This paper introduces a design space explorer for coarse-grained reconfigurable KressArray architectures to enable the designer to find out the optimal KressArray architecture for a given application. This tool employs a mapper based on simulated annealing, and is highly configurable for a variety of different KressArray architectures. Using performance estimation and other statistic data, the ...

A novel parallel algorithm for matrix multiplication is presented. The hyper-systolic algorithm makes use of a one-dimensional processor abstraction. The procedure can be implemented on all types of parallel systems. It can handle matrix-vector multiplications as well as transposed matrix products.

We use the popular active appearance models (AAM) for extracting discriminative features from images of biological objects. The relevant discriminative features are combined principal component (PCA) vectors from the AAM and texture features from cooccurrence matrices. Texture features are extracted by extending the AAM’s with a textural warp guided by the AAM shape. Based on this, texture cooc...

Welcome to ASAP 2006: the 17 IEEE International Conference on Application-specific Systems, Architectures and Processors, held in picturesque Steamboat Springs nestled in the Colorado Rockies. This year is the twentieth anniversary of the ASAP conference series that started in 1986 in Oxford, UK as the “International Workshop on Systolic Arrays.” Over the years we kept the ASAP acronym, while i...

The effects of physiological arousal on persuasion are investigated. An exercise task was used to manipulate physiological arousal, and systolic biood pressure readings were taken to assess the effectiveness of this manipulation. The resuits indicate that endorser status (celebrity or noncelebrity) has a stronger influence on brand attitudes under high than under moderate levels of physiologica...

Kestrel is a programmable linear systolic array processor designed for sequence analysis. Among other features, Kestrel includes an 8-bit word, a single-cycle add-and-minimize instruction, and e cient communication using Systolic Shared Registers. This paper describes Kestrel's functional units in detail, and examines each of their e ects on system performance. With prototypes currently in the ...

We present an all-optical ring network architecture with logarithmic shortcuts and a systolic routing protocol for it. An r-dimensional optical ring network with logarithmic shortcuts (ORLS) consists of n = 2 nodes and r2 optical links. We study a systolic routing protocol that is based on cyclic changes of the states of routers and scheduled sendings of packets. The protocol ensures that no el...

This chapter compares Peter Montgomery's modular multiplication method with traditional techniques for suitability on hardware platforms. It also covers systolic array implementations and side channel leakage. 3.

Dynamic cardiomyoplasty is a recently developed operation for the treatment of end-stage heart failure. Recent studies have focused on the potential mechanism by which it may work. We have shown in a canine model of heart failure, using transformed muscle, that CMP has at least two mechanisms. First, it stabilizes ventricular function and volumes chronically by a girdling mechanism. Secondly, d...

Results. Twenty women required a second bolus of oxytocin 5 u. Both the first and the second doses produced clinically and statistically significant haemodynamic changes, but the haemodynamic changes induced by the second dose were smaller than after the first dose. The mean maximal change in CO after the first and second doses were 94% (CI 70–117) and 42% (CI 33–52), respectively (P,0.0001), a...
