The main goal of this diploma work is the implementation of Matsui's linear cryptanalysis of DES and a statistical and theoretical analysis of its complexity and success probability. In order to achieve this goal, we implement first a very fast DES routine ...
Continuous transistor scaling due to improvements in CMOS devices and manufacturing technologies is increasing processor power densities and temperatures; thus, creating challenges to maintain manufacturing yield rates and reliable devices in their expecte ...
Autofluorescence bronchoscopy (AFB) has been shown to be a highly sensitive tool for the detection of early endobronchial cancers. When excited with blue-violet light, early neoplasia in the bronchi tend to show a decrease of autofluorescence in the green ...
Recent research advocates address-correlating predictors to identify cache block addresses for prefetch. Unfortunately, address-correlating predictors require correlation data storage proportional in size to a program's active memory footprint. As a result ...
Wireless Sensor Network (WSN) nodes require components with ultra-low power consumption, as they must operate without an external power supply. One technique for reducing consumption of a system is to scale it to a smaller technology; however, in recent te ...
Current simulation-sampling techniques construct accurate model state for each measurement by continuously warming large microarchitectural structures (e.g., caches and the branch predictor) while functionally simulating the billions of instructions betwee ...
Superscalar out-of-order microarchitectures can be modified to support redundant execution of a program as two concurrent threads for soft-error detection. However, the extra workload from redundant execution incurs a performance penalty due to increased c ...
We revisit the idea of using small line buffers in-front of caches. We propose ReCast, a tiny tag set cache that filters a significant number of tag probes to the L2 tag array thus reducing power. The key contribution in ReCast is S-Shift, a simple indexin ...
A statistical approach for the area efficient implementation of fast wide operand adders using early termination detection is described and analyzed. It is shown that high throughput can be achieved based on area- and routing-efficient ripple-carry adders ...

Previous proposals for soft-error tolerance have called for redundantly executing a program as two concurrent threads on a superscalar microarchitecture. In a balanced superscalar design, the extra workload from redundant execution induces a severe perform ...
