In this paper, we present the MorphoSys reconfigurable architecture, which combines a configurable array of processing elements with a RISC processor core. We provide a system-level model, describing the array architecture and the inter-connection network. We give several examples of applications that can be mapped to the MorphoSys architecture. We also show that MorphoSys achieves performance ...

A multi-core cluster is a cluster composed of numbers of nodes where each node has a number of processors, each with more than one core within each single chip. Cluster nodes are connected via an interconnection network. Multi-cored processors are able to achieve higher performance without driving up power consumption and heat, which is the main concern in a single-core processor. A general pro...

This final technical report was prepared for the Air Force Research Laboratory, under award #FA8750-08-1-0024, titled “MultiCore Hardware Experiments in Software Producibility,” responsible program officer, Steven Drager. This report details our findings when taking heterogenous systems software, designed for a distributed environment, and running it on a single-core, and later multi-core, comp...

An MPEG-2 audio decoding processor core is described with a focus on inverse quantization (IQ) and multichannel processing (MC) of Layer I and II decoding. A novel architecture that we propose can perform IQ at a high throughput. In addition, different types of dematrixing modes for MC process in the MPEG-2 standard can also be performed. The processor core is implemented and controlled with a ...

We have benchmarked dual-processor quad-core AMD Opteron 2350 and 2356, dual-processor quad-core Intel Xeon E5345, single processor quad-core Intel Xeon X5472, dual-processor dual-core AMD Opteron 2214, dual-processor single-core Intel Xeon EM64T and single-processor single-core Intel Xeon EM64T systems using a CMSSW event simulation and reconstruction application. The results are presented in ...

Multi-core clusters have emerged as an important contribution in computing technology for provisioning additional processing power in high performance computing and communications. Multi-core architectures are proposed for their capability to provide higher performance without increasing heat and power usage, which is the main concern in a single-core processor. This paper introduces analytical...

The past two decades have witnessed tremendous progress in seismological, geodynamical, geomagnetic, and mineral physics efforts to quantify deep Earth processes. Our understanding of structures and processes in the lowermost mantle has advanced accordingly, and there is now widespread agreement that some form of major thermo-chemical boundary layer (TCBL) exists on the mantle side of the core-...

We present an overview of the Synchroscalar single-chip, multi-core processor. Through the design of Synchroscalar, we find that high energy efficiency and low complexity can be attained through parallelization. The importance of adequate inter-core interconnect is also demonstrated. We discuss the impact of having multiple frequency and voltage domains on chip to reduce the power consumption w...

Techniques for library-centric application design have already proven to be very useful in the past. The current gain in computer performance is shifted towards the utilisation of multi-core processors which extends the importance of this type of application design in the field of scientific computing, which also poses new difficulties. A parallel generic scientific simulation environment has b...
