These simulations often require one or more Gaussian distributed pseudorandom number sources. Although uniformly distributed pseudorandom number sources can be readily implemented, Gaussian sources are not as easily configured. A typical method is to build a uniform source and transform the distribution to Gaussian. The inversion method accomplishes the transformation by the application of the inverse Gaussian cumulative distribution function (IGCDF). The IGCDF is easily obtained by the use of a look-up table (LUT). However, the memory required for the LUT can become large if it is to accurately represent the IGCDF. In this paper we demonstrate a method that can reduce the size of this LUT while allowing for control of the accuracy.","PeriodicalId":325631,"journal":{"name":"2009 International Conference on Reconfigurable Computing and FPGAs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114662628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, it is a good candidate for acceleration with FPGAs. The aim of this paper is two-fold. First, building upon our prior BLAST work we describe a design composed of multiple cores that can be scaled in two dimensions. The ungapped extension and a second dimension are new in this work. Second, we use this non-trivial example to explore spatially scalable designs. To provide the ability to move the design to a future generation chip, a mathematical model of performance that incorporates all of the system design parameters and the user’s preference (high throughput vs low latency) is developed. We demonstrate here that the model correctly predicts the optimal ratio between the two dimensions on a Xilinx Virtex-4 and measures four to five times faster performance figures as compared to a state of the art general purpose processor.","PeriodicalId":325631,"journal":{"name":"2009 International Conference on Reconfigurable Computing and FPGAs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123468102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since reconfigurable computers provide limited possibilities for customizing the organization of external memory, a specific challenge is to make use of the existing memory layout in a flexible, yet efficient way. In this paper we build on IMORC, our architectural template and on-chip network for creating reconfigurable accelerators, and discuss its infrastructure for accessing memory. We characterize the IMORC communication bandwidth on the XtremeData XD1000 reconfigurable computer. Based on this characterization, we present a z-buffer compositing accelerator which is able to double the frame-rate of a parallel renderer.","PeriodicalId":325631,"journal":{"name":"2009 International Conference on Reconfigurable Computing and FPGAs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129237865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to long memory and stochastic non-idealities in the pyrosequencing process, exact inference on the proposed dynamic Bayesian learning network is computationally prohibitive in both run-time and memory usage for reasonable problem sizes. To circumvent these issues, we design a reconfigurable Bayesian learning network, whereby processing nodes evaluate posterior probabilities of all states in parallel and crossbar switch realizes network topology that interconnects all processing nodes. The success of the proposed method is demonstrated by a prototype system implemented with Berkeley Emulation Engine 3 (BEE3) board, which achieves close to 2 times increase in read length and about 3 orders of reduction in run-time than previously reported for both experimental and simulated pyrosequencing data.","PeriodicalId":325631,"journal":{"name":"2009 International Conference on Reconfigurable Computing and FPGAs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124978693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fact, with specific development tools, platforms such as Xilinx Virtex-5 or Virtex-6 FPGA can implement multiprocessor systems (with soft-core and hard-core processors) {with just a few mouse clicks} and offer the possibility of partial and dynamic reconfiguration. Software tasks are scheduled on these platforms by embedded and distributed Real Time Operating System (RTOS). To provide high performance (execution time, power consumption...) to these Multiprocessor Soc (MPSoC) platforms, the RTOS can enable the migration of software tasks between processors. Our work deals with the study and the development of a software layer (an application programming interface) which allows task migration between soft-core processors. The soft-core can be dynamically loaded on FPGA on demand. In this paper, we present a platform that merges these two aspects, partial reconfiguration and software task migration in the context of MPSoCs. We notably investigate the incurred time and overhead for task migration and partial reconfiguration.","PeriodicalId":325631,"journal":{"name":"2009 International Conference on Reconfigurable Computing and FPGAs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122330996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the advantages of FPGAs implementations is the parallel process capability, allowing acceleration of complex algorithms. Nowadays it is common to find FPGA implementations in applications requiring high speed processing. In this paper a hardware architecture for computing direct kinematics of robot manipulators using floating-point arithmetic is presented for 32, 43 and 64 bit-width representations. Otherwise, the processing time of the hardware architecture is compared with the same formulation implemented in software, using the PowerPC (FPGA embedded processor).

A case study is discussed to demonstrate an example of swapping a Flash memory controller and an SRAM controller in response to diverse memory access needs. Result analysis reveals a more efficient resource utilization of 52.1% I/O pads, 86.5% LUTs and 81.3% Flip-Flops, when compared to the static design with same functionalities. A small reconfiguration overhead of context switching is measured within the range from hundreds of microseconds to milliseconds.

Nonuniform heating of chips due to hotspots is also an area of concern and much research. In this paper, we propose an adaptive method which takes advantage of the self-reconfiguration capability of modern FPGAs to mitigate hotspots. We adapt the floor plan of the IC in response to the current use and ambient conditions on the fly. It is most applicable to paradigms such as Network on Chip (NoC) that allow separation of communication and computation and allow communication between modules to be abstracted away. We achieve a reduction of up to 8 ¿C in the maximum temperature of a hotspot using typical power numbers. Alternatively, by increasing the frequency, we achieve a 2-3 times increase in throughput while maintaining the same maximum temperature.","PeriodicalId":325631,"journal":{"name":"2009 International Conference on Reconfigurable Computing and FPGAs","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133863763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
