Wafer Scale Integration of Parallel Processors

Single-Scale Retinex Using Digital Signal Processors

The Retinex is an image enhancement algorithm that improves the brightness, contrast and sharpness of an image. It performs a non-linear spatial/spectral transform that provides simultaneous dynamic range compression and color constancy. It has been used for a wide variety of applications ranging from aviation safety to general purpose photography. Many potential applications require the use of...

Growing large-scale cellular arrays of processors

Molecular-scale integrated circuits will provide hardware designers with astounding computational resources. However, current design methodologies—which already struggle to exploit the resources available today—are ill-suited to the complexity and high fault rates of these novel technologies. Nature, on the other hand, has evolved ways of coping with these issues. A human being consists of appr...

Evaluating Register Assignment Strategies on Out - of - order IssueSuperscalar Processors

Register allocation impacts the performance of programs on ne-grain parallel architectures. The al-locator can introduce dependences that did not exist among the original code sequence, preventing instructions from being executed in parallel. What is not well-understood is the impact of the allocation on code targeted for an out-of-order issue, super-scalar architecture. The dynamic scheduling ...

Confidence Based Out-of-Order Renaming for Speculatively Multithreaded Processors

Speculatively multithreaded processors find parallelism by speculatively fetching and renaming dynamic flows of instructions from (perhaps) widely seperated parts of the program flow graph. These processors must handle inter-thread register dependences. The approach followed in this paper is to dynamically identify the consumers of interflow register mappings that will be (but have not yet been...
