systems where memory and power budgets are limited. A distributed address generation and loop acceleration architecture for VLIW processors is presented. This decentralized on-chip memory architecture uses multiple SRAMs to provide high intra-processor bandwidth. Each SRAM has an associated stream address generator capable of implementing a variety of addressing modes in conjunction with a shared loop accelerator. The architecture is extremely useful for generating application specific embedded processors, particularly for processing input data which is organized as a stream. The idea is evaluated in the context of a fine grain VLIW architecture executing complex perception algorithms such as speech and visual feature recognition. Transistor level Spice simulations are used to demonstrate a 159x improvement in the energy delay product when compared to conventional architectures executing the same applications.","PeriodicalId":127038,"journal":{"name":"International Conference on Hardware/Software Codesign and System Synthesis, 2004.

In this context, the goal of This work is to highlight advantages and drawbacks derived from the exploitation of polymorphism in the design of an ATM component: the UTOPIA cells handler.","PeriodicalId":127038,"journal":{"name":"International Conference on Hardware/Software Codesign and System Synthesis, 2004.
