FPGA Prototyping Framework on ARROW SoCKit Board with Xillybus Interface and Standard FIFO
Field Programmable Gate Array (FPGA) has been a popular candidate in hardware acceleration for offloading compute-intensive tasks from the traditional microprocessors. Due to the parallel nature, algorithm functions implemented on FPGAs can provide acceleration and are more energy efficient than …

Extensible Real-Time Sensor and Test Interface for a System-on-Chip
… Interface (SPI) and First-In/First-Out (FIFO) buses. The custom PCB includes a multiplexer circuit that allows multiple sensors to be connected to the ASIC's single SPI bus. It also includes a USB-to-FIFO interface, developed around the RP2040 microcontroller, which enables connecting a …

The psychological wellbeing of women operating mining machinery in a fly-in fly-out capacity
… work role and the impact of fly-in fly-out (FIFO) mining on their wellbeing. An Interpretative Phenomenological Approach (IPA) was used as a framework to explore the experiences of 19 female machine operators through in-depth interviewing at one mineral mine site in Queensland, Australia. IPA …

MICROARCHITECTURE OF A HIGH THROUGHPUT TEXTURE MAPPING PROCESSOR FOR INTERACTIVE 3D GRAPHICS
… instruction-data pairs from a 2-word deep input FIFO. Instructions may cause an interpolation in the S, T and Q DDAs. A single cycle decode-execute DDA controller controls all three DDA datapaths in parallel. Instructions may also initiate a computation in a dynamically configured pipeline to …

Effects of reduced IFR arrival-arrival wake vortex separation minima and improved runaway operations sequencing on flight delay
… NAS delay by 24.3% and 24.7% relative to the FIFO and Serve-the-Longest-Queue algorithms respectively.

Diastolic arrays : throughput-driven reconfigurable computing
… exclusively through First-In First-Out (FIFO) queues, and provide hardware support to guarantee bandwidth and buffer space for all data transfers. FIFO control implies that a module idles if its input FIFOs are empty, and stalls if its output FIFOs are full. The timing of data transfers …

A Priority-based Fair Queuing (PFQ) Model for Wireless Healthcare System
… used current models such as First in First Out (FIFO) and Weight Fair Queuing (WFQ). PFQ model has improved transmission of ECG sensor data by decreasing delay and jitter in emergency cases by 83.32% and 75.88% respectively in comparison to FIFO and 46.65% and 60.13% with respect to WFQ model. …

Performance evaluation of multicomputer networks for real-time computing
… desirable characteristics for real-time systems. FIFO, TDM, and token passing link access protocols and several queueing priorities are studied to measure their effect on the system’s performance. Finally, the contribution of the message parameters to the overall system delay is discussed. …

Optimal allocation of blood products
… first, thereby following first-in first-out (FIFO) policy; however, hospital blood banks would prefer that the blood center issues out the freshest units first, equivalent to a last-in first-out (LIFO) policy. This study addresses the optimal distribution policy to achieve a desired outdate, …

Parallel implementations of dynamic traffic assignment models and algorithms for dynamic shortest path problems
… list. Then we apply the framework in dynamic FIFO, strict FIFO, and static networks. Computational tests show significant speedups. We proceed to present two other shortest path algorithms: Algorithm Delta and Algorithm Hierarchy. We also provide the evaluations of the algorithms.

The effect of estimated processing times versus actual (standard) processing times on various performance measures in a pure job shop
… In addition, three priority rules, namely, FIFO, SOT and EDD, were studied to determine the best rule for controlling the shop in situations of unreliable processing times data. The percentage variation in processing times was clearly the dominant variable for most of the performance …

Impact of Queuing Schemes and VPN on the Performance of a Land Mobile Radio VoIP System
… QoS queuing schemes: first-in first-out queuing (FIFO), priority queuing (PQ), weighted fair queuing (WFQ), and class-based weighted fair queuing (CBWFQ). Quantitative results were obtained for voice application throughput, delay, jitter, and signaling overhead. Results show that, compared to a …

High Performance Applications on Reconfigurable Clusters
… Constant coefficient multipliers and a Fast FIFO implementation are also discussed in connection with the FIR filter. This filter is used in two of its structures: the direct-form and the lattice structure. The thesis describes several configurations that can be created with the different …

An experimental study of monolithic scheduler architecture in cloud computing systems
… policies in Hadoop YARN: Capacity, Fair and Fifo, over realistic workload. Based on our experiments, we observe that Fifo scheduling results in unbalanced load across cluster machines and is not suitable for enterprise clusters. We study the trade-offs exploited by Capacity and Fair …

A Safety-Performance Framework for Computational Awareness in Autonomous Robots
… us to apply the schedulers First-In-First-Out (FIFO) and Completely Fair Scheduler (CFS) of the Linux kernel on complex robotic computational tasks and compare the SP metric with baseline metrics, such as average and worst-case makespan. Extensive experimental results on NVIDIA Jetson AGX Xavier …

An application of Value Stream Mapping to reduce lead time and WIP in a make-to-order manufacturing line
… Assembly cell concept, workload balancing and FIFO lanes were proposed countermeasures or improvements to address the capacity shortfall. A decrease of 27% in manufacturing lead time was projected if these improvements were made. In addition, the capacity analysis suggests that an expansion is …

Inflation, Taxation and Corporate Investment in the U.S. During the Great Inflation
… its features – historical cost depreciation and FIFO inventory accounting – are expected to lower real after-tax corporate cash flows and, thereby, make investment less attractive when expected inflation is elevated. Using Compustat data for 1965-1980 and a difference-in-differences research …
