Significant advances in field-programmable gate arrays （FPGAs） have made it viable to explore innovative multiprocessor solutions on a single FPGA chip. For multiprocessors, an efficient communication network that matches the needs of the target application is always critical to the overall performance. Wormhole packet-switching network-on-chip （NoC） solutions are replacing conventional shared buses to deal with scalability and complexity challenges coming along with the increasing number of processing elements （PEs）. However, the quest for high performance networks has led to very complex and resource-expensive NoC designs, leaving little room for the real computing force, i.e., PEs. Moreover, many techniques offer very small performance gains or none at all when network traffic is light while increasing the resource usage of routers. We argue that computation is still the primary task of multiprocessors and sufficient resources should be reserved for PEs. This paper presents our novel design and implementation of a resource-efficient communication network for multiprocessors on FPGAs. We reduce not only the required number of routers for a given number of PEs by introducing a new PE-router topology, but also the resource requirement of each router. Our communication network relies on the NEWS channels to transfer packets in a pipelined fashion following the path determined by the routing network, The implementation results on various Xilinx FPGAs show good performance in the typical range of network load for multiprocessor applications.

Prostate cancer is one of the most common cancers in men. Traditional screening and diagnostic methods include digital rectal examinations （DREs）, biopsies and serum prostate-specific antigen （PSA） tests, with the latter being the more popular. PSA is a biomarker for prostate cancer; however, it is highly sensitive to external factors as well as other prostate diseases. As such, the reliability of of the serum PSA level as a sole screening and diagnostic tool for prostate cancer is controversial. Recently, it has been shown that fasting extremes can affect concentrations of serum chemistry analytes, thus raising the question of whether or not fasting has an effect on the highly sensitive PSA biomarker. Patients testing for serum PSA levels are often concomitantly submitting to other tests that require fasting, subjecting certain patients to a fasting PSA level while others not. The objective of this study was to investigate whether this discrepancy in fasting state translates into an effect on serum PSA levels. Serum PSA levels and fasting time records for 157 276 men who underwent testing at Calgary Laboratory Services （CLS; Calgary, Alberta, Canada） between 01 January 2010 and 31 March 2013 were accessed. Linear regression models of mean PSA levels and fasting times revealed a statistically important relationship at certain fasting times. Applying a dynamic mathematical model to explore the clinical effect of fasting suggests minimal impact on serum PSA result interpretation. Thus, patients can be tested for serum PSA levels regardless of their fasting state.
