Significant advances have been made in compilation technology for capitalizing on instruction-level parallelism (ILP). The vast majority of ILP compilation research has been conducted in the context of general-purpose computing, and more specifically the SPEC benchmark suite. At the same time, a number of microprocessor architectures have emerged which have… (More)
Most modern microprocessors employ one or two levels of on-chip caches in order to improve performance. These caches are typically implemented with static RAM cells and often occupy a large portion of the chip area. Not surprisingly, these caches often consume a significant amount of power. In many applications, such as portable devices, low power is more… (More)
In this study we introduce NetBench, a benchmarking suite for network processors. NetBench contains a total of 9 applications that are representative of commercial applications for network processors. These applications are from all levels of packet processing; Small, low-level code fragments as well as large application level programs are included in the… (More)
Digital system designs are the product of valuable effort and know-how. Their embodiments, from software and HDL program down to device-level netlist and mask data, represent carefully guarded intellectual property (IP). Hence, design methodologies based on IP reuse require new mechanisms to protect the rights of IP producers and owners. This paper… (More)
– This work presents the first known attempt to leverage the unique characteristics of FPGAs to protect commercial investments in intellectual property. A watermark is applied to the physical layout of a digital circuit when it is mapped into an FPGA. This watermark uniquely identifies the circuit origin and yet is difficult to detect. While this approach… (More)
It has been estimated that computer network worms and virus caused the loss of over $55B in 2003. Network security system use techniques such as deep packet inspection to detect the harmful packets. While software intrusion detection system running on general purpose processors can be updated in response to new attacks. They lack the processing power to… (More)

Searching for multiple string patterns in a stream of data is a computationally expensive task. The speed of the search pattern module determines the overall performance of deep packet inspection firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS). For example , one open source IDS configured for 845 patterns, can sustain a… (More)
